Zika infections in Puerto Rico


According to National Public Radio (NPR), health researchers have reported that the number of new cases of Zika infections in Puerto Rico has risen to over 34,000 since 2015. The Center for Disease Control (CDC) states that the virus peaked during the summer months of 2016, with more than 2,000 new cases being reported per week.

Because Zika is a relatively new epidemic, individuals living in Puerto Rico have not yet developed any immunity to the virus. Therefore, the transmission of the disease has been rampant.

In more recent months, the number of Zika infections in Puerto Rico has decreased to around 200 new cases per week. However, it continues to remain a serious problem within the region. Researchers from the CDC have confirmed that the number of Zika infections in Puerto Rico has far surpassed that of dengue virus infections. Dengue is another disease most commonly spread by mosquitoes.

The Zika virus is transmitted via the bite of an infected Aedes species mosquito. Pregnant women who become infected are especially at risk of the disease.  Those infected are likely to pass on the infection to the fetus during pregnancy, which can lead to serious birth defects. Additionally, sexual relations and blood transfusions can spread the virus. Common symptoms of Zika virus include fever, rash, headaches, muscle pain and red eyes.

As of 2017, over 1,000 confirmed cases of reported Zika infections in Puerto Rico were among pregnant women. Doctors at the High-Risk Clinic at the University of Puerto Rico have treated some of these infected women. They witnessed at least 14 cases of babies born with severe brain damage.

Notwithstanding, some babies may not begin to show signs of defects or abnormalities until several years after birth. This calls for babies to be closely monitored by health professionals for up to four or five years after birth.

The CDC has listed different recommendations for preventing contraction of the disease. These recommendations are especially important because of the lack of a vaccine for the disease. Some of their recommendations include wearing long-sleeved shirts and long pants when mosquitoes are around, ridding homes of any standing water and using insect repellents registered by the Environmental Protection Agency. They especially advise against pregnant women traveling into Puerto Rico or any other areas where the virus is present.

Top Three Deadliest Diseases in Botswana


Located in Southern Africa, Botswana is one of Africa’s most stable countries, with a solid economy built on diamonds and Safari-based tourism. However, the country continues to struggle with high rates of HIV/AIDS, as well as other preventable diseases. Here are the top three deadliest diseases in Botswana:

1. HIV

HIV is not only one of the deadliest diseases in Botswana, but it is also the number one cause of death, accounting for 32 percent of all deaths in the country. Despite the disease’s prevalence, the Ministry of Health’s national HIV program has helped efforts progress. Approximately 96 percent of people in need of HIV treatment in Botswana have received it. Increased prevention of mother-to-child transmission has reduced the transmission rate to less than four percent.

2. Malaria

While seven percent of deaths each year are due to malaria, Botswana has significantly reduced the disease’s burden. Government interventions, such as establishing rapid response teams and adequate healthcare facilities, has helped reduce incidences from 0.99 to 0.01 percent between 2000 and 2012. Botswana’s progress has not gone unnoticed. In 2016, the country received the African Leaders Malaria Alliance (ALMA) Award for its progress in reducing malaria.

3. Tuberculosis (TB)

Tuberculosis is very common in Botswana, causing six percent of deaths each year. Part of what makes TB so dangerous is that it is a common opportunistic infection in people with HIV. In Botswana, 75 percent of patients with TB are HIV-positive. TB rates began rising in Botswana with the increase in HIV/AIDS in the 1990s, with rates from 200 cases per 100,000 people in 1990 to 620 per 100,000 in 2002. With the help of international partners, the government has launched numerous programs aimed at increasing testing, prevention and awareness of the link between HIV and TB.

Despite its steady economy and stable government, Botswana continues to suffer from high rates of preventable diseases. That said, the government has made significant progress in reducing this prevalence of these diseases and continues to dedicate important time and resources to prevention.

