How Cell Phones are Helping Us Fight Ebola

fight_ebolaThe Ebola outbreak in West Africa continues remains a major public health concern worldwide. In the face of this tragedy, technology provides great hope in managing the disease and providing aid to individuals and healthcare providers. Many technologies are on the forefront of fighting disaster, but the most valuable tool to fight Ebola is probably in your pocket.

Africa has experienced a boom in cell phone ownership in recent years, which has extended to West Africa. As a result, cell phones are providing patients and families of patients with services such as ebola hotlines. Cell phones also allow health workers to be paid electronically, allow clinics to flag when they’re low on supplies and allow individuals to resolve rumors of ebola by texting local radio stations.

Eric King, an innovation specialist who worked with USAID’s Disaster Assistance Response Team in Liberia, said, “among the technological tools that have amplified the Ebola response, arguably none has been more helpful than the mobile phone.”

And it’s not just helpful for individuals. Cell phone companies collect “call data records,” which manage caller identity and the time of the call, along with being able to identify the customer’s location. These records, held by CDRs, are highly valuable to epidemiologists.

But cell phones have been most valuable in fighting Ebola in the hands of health care workers. The mHero program uses information to bring together people making a difference in coordinating a response to this crisis.

The mHero program brings cell phones together with many services. These services include the iHRIS program, a human resource tracking service used within the health sector of 19 countries, along with UNICEF’s SMS platform and information sharing systems such as OpenHIE and DHIS 2.

The mHero programs bring all of this together to allow key text messages to be sent to heath workers internationally, even in remote areas where there is traditionally less access to cell phone service. Having access to this large database of information allows for messages to be targeted to health workers in relevant locations.

According to intrahealth, mHero is also useful to government officials, who can use it to conduct monitoring processes along with data analysis and surveys. The service, which launched in Liberia in September, represents perhaps a major victory in the fight against Ebola.

Information is power. Cell phones are an accessible technology which provide people worldwide with information. It should be no surprise, then, that cell phones are an incredible source of power in responding to the Ebola crisis.

Recent Trends in Global Public Health Funding

Global_Public_Health

While aid for global public health programs skyrocketed just after the Millennium Development Goals (MDGs) were announced 15 years ago, aid has stalled in the past few years, according to a recent report by the University of Washington’s Institute for Health Metrics and Evaluation (IHME).

The MDGs, a set of eight anti-poverty goals with broad international backing, expire this year. Because of them, there have been significant reductions in child mortality and broad treatment of HIV/AIDS, malaria and tuberculosis in the developing world. However, donors must realize that continued funding is necessary to sustain the progress already achieved and make further improvements in public health internationally.

The report from the IHME found that there was an incredible surge in funding after the MDGs were announced, jumping from 5.4% prior to 2000 up to 11.4%. In the past 15 years, this growth in funding amounted to a total of around $228 billion invested in health-related causes. However, that growth has essentially stalled and, in some cases, reversed—from 2013 to 2014, total spending on health even decreased by 1.6%.

This trend can probably be attributed to waning enthusiasm for health-related aid once the initial excitement of the MDGs died down and their 2015 deadline draws to a close. Additionally, it could be a symptom of more cash-strapped governments seeking to trim their budgets after the 2008 global financial crisis.

While overall funding for health went down between 2013 and 2014, a few national donors did manage to increase their contributions, including the United Kingdom, Australia and Japan. Nongovernmental organizations also modestly increased their funding, including UNICEF, the Bill and Melinda Gates Foundation, and the African Development Bank.

Even modest changes in health aid funding would have a disproportionate impact on certain populations who have differing disease burdens. For example, 84% of funding for the treatment and prevention of HIV/AIDS comes from the United States. A small percentage decrease in funding for HIV/AIDS relief from the United States would have a much greater negative impact than a small percentage decrease from a smaller donor.

