Uganda Declares End Of Ebola Outbreak

“Uganda is now free from Ebola, the Health Ministry said, two months after an outbreak of the deadly virus killed at least 16 people,” Reuters reports. “‘The Ministry of Health has … officially declared an end of the Ebola outbreak that broke out in Kibaale district in July. This follows completion of the 42 days of the post-Ebola surveillance countdown period which is a prerequisite of the World Health Organization,’ it said in a statement late on Thursday,” the news service writes. “Uganda has suffered several Ebola outbreaks before, the biggest in 2000, when 425 people were infected by the virus and more than half of them died,” Reuters notes (Biryabarema, 10/5).

Scientists Use New Communications, Research Technologies To Quickly Identify, Contain Microbes

Since the outbreak of what became known as SARS, or severe acute respiratory syndrome, 10 years ago, scientists have been quick to identify and contain new viruses, which they attribute to improved communication among researchers and from the general public, NPR’s “Shots” blog reports. In addition to the Internet and social media, the International Health Regulations, which went into effect in 2007, “require countries to report disease outbreaks right away to the World Health Organization,” according to the blog. “Better communications aside, the world has another big advantage over the SARS era,” as the genetic sequencing of new pathogens can be determined quickly, rather than over a period of months, the blog writes, noting, “Knowing the genetic sequence gives researchers a lot of clues about where the virus may have come from” and “also has enabled them to devise a quick and reliable diagnostic test, plus a confirmatory test, so doctors can tell if an acutely ill patient is infected with the new virus or something else” (Knox, 10/3).

New SARS-Like Virus Not Spread Easily, WHO Reports

“A new strain of a potentially deadly virus related to SARS, which has killed one man in Saudi Arabia and left a Qatari man critically ill in London, does not appear to spread easily from person to person, the World Health Organization says,” according to the New York Times (Santora, 9/29). “To ensure an appropriate and effective identification and investigation of patients who may be infected with the virus, without overburdening health care systems with unnecessary testing, WHO issued a revised interim case definition Saturday on its website,” Xinhua reports (9/30). “On Saturday, the health organization, which was rushing to develop a diagnostic test, said that doctors should test for the virus only if the patient is severely ill,” the New York Times states (9/29). “But [the agency] added anyone who has been in direct contact with a confirmed case and who has any fever or respiratory symptoms should also be tested,” Reuters notes (Kelland, 9/29).

Chinese Innovations, Resources Could Help Create New Global Health Products

In this post in the Bill & Melinda Gates Foundation’s “Impatient Optimists” blog, Christine Rousseau, a program officer at the foundation, describes the importance of diagnostics in HIV/AIDS and tuberculosis (TB) care and treatment and writes, “This brings me to the tremendous role that China’s entrepreneurs can play as partners in global health. China is a country with a huge capacity for innovation as well as the resources required to create new products. We believe that China is uniquely positioned to develop new health technologies that can benefit people in the developing world faster and more effectively than product developers elsewhere.” She notes “the HIV and TB teams of the Bill & Melinda Gates Foundation will be presenting the business case for a new generation of diagnostics to Chinese researchers, product developers, and investors at the China Diagnostics Conference in Shanghai on September 25 and 26” (9/24).

Global Health Funding Cuts Threatening Fight Against HIV, TB In Eastern Europe, Central Asia, NGO Report Says

The fight against HIV and tuberculosis (TB) in Eastern Europe and Central Asia is being threatened by cuts in global health funding, according to “a report [.pdf] by leading European non-governmental health organizations,” Reuters reports. In the report, “experts called on the European Union to step in to fill the gaps left by global donors to countries within and neighboring its borders,” the news service notes. According to Reuters, “[c]ountries in Eastern Europe and Central Asia have some of the world’s fastest growing HIV epidemics,” and “Europe is also home to the world’s highest documented rates of drug-resistant TB” (Kelland, 9/18).