Top Diseases in Dominica

Diseases in Dominica
Dominica is an eastern Caribbean nation with clusters of coastal communities and a sparsely populated volcanic interior. The top diseases in Dominica are chronic non-communicable diseases (CNCDs), responsible for 52 percent of deaths. According to a survey taken in Dominica, from 2005 to 2009, the main causes of death were strokes, diabetes, and heart diseases. The survey also shows the number of deaths on the island due to CNCDs:

  • Strokes, coronary ischemia, heart disease and hypertension: 333 deaths
  • Diabetes mellitus: 228 deaths
  • Ischemic heart disease: 206 deaths
  • Malignant neoplasm of prostate: 176 deaths
  • Hypertensive diseases: 165 deaths
  • Acute respiratory infection: 137 deaths
  • Other forms of heart disease: 120 deaths
  • Chronic lower respiratory diseases: 96 deaths
  • Heart failure: 84 deaths
  • Malignant neoplasm of digestive organs and peritoneum: 66 deaths

According to Pan American Health Organization director Carissa Etienne, Dominican health statistics are concerning. “For every three persons, one has high blood pressure. For every five persons in Dominica, one has diabetes. For every four persons in Dominica, one has high cholesterol. For every two people in Dominica, one is overweight or obese,” Etienne said.

Most diseases in Dominica are caused by preventable risk factors including tobacco use, unhealthy diet, physical inactivity and the harmful use of alcohol. These can be prevented with a change in lifestyle.

According to healthdata.org, in 2015, the highest cause of death in Dominica was from cardiovascular complications, at 55.8 percent. Chronic kidney disease resulted in the most combined death and disability, affecting more than 30 percent of people that year. The second-highest contributor was cerebrovascular disease, with more than 20 percent of people becoming disabled.

Furthermore, diabetes is becoming a prevalent disease in Dominica. From 2005 to 2015, diabetes affected 19.9 percent of the population. According to the International Diabetes Federation, in 2015, there were 6,000 cases of diabetes. Pan American Health Organization representative for Barbados Godfrey Xuereb said the prevalence of diabetes in Dominica had risen from about five percent in 1980 to almost 15 percent in 2014.

The number of CNCDs is very high. However, Dominica has been holding conferences to address the situation. Doctors have brought this problem to light, and have been working on ways to help people stay aware of their health and to take care of themselves.

Severe Diseases in Nauru


Among the various diseases in Nauru, the most serious and commonly transmitted in the country are dengue fever and typhoid fever.

Dengue Fever: Cause and Symptoms

According to WebMD, dengue fever is a disease that is transmitted through the bite of an infected Aedes mosquito. Unlike many other diseases in Nauru, dengue fever cannot be transmitted via person-to-person contact. Symptoms common to the disease include high fever, vomiting, fatigue, skin rash, nosebleeds, and bruising. If left untreated, it is potentially life-threatening.

Recently, dengue fever has been a rising epidemic in Nauru. Medical researchers have confirmed at least 70 cases of dengue fever within the country. While there has been a rapid increase in infections, Nauru is currently working with a limited amount of treatment supplies.

Nauruan government officials have met with officials from the World Health Organization (WHO), the Australian government, and hospital staff members of International Health and Medical Services, in order to develop an effective solution to the epidemic. However, due to limited medical resources, some infected patients have been evacuated to Australia for proper treatment.

Typhoid: Causes and Symptoms

Another common disease, typically transmitted through contaminated food and water in Nauru, is typhoid. Common symptoms of typhoid include high fever, headaches, stomach pains, loss of appetite, internal bleeding and in extreme cases, death.

The risk of infection is especially high in Nauru and the surrounding regions, so the Center for Disease Control (CDC) highly recommends that potential travelers get vaccinated before traveling into the country.

Travelers who reside with friends or relatives, visit small cities and eat “risky” foods face the highest risk of becoming infected with typhoid disease. The CDC recommends that travelers into the country be especially cautious of the kinds of food and drink that they consume, such as tap or well water, salads, unwashed raw fruit and food from street vendors.

One of the best ways to avoid contracting typhoid, as well as other diseases in Nauru, is to keep hands washed and well-sanitized. It is also best to avoid all physical contact with individuals who are infected with the disease.

Threatening Diseases in Croatia


With an evolving population of 4.3 million people, Croatia is known for its rich historical culture, beautiful landscapes and pleasant climate. As a result, Croatia has become a booming tourist destination. Although widely known for its attractions, many transmittable diseases in Croatia threaten the health of its population and the country’s tourism industry.