The IHME report, by describing flows of global health financing, reveals the need not only to maintain or increase aid but to diversify it also. Katie Leach-Kemon, a co-author of the study, said of HIV/AIDS funding that “diversifying the portfolio of financing sources for this area is crucial for safeguarding the progress made in combating the HIV epidemic.” Vulnerable populations would have access to more consistent aid if funding sources were spread more evenly across a wider variety of donors. That way, if funding trends continue to fluctuate, as they do in the report, those who typically rely on robust health aid programs, such as Ethiopia, Haiti and Kenya, will not find themselves cut off.

Health funding studies like the IHME report serve as excellent roadmaps that describe successes in global public health programs and reveal their shortcomings as well. Clearly, international initiatives with broad support, such as the MDGs, serve to jump start health aid. On the other hand, in the past five years, the incidence of tuberculosis was as high as 13% in some areas, HIV/AIDS as high as 20% and under-5 child mortality as high as 18%. Health aid has made huge strides in the past 15 years, but in order to continue reducing the global disease burden and improve the lives of people all over the world, funding has to be maintained.

Substandard Medications Threaten the Eradication of Malaria 

medications
Health professionals attempting to treat patients with malaria are currently facing another complex obstacle in the developing world: the distribution of substandard, falsified and degraded antimalarial medications.

Drugs classified as substandard are medicines that have insufficient amounts of the necessary active ingredient. In order to effectively kill the bacteria and other harmful organisms thriving inside a malaria patient, the full, prescribed dose of the drug needs to be ingested.

When anything less than the full dose is ingested, these organisms not only continue to survive, but also develop a resistance to the drug entirely. This renders current anti-malaria drugs completely ineffective.

“Poor quality antimalarial drugs are very likely to jeopardize the unprecedented progress and investments in control and elimination of malaria made in the past decade,” according to Fogarty scientist, Gaurvika M.L. Nayyar.

Since the early 2000s, the World Health Organization has recommended artemisinin as the first line of treatment for malaria patients, since “artemisinin and its derivatives are powerful medicines known for their ability to swiftly reduce the number of Plasmodium parasites in the blood of patients with malaria.”

Artemisinin is combined with other supplementary drugs in Artemisinin Combination Therapy treatments in order to effectively assist those diagnosed with malaria. However, these substandard drugs are causing an increase in bacterial resistance to artemisinin treatments, rendering the first line of malaria defense utterly useless.

According to a study done by National Public Radio in 2012, “a third of all anti-malarial drugs taken off the shelf in nonrandom surveys in Africa and Asia were absolutely fake. In about 4,000 samples, there was not a drop of active ingredient there.”

The distribution of these partially active medications has recently been classified as a “global pandemic” affecting the poorest parts of the world, specifically West Africa and Southeast Asia, where drug regulatory systems are weak.

The Centers for Disease Control and Prevention said, “Counterfeiting occurs throughout the world, but it is most common in countries where there are few or no rules about making drugs. An estimated 10 percent to 30 percent of medicines sold in developing countries are counterfeit. In the industrialized world (countries such as the United States, Australia, Japan, Canada, New Zealand, and those in the European Union), estimates suggest that less than one percent of medicines sold are counterfeit.”

On April 20, The American Journal of Tropical Medicine and Hygiene released a special issue, titled “The Global Pandemic of Falsified Medicines: Laboratory and Field Innovations and Policy Perspectives,” which contained a series of 17 papers. Each is written by a different author from a different university or institution, yet all cover the implications surrounding the distribution of substandard medicines throughout the developing world.

According to one of the studies, over 122,350 child deaths were caused by insufficient or partially-active anti-malaria drugs in 2013 alone. This figure represents one-fifth of all deaths caused by malaria.

“These findings are a wake-up call demanding a series of interventions to better define and eliminate both criminal production and poor manufacturing of antimalarial drugs,” Nayyar said.

Education and Healthcare Access in Kenya

Education-and-Healthcare-Access-in-Kenya

I will never forget hearing the story about the woman in Kenya who ran away when a soldier pulled out a condom. She had heard a rumor that if someone tried to use a condom, it meant that they had HIV.