Number Of Recorded Dengue Cases Up 36% Over Last Year In Costa Rica

“A total of 8,480 people have been affected by dengue fever in Costa Rica” so far this year, representing an increase of 36 percent, or 2,230 more cases than during the same period last year, according to a Ministry of Health report, Xinhua News reports. “Among all the cases so far, only nine people were affected by hemorrhagic dengue fever, which is a more serious and sometimes mortal type of dengue, the report added,” the news service writes (9/17). Health authorities are urging people to eliminate possible sources of reproduction for mosquitoes, including disposing of old tires, according to a health ministry press release (9/11).

Mobile Phone Text Messaging Service Allows Health Workers To Track Malaria Cases In Cambodia

A new pilot project in Cambodia is allowing more than 3,000 volunteer health workers to use a special mobile phone text messaging service to report new cases of malaria, in addition to providing no-cost testing and treatment “in remote parts of the impoverished nation, where access to health services can be difficult,” Agence France-Presse reports. When a person tests positive for malaria, health workers begin them on treatment immediately and send a text message with the patient’s age, gender, type of malaria, and location “to the district health center, provincial health officials and a national malaria database in the capital Phnom Penh — a process that used to take a month,” AFP notes. “The information is also fed into Google Earth to create a map of reported cases and of potential hotspots of [malaria drug] resistance,” a problem in western Cambodia, according to the news service. “Together, the data helps officials track each case and make sure the right treatment is available or that more medication is supplied when stocks are running low,” AFP writes, adding, “Some 230 volunteers have used the mobile phone service so far and there are plans to eventually include all volunteers in the project,” which is being implemented by the Malaria Consortium (Se, 9/17).

Speakers At Panel Discussion Explore Policy Implications Of Findings On HIV Transmission Among MSM

The Center for Strategic and International Studies (CSIS) on Thursday hosted a panel discussion focusing on the policy implications of findings published by the Lancet in a special series on HIV/AIDS and men who have sex with men (MSM), the Center for Global Health Policy’s “Science Speaks” blog reports (Barton, 9/7). Chris Beyrer, a professor of international health at the Johns Hopkins Bloomberg School of Public Health and a contributor to the Lancet series, explained two factors are affecting the expansion of the HIV epidemic among MSM worldwide, according to Inter Press Service. First, HIV “is far more efficiently transmitted through the gut, hence leading to a far higher transmission probability in anal sex, for either a man or a woman — around 18 times more likely than through vaginal transmission,” the news service writes. Second, “because gay men can switch sexual roles in a way that is impossible among heterosexual couples — acting as both the acquisition and transmission partner — the efficiency of transmission among MSM networks appears to be far higher than previously understood,” IPS adds, noting, “These two factors, the new research suggests, account for a full 98 percent of the difference between HIV epidemics among MSM and heterosexual populations.”

History Of TB Policy Shows Need For Care, Investment Equity In Developed, Developing Countries

In a 200th anniversary article for the New England Journal of Medicine, Salmaan Keshavjee of the Department of Global Health and Social Medicine at Harvard Medical School and Paul Farmer of Partners in Health “seek to elucidate the reasons for the anemic response to drug-resistant tuberculosis [TB] by examining the recent history of tuberculosis policy,” they write. The authors outline the history of TB drug development and how the disease became resistant to myriad drugs, and write that by the 1970s, “[t]uberculosis, whether caused by drug-susceptible or drug-resistant strains, rarely made even medical headlines, in part because its importance as a cause of death continued to decline in areas in which headlines are written. They continue, “In the United States, federal funding for tuberculosis research was cut; consequently, drug discovery, development of diagnostics, and vaccine research ground almost to a halt.”

Nearly One-Third Of Under-Five Children Malnourished In Southern Afghanistan, Survey Shows

Approximately one-third of children under the age of five in southern Afghanistan, about one million, have acute malnutrition, “with a level of deprivation similar to that found in famine zones, a government survey has found, despite the hundreds of millions of dollars in foreign aid that has been poured into the region,” the Guardian reports. The U.N.-supported “Afghanistan Multiple Indicator Cluster Survey (MICS) found 29.5 percent of children are suffering from acute malnutrition there,” the newspaper states, noting that a level of more than 30 percent is one indicator of famine, as are death rates and families’ access to food.
