Noncommunicable Illnesses Top List of Major Diseases in Grenada


When working to eliminate poverty, understanding public health concerns in regions such as Grenada is critical. Communicable diseases such as measles, polio and smallpox on this Caribbean island are less common today than they once were as a result of vaccinations and other public health strategies. Noncommunicable and preventative diseases, however, have been of more concern to health workers and government officials in the country.

The World Health Organization (WHO), the Pan-American Health Organization (PAHO) and the Institute for Health Metrics and Evaluation (IHME) have found that the most prevalent diseases in Grenada are, in no particular order:

  • Cancer is a leading cause of death in Grenada. Roughly three percent of Grenadians die from this disease yearly. Prostate cancer is especially deadly, accounting for about 17 percent of those deaths. Local doctors and organizations have strived to raise awareness and money for the Grenada Cancer Society. The annual Walk for the Cure, for example, is hosted by the First Caribbean International Bank and helps give assistance to cancer patients in need.
  • Respiratory diseases and infections are also among the leading causes of death and disability in Grenada. During a 2010 PAHO study of discharge data at St. George’s General Hospital, respiratory illnesses made up 4.9 percent of visits. About 1.5 percent of the population dies yearly from lower respiratory infections, a rate that is significantly higher than that of similar countries. Risk factors include air pollution and tobacco smoke.
  • Cardiovascular diseases are very common in Grenada, and ischemic heart disease is the most common form found in the country. IHME estimates that 2.4 percent of people die yearly from this form of heart disease. And, although fewer people die from it annually, ischemic heart disease still remains a leading cause of death. Those with poor diet or physical inactivity are more at risk of cardiovascular disease. The Grenada Heart Project is critical in raising awareness and helping the sick.
  • Hypertension is among the diseases in Grenada that adults are most commonly diagnosed with. The morbidity rate of hypertension for adults ages 20 to 59 is 7.25 percent and for the elderly is 48.7 percent. In the PAHO hospital study mentioned above, this health problem led to 12.9 percent of hospital visits. Poor diet and physical inactivity are risk factors for hypertension. To reduce the risk of hypertension, the Grenada Food and Nutrition Council recommends better lifestyle choices such as eating healthier, being more physically active and quitting smoking. The Grenada Heart Project also focuses on this issue.
  • Diabetes is another disease that adults are most commonly diagnosed with. Diabetes affects about 9.4 percent of adults ages 20 to 59 and 27 percent of the elderly. About 1.7 percent of Grenadians die from this disease yearly, which is significantly higher than that of similar countries. The PAHO hospital study found that diabetes accounted for 27 percent of doctor’s visits. The risk of this disease has been seen to increase with age and if previously diagnosed in the family. Again, poor diet and physical inactivity are risk factors for diabetes. The Grenada Diabetes Association is a key decision-maker working to decrease the death rates and prevalence of diabetes in the country.
  • Cerebrovascular disease is another leading cause of death and disability in Grenada. Roughly two percent of the population dies every year from this illness, another mortality rate that is significantly higher than that of similar countries. As with many of the above diseases, poor dietary choices and physical inactivity increase chances of cerebrovascular disease.

Many health workers hope that, by addressing obesity, a preventative condition that has become more widespread in the country, they can decrease the prevalence of noncommunicable diseases in Grenada such as diabetes, hypertension, heart disease and cerebrovascular disease. One way to combat these health problems is to focus on eating habits and physical activity, both critical factors that affect obesity.

Fighting these diseases in Grenada and around the world has not and will not be easy, but people and organizations are continuing to work together to raise awareness for prevention, treatments and cures.

Top Diseases in El Salvador


Coronary heart disease is the leading cause of death in the relatively small country, which has less than seven million citizens. The next leading causes of death include influenza, pneumonia, kidney disease, liver disease and lung disease. El Salvador has a relatively high number of healthcare workers but is still not able to meet the needs of the population with its current healthcare system and the unequal distribution of healthcare workers at different levels of service.

It is important to note that the top diseases in El Salvador and the top causes of death are not the same. Violence against citizens and road traffic accidents are among the top ten causes of death in El Salvador.

Regarding infectious diseases in El Salvador, currently, the Zika virus is still a significant risk to pregnant women in or traveling to El Salvador. The primary method of contraction of this disease is through mosquito bites and sexual exposure. However, these mosquitoes cannot usually survive at elevations above 6,500 feet.