In Kenya, healthcare and education about sex and general health is limited. Moreover, the small amount of health and sex education that does exist is often misguided.

In the past ten years, three people that my family and I were close to died of HIV. All three of them were parents and the breadwinners of the family. On Monday, my mother called to inform me that yet another person that we know is ill, and may be dying of HIV.

According to USAID, around 1.6 million people are living with HIV/AIDS in Kenya. In addition, about 1.1 million children in Kenya are orphans because of AIDS.

People in Kenya with HIV/AIDS, and those at risk, often lack access to healthcare.

In Kenya, healthcare is a constitutional right, but the cost is too high for a majority of Kenyans. In addition to the cost, the closest healthcare facility is often way too far away for poor Kenyans to reach.

According to the World Bank, “only 20 percent of Kenyans have access to some sort of medical coverage.” In April 2014, the Kenyan government launched the Health Insurance Subsidy Program in order to make healthcare more affordable for people in Kenya. While this is a good first step, it does not help the many people who are unable to reach a healthcare facility.

An article by Allianz states that if poor Kenyans living in rural areas are able to seek healthcare, they are often only able to find treatment at a primary care facility. These facilities are often under-staffed and under-equipped, and have limited medicines. One of the three people in my life who died of HIV/AIDs died in a hospital due to HIV-related dehydration. It is possible that he could have been saved by something as simple as an IV if the doctors had known what to do.

Luckily, organizations like USAID and the World Bank are working on treating and preventing HIV/AIDS and giving Kenyans greater access to healthcare.

In 2003, USAID launched the President’s Emergency Plan for AIDS Relief. The program is focused on prevention, treatment and care. These programs have made steps in the past 12 years. For instance, mother-to-child transmission rates have dropped from 28.3% to 8.5%.

However, transmission rates are not the only numbers that have been dropping. Between 2010 and 2013, USAID’s funding to Kenya was cut in half.

HIV/AIDS is continuing to spread in Kenya, and the people who need aid the most are not receiving it. The United States could be doing much more to aid the poor in Kenya. So why is the government decreasing funding, rather than continuing the work that has just begun?

How Coca-Cola Is Helping Deliver Medicines

coca_cola
Coca-Cola products reach every corner of the world while essential medicines do not. ColaLife, a UK charity, noticed this and decided to make a change. ColaLife uses Coca-Cola to open up the private sector supply chain to deliver affordable and effective medicines.

ColaLife produced the Kit Yamoyo, an anti-diarrhea kit. Diarrheal diseases cause life-threatening dehydration, which is the second leading cause of death in children under the age of 5 in developing nations. Each year, it takes the lives of 760,000 children, even though it’s curable.

The problem is that these children do not have access to the cure, which is what ColaLife sought to solve. The Kit Yamoyo contains Oral Rehydration Salts (ORS), soap, and zinc, which act as a cure. The package itself acts as a measuring device for water needed to mix up the ORS and zinc, and can also be used as a storage device as well as a cup.

The Kit Yamoyo has a v-shaped cup to easily fit into the Coca-Cola delivery crates. As a compact, low-cost product, the Kit Yamoyo piggybacks Coca-Cola’s supply chain to reach remote areas. It is a symbiotic relationship: Coca-Cola products continue to reach and get sold in remote areas, while the consumers gain access to more medicines than ever before.

The kits themselves are sold with Coca-Cola products. As the kits make their way out to the remote areas, the demand for them becomes greater. It’s a positive situation for everyone involved: Coca-Cola products are sold, the retailer makes a profit, and the consumer gets the medicine they need to help their children.

With enough funding, the Kit Yamoyo will have a big impact. It will widen vaccine coverage in remote areas and reduce death rates caused by dehydration and malnutrition. It will also encourage an increased investment in training and help health workers reduce child mortality rates. ColaLife has proven that the supply chain is just as important as the medicine itself.