Here are just a few of the threatening diseases in Croatia:

Typhoid Fever

Typhoid fever is a systemic infection, usually contracted through contaminated food or water. The symptoms include prolonged fever, nausea, headache, loss of appetite and constipation or diarrhea. It thrives in areas with poor sanitation and lack of clean drinking water. According to a study published in 2014, approximately 21 million cases and 222,000 typhoid-related deaths occur annually worldwide, demonstrating the real threat that this communicable infection poses.

Currently, there are two typhoid vaccines that are recommended for use, including an injectable polysaccharide vaccine (Vi-PS vaccine) for persons of age two years and above. The other vaccine is a live attenuated oral Ty21a vaccine for those over five years of age.

Malaria

Malaria is a life-threatening disease caused by parasites that are transmitted through mosquito bites. The symptoms include fever, headache, chills and vomiting, which usually appear within 7 days or more (usually 10-15 days). If not treated quickly, this can progress to severe illness, often leading to death.

Malaria is preventable and curable, easing the burden in many countries around the world. Currently, there are no licensed vaccines against malaria or any other human parasite. However, with insecticide-treated mosquito nets and antimalarial drugs, malaria can be prevented.

Hepatitis B

As a viral infection that attacks the liver, hepatitis B is a virus that is transmitted through contact with blood or other bodily fluids of an infected person. Every year, more than 686 million people die due to the complications of hepatitis B, including cirrhosis and liver cancer.

A vaccine against hepatitis B is available in preventing the infection and the development of chronic disease and liver cancer complications. However, the treatment does not cure all cases of hepatitis B. By only suppressing the replication of the virus, lifelong treatments are necessary in order to fight against the complications of the virus.

Although the diseases in Croatia are constantly threatening the health of the country’s population and its tourism industry, many are continuing to develop innovative methods to help bring vaccinations and preventable solutions to Croatia, potentially saving millions of lives.

Striving to End World Hunger: 20 Key Facts

world hunger facts
While progress has been made in the effort to end world hunger, one in nine people around the world still go to bed hungry. Here are 20 world hunger facts:

Top World Hunger Facts

  1. Roughly 795 million people, or one in nine, of the 7.3 billion people in the world are suffering from chronic undernourishment.
  2. Of the 795 million suffering from hunger, 780 million live in developing countries. That is 12.9 percent of developing countries’ population.
  3. World hunger is dropping. The number of undernourished people in developing countries was reduced by 42 percent between 1990 and 2014.
  4. Hunger is most prevalent in Asia and sub-Saharan Africa. Two out of three of the world’s undernourished people live in Asia. In addition, one in four people in sub-Saharan Africa is undernourished.
  5. There are two types of malnutrition. The first is protein-energy malnutrition, which is a lack of calories and protein. The second is micronutrient deficiency, which is a shortage of vitamins and minerals. While both are important, protein-energy malnutrition is the focus of world hunger discussions.
  6. Every year, hunger kills more people than AIDS, malaria and tuberculosis combined.
  7. Sixty percent of the world’s hungry people are women.
  8. Hunger affects women’s pregnancies. Each year, around 17 million children are born undernourished because their mother was undernourished while pregnant.
  9. Every 10 seconds a child dies due to a hunger-related disease.
  10. World hunger is caused by inequality and poverty, not a shortage of food. The world already produces enough food to feed roughly 10 billion people.
  11. Food waste contributes to global hunger. One-third of the food produced each year is wasted, which costs the global economy close to $750 billion annually.
  12. In developing countries, approximately 896 million people live on $1.90 a day or less.
  13. Food aid, not including emergency relief, is often more damaging in the end. This is because free or subsidized food shipped from the U.S. and Europe and sold below market prices hurt local farmers who cannot compete.
  14. Approximately 66 million primary school-age children in the developing world attend classes hungry. This has a negative impact on their futures, as hungry children spend fewer years in school and cannot concentrate.
  15. The U.N.’s World Food Programme works to end world hunger by providing free meals and snacks in schools around the world. In 2015, the program provided 17.4 million children with meals or snacks. This not only helps to feed children around the world but is also an incentive for parents to send them to school.
  16. People involved in agriculture are especially susceptible to hunger. Fifty percent of hungry people in the world are farming families.
  17. Gender equality is a vital part of efforts to end world hunger. Around half of the world’s farmers are women, but they do not have access to the same tools, such as training and land rights, as men. If men and women had the same resources, female farmers could increase their productivity to help reduce world hunger for approximately 1.5 million people.
  18. One possibility for reducing world hunger is sustainable agriculture, which aims to preserve the Earth’s natural resources, through things like crop waste recycling and more precise fertilizer use.
  19. Microfinance also has the potential to end world hunger. These programs help to reduce poverty and improve gender equality through providing poor people, particularly women, with credit to develop small businesses.
  20. The U.N. estimated that it would take roughly $30 billion a year to end world hunger.