Though not everyone who contracts Zika gets sick, sometimes mild symptoms can last for several days. Occasionally Guillain-Barré syndrome (GBS) will accompany Zika virus, which entails muscle weakness and paralysis for a few weeks to several months. Research suggests the two are associated.  However, it remains unconfirmed due to the minimal amount of people with Zika virus that also contract GBS.

Hepatitis A and Typhoid can both be contracted through contaminated food or water in El Salvador though they are not among the top causes of death in the country. The risk of malaria contracted through mosquitoes is low, and is preventable with bug sprays.

Though El Salvador has struggled to provide adequate healthcare to its citizens in the past, the Ministry of Health and Social Welfare (MSPAS) has made strides in changing things. Most pressing is the disparity between public and private healthcare systems.

Fighting Common Diseases in Guatemala

Fighting Common Diseases in GuatemalaCommon diseases in Guatemala include malaria, bacterial diarrhea, and HIV/AIDS. These diseases are common throughout this area of the world. Malaria spreads through mosquitoes, which are common in Central American countries, putting inhabitants at a greater risk for the disease. People in these countries may live in areas without proper sanitation, consequently causing a high prevalence of bacterial diarrhea. HIV/AIDS is common in Guatemala partially due to a lack in sexual education programs.

In certain areas of Guatemala, malaria rates are higher than in other countries. In 2015, there were 6,834 cases of the disease. Since 2005, the government has been fighting the disease with additional funding from the Global Fund. The goal is to nationally eliminate malaria by 2020. In order to avoid bacterial diarrhea, doctors advise individuals to practice good hygiene when using the restroom, maintain clean water, and properly clean food.

Lastly, Guatemala created a comprehensive sexual education plan to prevent the spread of HIV/AIDS and other sexually transmitted diseases. However, a survey in 2015 showed that only 7 percent of students learned all of the intended points in the program. Another issue with this program is that out of classrooms that taught students about condom usage, 43 percent did so incorrectly. Since STDs and STIs are a common problem in Guatemala, people are pushing for improvement of the sexual education program through better instructor training or a complete reconstruction.

These are a few of the most common diseases in Guatemala. Travelers are warned against malaria and bacterial diarrhea. Additionally, HIV ranks number nine in the top 10 causes of death in Guatemala. Through better education and prevention, the prevalence of these common diseases in Guatemala can significantly drop and the well-being of the people will improve.

Top Diseases in Bulgaria


Located off the coast of the Black Sea in Southeastern Europe and nestled just between Romania and Turkey lies the nation of Bulgaria, a country only slightly larger than the state of Tennessee. Although Bulgaria’s average life expectancy has been climbing steadily, the country still has one of the shortest life expectancies in the European Union at 74.5 years, coming in just ahead of Lithuania and Latvia. Here are some facts about the top diseases in Bulgaria:

Cardiovascular Diseases

Heart diseases–disorders of the blood vessels and heart–are the deadliest of the top diseases in Bulgaria. Currently, such diseases are the cause of over 60 percent of all deaths in the country.

According to a 2015 report published by the Institute for Health Metrics and Evaluation, the three most fatal heart diseases of the previous decade in Bulgaria were ischemic heart disease, cerebrovascular disease and hypertensive heart disease, which were the first, second and third most deadly diseases in Bulgaria respectively. Since 2005, deaths from ischemic heart disease had become 1.9 percent more prevalent, while deaths caused by hypertensive heart disease had become 13.2 percent more prevalent. Deaths due to cerebrovascular disease, on the other hand, had decreased by 1.3 percent.

The World Heart Federation lists controllable risk factors of heart diseases to be, among others, tobacco exposure, harmful consumption of alcohol, physical inactivity and obesity. In 2009, Bulgaria addressed the country’s high prevalence of heart diseases by participating in World Heart Day, providing free cardiology exams across the country.

Alzheimer’s Disease

Following the formerly listed heart diseases, Alzheimer’s disease is the fourth most fatal of the top diseases in Bulgaria. Alzheimer’s disease, a form of dementia, is a degenerative brain disease in which protein deposits abnormally build up in the brain and, as of 2015, death by Alzheimer’s disease in Bulgaria had become 27.8 percent more common than in the previous decade. According to the World Health Organization, the disease is now the cause of 26.2 percent of all deaths in the country.