Global Hunger Affects Fewer than 800 Million People

global_hunger

Currently, the number of people who face hunger is around 750 million people. The number of people living in hunger has been reduced by about 167 million people in the past 10 years. In the past year alone, the number of hungry people dropped by 10 million people.

This is incredible progress!

One of the main focuses of the Millennium Development Goals is to eradicate global hunger. Global hunger has dropped considerably, and this is a moment to recognize all that has been accomplished.

In South America, less than five percent of the population faces hunger. The number of hungry people has dropped by 50% in the past 25 years. Central and South East Asia, as well as Northern Africa, have seen a drop in the number of hungry individuals.

However, 44 percent of countries did not accomplish the Millennium Development Goal of reducing hunger by 50 percent in the last 15 years. South Asia still has 281 million people who suffer from hunger. In Sub-Saharan Africa, 23 percent of people do not get enough food.

Political instability in Sub-Saharan Africa may contribute to why hunger is still a problem. Twenty-four countries in Africa are currently experiencing food crises. This number is up from the 12 countries who were experiencing food crises in 1990.

Recently, bountiful food harvests and low oil prices have made the price of food drop considerably. These factors could have played a role in why hunger has been dropping.

Beyond economic growth, countries also have to focus on inclusive growth. For example, social investments, such as cash transfer programs, employment projects, food distribution schemes, healthcare and education could all reduce the number of hungry people.

Food is a basic necessity. It is extraordinary news that global hunger has dropped below 800 million. We need to continue to prioritize eradicating world hunger. If we continue progressing in this way, it is conceivable that world hunger could be eliminated.

What Hillary Clinton Means For Women’s Health Worldwide

Hillary-Clinton-Women's-Health

In April of this year, Hillary Clinton announced her candidacy for president. As a strong democratic nominee with a lot of political capital, she has the power to raise big money and advocate for issues on her platform.

According to her website and her voting record, she is an advocate for small business and defining America’s core values. Many see her as a strong candidate for the election next year.

However, unlike her last campaign, Clinton seems to be focusing more on women’s issues.

In 1995, Clinton gave a speech in Beijing entitled, “Women’s Rights Are Human Rights” to the U.N.’s Fourth World Conference on Women. At the time, Clinton was First Lady of the United States. In the speech, Clinton spoke of the continual rape of women during armed conflicts and the act of silencing women and girls around the world. She declared that women’s rights must now be seen as human rights and solved.

Since the 90’s, Clinton has seemed to not focus on women’s issues or place them at the focal point of her 2008 election.

However, this round, she seems to be doing the opposite. Before announcing her candidacy in a speech at Georgetown, Clinton told the audience that women’s rights are not only a responsibility for women, but also men.

At her first major campaign event in June of this year, Clinton seemed to emphasize her support for women’s issues. She supports a women’s right to choose and have easier access to contraceptives.

Clinton has proved herself to be an advocate for women domestically, but what about abroad?

Clinton does not seem to shy away from economic aid to developing countries. In 2012, Clinton visited Africa, promising U.S. assistance to revitalize African economies. Although many attacked her for attaching so many contingencies onto the package, she does want to help.

Combining her commitment to providing assistance to impoverished nations and her advocacy for women’s rights, she would be a tremendous help to women’s health abroad.

Under her watch, we could see a real attempt to repeal the Helms amendment and provide access to family planning tools. Because of her commitment to women domestically, she would support women’s access to education abroad.

Although the campaign trail is long, her commitment to women and impoverished nations would mean great things for women being affected by the lack of access to a proper education, birth control and water.

How Malawi’s Male Champion Model Program is Fighting HIV

Male Champion Model
Worldwide, 34 million people are living with HIV, including 3.3 million children. In the African nation of Malawi, 910,000 citizens out of a population of 15.9 million have HIV. Around 170,000 are children, and children account for 16,000 new infections annually. It is the leading cause of death among adults in Malawi and contributes to the country’s low life expectancy of 54.8 years.