Undernourishment remains a pressing issue in both developing and developed countries; however, new research and technology reveal promising solutions to help end world hunger.

Severe Diseases in Benin

Diseases in Benin
Benin is a relatively stable democratic West African nation that lies between Togo and Nigeria. There are a number of diseases in Benin putting the health of its residents at serious risk. Malaria and meningococcal meningitis are among the top diseases in Benin. Both are potentially life-threatening for individuals who become infected.

The Fight Against Malaria

Malaria is a severe and life-threatening blood disease transmitted through the bite of the Anopheles mosquito. According to the Centers for Disease Control and Prevention (CDC), malaria is considered to be one of the high-risk diseases in Benin, affecting all areas of the country. As a result, it recommends that all potential travelers into the country get vaccinated prior to entering.

There are different mechanisms in place aimed at fighting against diseases in Benin. In 2005, the President’s Malaria Initiative (PMI) was created to help reduce the spread of malaria in particular. Researchers working in conjunction with PMI have found that malaria is currently the leading cause of health problems in Benin, and that it “accounts for 40 percent of outpatient consultations and 25 percent of all hospital admissions.” Consequently, families are forced to spend large amounts of money paying for treatments.

In response to this issue, PMI has been making progress in helping residents of Benin fight against malaria by providing residents with valuable resources such as trained healthcare workers, insecticide treatments, house-sprays and Rapid Diagnostic Tests. As of 2016, PMI has raised $155.2 million toward the effort.

The Fight Against Meningococcal Meningitis

In addition to malaria, meningococcal meningitis is another of the high-risk bacterial diseases in Benin. It is also common in other parts of sub-Saharan Africa.

Meningococcal meningitis causes inflammation of the brain and spinal cord. It is typically transferred via person-to-person contact. Some common symptoms associated with the disease are vomiting, headaches, neck stiffness and fever.

Furthermore, it has also been classified as one of the high-risk diseases in Benin, particularly during December through June. The CDC has recommended that persons traveling to the country during these months get vaccinated to help protect themselves from contracting the virus.

In response to this epidemic, the World Health Organization (WHO) has developed a strategy to help reduce the spread of meningococcal meningitis in Benin and surrounding countries. The WHO strategy consists of vaccinating everyone under 29 in the African meningitis belt with the MenA conjugate vaccine, and using “prompt and appropriate case management with reactive mass vaccination of populations not already protected through vaccination.”

The Importance of Diet for the Top Diseases In Japan


The World Health Organization (WHO) Centre for Health Development, also known as WHO Kobe Centre (WKC), invited Japan-based research institutes to submit proposals designed to strengthen universal health coverage for aging populations and address the top diseases in Japan.

The proposals are expected to address one or a combination of issues, including the integration of community-based care systems, technological innovations, the need for human resources, and prevention of Non-Communicable Diseases (NCDs). NCDs are long-term diseases that are not caused by infectious agents and progress slowly, such as cancer and cardiovascular diseases.

Japan’s Top Non-Communicable Diseases

In 2015, the population of Japan reached 128.3 million and the nation had a death rate of 1,100 for every 100,000 people. According to the Institute for Health Metrics and Evaluation (IHEM), from 2005 to 2015, the top diseases in Japan were cerebrovascular disease, Ischemic heart disease, and Alzheimer’s disease.