Since January 2014, a national policy plan to address dementia in all its forms has been in final review. As of July 2016, there was no finalized national dementia strategy in Bulgaria to address the recent rise in Alzheimer’s disease.

The top diseases in Bulgaria have only just begun to be addressed domestically. With the continuation of direct policy changes and implementation of preventative care, Bulgaria hopes to see reduced instances of heart diseases and Alzheimer’s disease, ultimately increasing their life expectancy.

Combating the Most Common Diseases in Thailand

Common Diseases in ThailandWith places like Bangkok and Khao Yai National Park, Thailand has become a very popular tourist country. In 2016 alone, the country with a population of more than 68 million people hosted close to 33 million visitors. Alongside its many attractions are some issues, including that diseases in Thailand are a persistent problem. Here are three common diseases in Thailand.

3 Most Common Diseases in Thailand

  1. Dengue: Dengue is a viral disease that Aedes aegypti mosquitoes transmit. Once someone is infected, they become a carrier. There are four strains of the virus. Dengue mostly impacts people in tropical climates. Symptoms include high fever and pain in joints, in muscles and behind the eyes.There is currently no cure. It is recommended to seek professional medical care when experiencing symptoms.According to the World Health Organization, “the America, South-East Asia and Western Pacific regions are the most seriously affected” by dengue. The WHO reports 50 to 100 million dengue cases annually. There is now a vaccination for the disease.
  2. HIV/AIDS: HIV is a sexually transmitted infection that weakens the immune system by destroying helper T cells. According to UNAIDS estimates, 440,000 Thai people were living with HIV in 2015.While there is no cure for HIV, there is a treatment known as antiretroviral therapy (ART). ART helps those infected and can even prevent the development of AIDS, which is the last stage of the infection. With the approval of the National AIDS Committee, Thailand is following a plan aimed at eliminating HIV/AIDS in the country by 2030.
  3. Zika Virus: As with dengue, Aedes aegypti mosquitoes spread the Zika virus. It can also be sexually transmitted. According to Reuters, Thailand had around 200 Zika cases from January to September 2016, from January to September. Zika virus is known to cause deformations in newborn babies. For this reason, it is suggested that pregnant women stay away from places where it is prevalent, including Thailand.The people of Thailand are doing what they can to fight Zika virus. The Centers for Disease Control and Prevention trained laboratory workers on how to detect it. There are also surveillance systems that monitor diseases in Thailand, including the Zika virus. There is currently no cure for the Zika virus, but there are tests on a vaccine underway.

These are all presently common diseases in Thailand, but there is significant research being conducted to reduce and eliminate their impact. For now, doctors will continue to assist those affected until their cures are found.

4 Common Diseases in Laos


Laos is a landlocked country in Southeast Asia. The Mekong River runs through the mountainous terrain of the county and provides food, a means of transportation and hydroelectric power. Many areas of the country have poor sanitation and lack accessible healthcare. Four common diseases in Laos are Dengue Fever, respiratory infections, ischemic heart disease and diarrheal diseases.

4 Common Diseases in Laos

  1. Dengue Fever: Dengue fever is a mosquito-transmitted virus. The Aedes Aegypti mosquito transmits the disease and breeds in stagnant water, often in man-made containers. Symptoms of dengue fever are a high fever, headache, muscle and joint pain and eye pain. Around two percent of cases advance to dengue hemorrhagic fever which can be fatal. The number of dengue fever cases and deaths is increasing as a result of urbanization and lack of adequate sanitation. Dengue is the fourth leading cause of death in Laos. The government has run many campaigns to encourage people to remove standing water from their land. This eliminates the breeding areas of mosquitoes that spread the disease.
  2. Respiratory Infections: Lower respiratory infections are also very common in Laos. Influenza and pneumonia cause 13 percent of deaths in Laos. These diseases are most prevalent in June and July because of the rainy season and subtropical climate. Many people in rural Laos do not have access to vaccines. Pregnant women and children have a higher risk of dying from these illnesses. Household pollution contributes to the prevalence of these diseases in Laos. Alternative stoves and heating appliances could help reduce pollution in the home and prevalence of respiratory infections.
  3. Ischemic Heart Disease: Also known as coronary heart disease, ischemic heart disease is another of the most common diseases in Laos. The primary causes of this disease in Laos is dietary risks, high blood pressure, smoking and household air pollution. The number of ischemic heart disease cases is increasing as a result of increasingly poor diets in urban areas. The incidence of heart disease has increased by 33 percent from 1990 to 2010. There is high mortality for this disease in Laos because people do not recognize warning sign of danger or seek necessary medical care. In order to decrease the mortality of the disease, Laos needs to first increase education so that people know when to seek help. Then Laos needs more small health clinics which people can access easily when they feel symptoms.
  4. Diarrheal Diseases: A variety of diarrheal diseases is also very common in Laos. Diarrhea is most deadly in children under five and can be fatal because it causes extreme dehydration. Children can face impaired physical and cognitive development if they survive. Ingesting contaminated food or water causes children to contract this disease. Risk factors for these diseases in Laos are air pollution in the house, being underweight as a child and suboptimal breastfeeding. Research recommends education campaigns in elementary level schools; these will reach a large number of children and these kids can share what they learned with their families. In addition, mothers should breastfeed their children up to two years to improve their children’s nutrition.