Each year, thousands of babies in Malawi contract HIV through mother-child transmission. This can occur during pregnancy, labor, delivery or breastfeeding. Children with HIV get sick more often and more severely than children without HIV, and they struggle to fight common pediatric infections. In developing countries, they have a higher risk for tuberculosis, diarrhea and respiratory illnesses, all of which can be a death sentence if they lack access to effective healthcare.

A baby born to a mother who is HIV positive has a 15% to 45% chance of contracting HIV if there is no medical intervention. However, this rate drops to 5% with intervention. Malawi’s Ministry of Health must encourage expecting parents to get tested before the mother gives birth in order to provide appropriate care and prevent the baby from contracting HIV.

In 2012, the Ministry of Health worked with UNICEF to launch the Male Champion Model (MCM) program. Before the MCM, it was incredibly rare for men to be involved in their wives’ healthcare, even if she was pregnant. Furthermore, many women avoided being tested for HIV out of fear of being abandoned by their husbands or discriminated against in society if the results were positive. The MCM trains “male motivators” to reach out to other men in their communities to encourage them to accompany their wives to get tested.

So far, the program has trained 3,400 “motivators” in six districts of Malawi. They visit households in their villages each day to discuss the importance of HIV testing with couples. Now it is increasingly common for couples to get tested together, and in one year, the country has seen a huge jump, from 0% to 86%, in men participating in antenatal services. When women know their status, their healthcare providers can give them anti-retroviral drugs to reduce the risk of transmitting HIV to their child.

Over the past decade, Malawi’s government has focused on decreasing the nation’s HIV rates, and the MCM is just one part of these efforts. They have expanded voluntary HIV testing and counseling, promoted condom use, increased the distribution of condoms, started a mass media campaign to raise awareness about prevention and educating young people about HIV.

These initiatives have led to some progress. In 2003, 14% of the population had HIV, and by 2011 that number had dropped to 10%. Also in 2003, 100,000 new infections were occurring annually, but that number had dropped to 46,000 new infections by 2010. Clearly, there is still a long way to go toward stamping out HIV in Malawi, but the MCM program has spared many children from the struggles of surviving with HIV.

Canada’s Missing Link: Health and Housing

Canada-Housing-Health
For quite some time, Canadian health officials have conducted thorough research to trace the cause of unstable housing. Now, officials have sorted out the missing link: bad health.

A 2005 published study by researcher Liz Evans presented the connection shared between HIV-sufferers and occupied hotel residency. At the time of the research, Evans illustrated the fact that 80% of Canada’s single-rooming units in hotels (estimated at 6,000) were located in Canada’s poorest Downtown Eastside, in which rooms were frequently occupied by those suffering from HIV.

One solution was to remove the hotel units; however, Evans knew that such an approach would result in “catastrophic” consequences. The analyst went on to state that the units were not “evils,” but rather an escape for HIV-sufferers who live in fear caused by social rejection.

Years would progress with minimal updates that validated Evans’ work until 2007, when TimesArgus.com broke a story on the 2010 Vancouver Games’ organizers deliberating if low-income housing should be moved elsewhere before the event. Although the organizers initially told the public that housing rights would be “respected,” over 700 low-income residents were displaced that same year in addition to inexpensive housing being converted into tourist venues. This action ignited strong backlash from a league of protestors.

The incident served as a rubric sheet for medical analysts to test theories that have longed signified a potential connection between housing issues and the trend of bad health yielded by the likes of street-involved youth.

Unearthed by the Public Health Agency of Canada, street-involved youths typically have a background of family abuse and a violent home environment. The aftermath follows with subjection to low income, low education, and lack of support or inability to pay first/last month’s rent; all of which are triggers to unstable housing.

Once housing becomes an issue, the vulnerability of infections caused by negative coping systems, such as drug use or unprotected sex, serves as a high risk.

In studying further developments, lead researcher C. Kim went on to run tests involving Vancouver-native drug users and non-drug users. Based on the test results, Kim discovered that active drug users were hepatitis C viral-carriers and singled out unstable housing as the prime connection.