Cerebrovascular disease is a generic term for a variety of health conditions, all of which directly limit or cease blood flow to the brain. From 2005 to 2015, fatal cases increased by 15.4 percent in Japan. Atherosclerosis is the most common form of cerebrovascular disease, developing from high cholesterol levels and inflammation in the carotid arteries. Cholesterol collects along the artery walls, forming a barrier of plaque and restricting blood flow. Risk factors include smoking, obesity, diabetes, and hypertension.

Ischemic heart disease is caused by the reduction of blood supply to the heart. Between 2005 and 2015, deaths caused by Ischemic heart disease increased by 24.4 percent. Plaque accumulates inside the coronary arteries, slowly decreasing blood flow. Blood flow restriction and plaque ruptures often lead to a heart attack. Risk factors for ischemic heart disease include smoking, high blood pressure, high cholesterol, diabetes and obesity.

Alzheimer’s disease is irreversible and progresses through the brain slowly, eventually destroying the ability to complete the simplest tasks. From 2005 to 2015, Alzheimer’s had the largest increase in fatal cases at 56.2 percent. The cause of this diseases is not fully understood, however, there are common factors. Alzheimer’s disease typically affects elderly men and women, people with the ApoE-e4 gene, and in some cases, individuals with vascular conditions such as stroke, high blood pressure, and heart disease.

How Diet Affects These Diseases

Cardiovascular and chronic respiratory diseases are the top NDCs caused by dietary risks. A diet rich in antioxidants and grains is necessary to prevent these and other health-related diseases. Traditionally, Japanese food is relatively low in fat, but high in sodium. High levels of sodium directly affect the cardiovascular system, potentially leading to stroke, heart disease, and heart failure. The nutritional value of a Japanese diet — primarily based on wheat, rice, fish, and soy — lacks vital nutrients found in nuts and whole grains.

High blood pressure contributes to many of the top diseases in Japan. Exercising daily and eating a healthy diet are vital to reducing high blood pressure. A variety of multigrain and whole-grain products, such as oats and bran, can help lower blood pressure. A diet plan known as Dietary Approaches to Stop Hypertension (DASH), is based on the National Institute of Health (NIH) research to lower blood pressure without the use of medication. The DASH diet primarily focuses on eliminating sodium and dairy and increasing consumption of vegetables, fruits, nuts, beans, seeds, and whole grains.

Advanced health and social services for aging populations are critical components to sustaining universal health coverage. The Japan Times reports that elderly people aged 65 or older make up 26.7 percent of the total population. This percentage is predicted to rise, altering the demographic structure of Japan and the need for medical care. The WKC’s primary objective is to create, “more sustainable and inclusive policies and programs for aging populations”, which is vital to achieving a complete understanding and potential cure for the top diseases in Japan.

6 Facts About Treating Diabetes in Africa


Diabetes is a serious chronic disease that occurs due to the body’s inability to produce insulin, which regulates sugar levels in the body (Type 1), or when the body cannot effectively use the insulin it produces (Type 2). A recent report by the World Health Organization (WHO) found that the global prevalence of diabetes has nearly doubled since 1980, rising from 4.7 percent to 8.5 percent. This trend is particularly troubling, as diabetes prevalence has risen faster in low and middle-income countries. In many of these countries, diabetes is an added burden to states already struggling to deal with weak economies, weak health systems and significant infectious disease burdens. This is especially true for African countries. Here are six facts about diabetes in Africa:

  1. The prevalence of diabetes in African adults has more than doubled since the 1980s. The International Diabetes Federation estimates that more than 14 million people in Africa live with the disease and if trends continue this figure could grow to 34 million by 2040.
  2. The increase in diabetes (Type 2) cases in Africa is largely attributed to changing lifestyles. A large percentage of people with diabetes (58 percent) live in cities. Traditional diets are changing to more high-calorie refined carbohydrates and fats which are more readily accessible and affordable than healthier options. Occupational patterns are also changing, leading to physical inactivity and a more sedentary lifestyle.
  3. Most African countries have healthcare systems already struggling to keep up with other illnesses like HIV, tuberculosis, malaria and diarrheal diseases, all of which seem more pressing than diabetes. As a result, Africa has the highest percentage of undiagnosed people (an estimated two-thirds) who are at a higher risk of developing harmful and costly complications. These complications include heart disease, strokes, damage to eyesight, kidney failure and loss of limbs.
  4. Awareness is one of the biggest issues when it comes to diabetes in Africa. Limited awareness about the disease among both healthcare professionals and the general public contributes to the high number of neglected cases or misdiagnosis. Better education about the importance of healthy diets and physical activity is necessary.
  5. Access to affordable insulin is another challenge faced by many diabetics in African countries. Almost a third of diabetics need insulin to treat their disease. While many African countries have health programs that provide more affordable insulin at public clinics, the supply can be erratic, or patients have to travel far to a clinic with supplies. If public healthcare providers do not have insulin, patients are forced to buy more expensive private sector insulin or go without. This is one of the leading causes of the 321,000 diabetes-related deaths every year in Africa.
  6. Insulin is not the only expense. Access to blood glucose meters, test strips and syringes are also essential for diabetes treatment. The high cost of these medical devices, coupled with the treatment of complications due to the disease, increases the burden of disease on patients and healthcare systems.

While the current facts about diabetes in Africa are dire, efforts are being taken to address this challenging disease. Diabetes awareness and treatment programs are being developed by states, civil society and the private sector. For instance, one of the three main manufacturers of insulin, Novo Nordisk, has programs in several African countries to improve awareness about diabetes and to improve the availability and affordability of treatments.

Top Five Neglected Tropical Diseases

Tropical Diseases
Neglected tropical diseases are transmitted diseases caused by parasites, and are usually found in tropical and subtropical regions. They mostly affect people in poverty who live in unsanitary conditions. Most of these neglected tropical diseases can be easily prevented with treatments and vaccinations that are affordable.

Lymphatic Filariasis

More than 1.3 billion people across 72 countries might be at risk for this disease, and more than 120 million people are infected by it. Lymphatic filariasis is caused by infections from parasites called filarial worms and leads to abnormal enlargements of body parts, which causes great pain. The disease is better known as elephantiasis. There has been some success in stopping the spread of the disease by using preventive chemotherapy. The disease can also be treated with a care package that alleviates pain and prevents any more disfigurement.

Onchocerciasis (River Blindness)

The River Blindness disease gets its name from the black flies that are found in fast-flowing streams and rivers. Infections cause blindness and skin disease. Ninety percent of cases occur in Africa, with a lot of cases in Latin America and Yemen as well. Long-term skin damage and blindness can be prevented with a medicine called ivermectin.

Schistosomiasis (Snail Fever)

Schistosomiasis gets the nickname “snail fever” from freshwater snails carrying the disease. Children can be highly susceptible to the disease when they swim and fish in infested waters. Snail fever has spread in a lot of poor areas in Africa because of migrations and population movements, but the World Health Organization has worked to spread awareness and treat infections. The WHO even implemented campaigns to distribute praziquantel, which can be a large-scale treatment of schistosomiasis.

Ascariasis (Roundworm Infection)

Ascariasis is one of the most common neglected tropical diseases, infecting more than one billion people per year and causing 60,000 deaths each year. The disease is caused by a parasitic roundworm called Ascaris lumbricoides. More than one hundred worms can infect a human at a time. The earthworm eggs can be accidentally ingested through contaminated food, water and soil. Some symptoms can be minor, such as coughing, loss of appetite and a fever. In severe cases, it can cause malnutrition, intestinal blockage and pneumonia. There have been companies donating to help fight the disease, such as Johnson and Johnson, pledging to donate 200 million tablets of mebendazole by 2020, and GlaxoSmithKline, donating one billion tablets of albendazole a year.

Trachoma

Trachoma is another eye disease that is much more severe than River Blindness. It is one of the most infectious causes of blindness and affects about 1.9 million people. Trachoma is either spread through physical contact with the eye or nose discharge from other people. Fleets of flies have been known to carry the disease as well. This neglected tropical disease mostly affects women and young children in poor rural areas in Africa and Asia. The World Health Assembly has adopted Resolution WHA51.11 which is geared towards eliminating the disease by 2020.

With continued intervention from governments, NGOs and corporations, these neglected tropical diseases can be effectively targeted and eliminated, ensuring lives of enhanced productivity and prosperity for millions of people around the world.