The common diseases in Laos are caused by some overlapping features. Laos’ health infrastructure is very small. During the rainy season, roads become inaccessible and people become isolated in their villages without any medical attention. In addition, household pollution contributes to both respiratory infections and diarrheal diseases. Finally, education campaigns focused on transmission and early warning signs are very important.

Major Diseases in Luxembourg in Line with Global Trends


According to the 2014 Euro Health Consumer Index, Luxembourg ranks eighth in Europe for comprehensive healthcare. This makes sense, given the fact that Luxembourg is the wealthiest country in the EU. Even so, Luxembourg still faces diseases that threaten its citizens. This article examines the most major diseases in Luxembourg and what measures have been taken to advance patient care and lower mortality rates.

Most prevalent of the major diseases in Luxembourg is cardiovascular disease. According to the statistics portal funded by the Government of Luxembourg, in the year 2014, cardiovascular diseases caused approximately 31.2 percent of deaths. Ischemic heart diseases, as well as other forms of heart disease such as heart failure and cardiac arrest, were the leading causes of death within this category.

Cancer causes 30.6 percent of deaths in the country. Cancers of the digestive system accounted for the highest rate of death in this category, followed closely by cancers of the respiratory system. These two cancers alone cause 52.5 percent of cancerous deaths in Luxembourg.

Respiratory diseases account for 6.97 percent of deaths. Chronic lower respiratory diseases, such as asthma, bronchitis, emphysema, influenza and pneumonia result in the most deaths, 76 percent, within this category.

The top diseases in Luxembourg align with global health trends. The World Health Organization found that cardiovascular diseases are the most deadly diseases all over the world, contributing close to 15 million of the 54 million deaths in 2015.

Luxembourg’s government has taken steps to combat some of these diseases in an effort to lower mortality rates. For instance, the Ministry of Health has implemented a four-year national cancer plan from 2014-2018. This plan is designed to develop cancer prevention methods and improve recovery processes.

Like so many other countries around the world, Luxembourg has made it its mission to find a way to not only combat the major diseases but also to better the lives of its citizens.

Major Diseases in Moldova, One of Europe’s Poorest Countries

Diseases in Moldova
The Republic of Moldova is a parliamentary republic that has implemented an ambitious economic reform program. Agriculture dominates the economy, and the country depends on imports for energy needs. Moldova remains the poorest country in the World Health Organization’s (WHO) European region, although it has made significant progress in economic growth. It had an estimated per capita gross national income of $1810 USD in 2010, according to the World Bank. Life expectancy estimates are two to five years higher than the other countries in the Commonwealth of Independent States (CIS). Most deaths are a result of diseases in Moldova. Both communicable and noncommunicable diseases have been increasing steadily since the country’s independence in 1991.

The most common causes of death in the country are circulatory system diseases, followed by cancer and digestive system diseases. Most of the deaths caused by diseases in Moldova are related to heavy alcohol and tobacco use, although chronic liver disease and cirrhosis rates have decreased over the last five years.

Key challenges in the fight against diseases in Moldova also include HIV/AIDS and tuberculosis. The prevalence of tuberculosis has been rising since 1990 and has more than doubled to date, reaching 182 per 100,000 people. The most dramatic rate increase is in children.