With these results, varying researchers revisited the work done by Evans, who attempted to signify a connection involving HIV-sufferers and extreme occupancy within hotel units. It was in 2014 that analysts determined that the significant increase in emergency department-styled housing was being led by HIV-sufferers.

As conducted in Evans’ work, researchers indicated that those residing in the housing feared social backlash, further contributing to poor health caused by guilt and depression. In both the study and a separate one occurring one year later, analysts conclusively noted that like street-involved youths, unstable housing holds a poor-health effect on HIV-sufferers, where potential enablement of guilt, depression and drug use patterns pose as big risks.

So what exactly is being done to aid the problem?

For street-involved youths who have endured a brutal history, several intervention programs have been established to help those in need. Other establishments like Calgary-based Infinity Project provide youths with a permanent home in a community of their choosing, equipped with support and affordable options to secure them a better life. Similarly, support centers are urged, for those suffering from HIV, to decrease health-care costs and to minimize health problems relating to depression.

As positive networks continue to decrease the rate of unstable housing, optimism for more awareness of the issue comes with wishful thinking of the conflict fading away.

Report Uncovers Decline of Global Health Funding

global_health_funding_decline

According to a new report, countries around the world contributed 1.6% less to global health projects in 2014 as compared to 2013. This is only the second time in the past 15 years a reduction in funding has been documented.

The report, published by The Institute for Health Metrics and Evaluation in Seattle, shows that while global health funding grew by 5.4% annually in the 1990s and increased to 11.3% annually from 2000-2010, it stalled around a year later.

Overall, the world has contributed $227.9 billion to global health funding in poorer countries since the turn of the century, when the United Nations revealed its Millennium Development Goals.

The eight goals, which focus on providing monetary funding to pressing global issues, led to a surge in global health funding.

The largest donor has consistently been the United States, which gave $12.4 billion last year toward the treatment and prevention of AIDS and malaria in developing countries.
However, only three nation’s governments increased overall funding between 2013 and 2014: the United Kingdom, Australia and Japan.

Specifically, funds allocated to improving maternal health around the world decreased by 2.2% and supplies used for the treatment and prevention of tuberculosis were cut by 9.2%.

In addition to revealing the decrease in funding for global health projects, the report also gives insight into disease funding. It shows that some treatments and programs are favored over others.

For example, last year, over $3 billion was allocated toward vaccines for children, over $1 billion was spent on children nutrition initiatives, and $778 million was put toward family-planning projects.

In contrast, only $164 million was spent addressing mental health issues and only $31 million was used for anti-tobacco programs.

David Molyneux, Peter Hotez and Alan Fenwick are three scientists who became frustrated that certain treatments and programs receive more funding than others. Specifically, the three wanted the world to know about 17 largely ignored diseases in the world’s poorest countries.

These diseases can result in blindness, deformed limbs and stunted growth, but are ignored because they have disappeared from the developed world.

With 1.4 billion people suffering from these illnesses, which include onchocerciasis, lymphatic filariasis and leishmaniases, the scientists decided to stimulate awareness about them by coining the term “neglected tropical diseases.”

Molyneux and Hotez first used the term at a World Health Organization (WHO) meeting in Berlin in 2003 to “market” the diseases to politicians and private foundations. It was approved at another WHO meeting the following year, which was also in Berlin.

As a result, the Department of Control of Neglected Tropical Diseases was formed, and since 2006, around a billion dollars has been pledged by government and aid organizations to the fight against neglected tropical diseases.

Pharmaceutical companies are also donating 1.4 billion treatments of the diseases each year, resulting in 700 million people being treated in 2014.

In addition, last month Dr. Matshidiso Moeti, who directs WHO operations in Africa, announced a plan to create an entity with the sole purpose of directing work related to neglected tropical diseases. This is just one part of efforts by the international community to rid the continent of some of these diseases within the next five years.

While some treatments and programs are favored over others, people like Molyneux, Hotez and Fenwick are giving a voice to those in developing countries suffering from largely ignored illnesses such as the neglected tropical diseases.