The deadliest risk factors for diseases in Moldova are dietary risks, high systolic blood pressure and high body mass index. Lesser risks include tobacco smoke, alcohol and drug use and high fasting plasma glucose.

While Moldova has quite a bit of work to do, being number one in death rates due to liver diseases, number five in prostatic hypertrophy and number seven in both coronary heart disease and congenital anomalies, it is on the road to better lives for its citizens. It is pushing to reduce poverty, with many Millennium Development Goals being developed and maintained. The country is also working to develop agricultural sustainability and many different ways of importing medicine and products that will help with rates of diseases in Moldova.

Prevention of Waterborne Diseases in Developing Countries


Water is an easy traveling venue for many small particles and microorganisms. Many developing countries suffer from poor prevention of waterborne diseases. Much of the water in areas with poor water filtration is filled with particles ranging from natural silt and oils to human waste and animal feces. These particles infiltrate a community’s water system, including the drinking water, leading to easy infection. Eighty percent of all diseases in developing countries are linked to poor water and sanitation conditions. Within developing countries, 1.8 million people die each year from waterborne diseases. Of these deaths, over 90 percent are children under the age of five.

Waterborne diseases are easily transmitted through unclean hands, uncovered food and contaminated water. The bacteria and worms that live in the contaminated water can easily be prevented. However, in a low-income country where health care is dismal, infections become detrimental to a person’s life. On top of living in an area with poor sanitation facilities, children living in these areas usually suffer from malnutrition. This leads to a weakened immune system, leaving them unable to fight off the infections caused by waterborne diseases.

Many steps are taken to aid in the prevention of waterborne diseases in developing countries. The easiest way to prevent diarrhea diseases is simple sanitation actions. This includes boiling water to disinfect it, washing hands frequently and cleaning dishes. On a small scale, these actions are incredibly helpful to reduce the risk of infection. On a large scale, much more must be done to prevent waterborne diseases. However, most developing countries do not have access to the necessary sanitation products such as soap. They also lack access to water systems that can easily filter out bacteria and waste.

Organizations such as Clean the World and The Water Project have dedicated their resources to make it possible to prevent waterborne diseases in low-income areas and provide access to soap, clean water and sanitation facilities. Clean the World distributes hygiene products, especially soap, to low-income areas that normally do not have access to such goods. This is done through recycling old, barely-used hotel soap and re-purposing them to developing countries. The Water Project combats diarrhea diseases by going directly to the source. It is an organization that brings clean water filtration to developing countries by building wells, rainwater catchment systems and spring protections. Clean water and sanitation is the key to preventing waterborne diseases.

10 Facts About Cholera: What It Is and What It Does


Vibrio cholera is the type of bacteria that causes cholera, a diarrheal illness with symptoms that do not often appear in those suffering infection. Sometimes, the disease is more severe than others, which is why it is important to learn about it. Here are 10 facts about cholera.

10 Facts About Cholera

  1. It can take up to five days for an infected individual to display symptoms, but according to the World Health Organization (WHO), cholera can be fatal within a few hours of infection.
  2. Cholera was originally found in the Ganges delta in India during the 19th century.
  3. There have been six pandemics in which cholera spread to each continent.
  4. Warm and salty coastal waters are very conducive to growth of cholera.
  5. Cholera is transmitted through contaminated water, so impoverished and crisis-ridden areas are the highest risks for outbreak, according to the WHO.
  6. The Center for Disease Control and Prevention (CDC) estimates that there are 3-5 million cases of cholera each year and over 100,000 annual fatalities resulting from infection.
  7. The CDC estimates that one in 10 infected individuals will become severely ill with symptoms including diarrhea, vomiting and leg cramps.
  8. Good hygiene practices, like boiling water or drinking only bottled water and proper hand washing can help prevent cholera infection.
  9. There is an oral vaccine that is not routinely recommended. There are two others, but they are not available in the U.S. at this time.
  10. Treatment focuses on replacing fluids lost through diarrhea. According to the CDC, when treatment is given properly in a timely manner, less than one percent of patients die.

These 10 facts about cholera show that preventative measures that can be taken to reduce chances of infection. They also enumerate the symptoms to look out. The CDC is currently investigating outbreaks to learn more about cholera, and the U.S. Agency for International Development provides countries with water and sanitation supplies to help prevent spread. The above facts can shed some light on what these organizations are doing to combat cholera and why what they are doing is important.
