In April of 2016, reports were streaming in of Zika cases across the Americas. Each report reinforced the conventional wisdom that Zika was primarily a threat to the western hemisphere and that, so far, mainland Africa had been spared its pernicious effects. Then came a report from Guinea-Bissau.
This biomedical smart jacket distinguishes pneumonia’s symptoms – temperature, breathing rate and sound of the lungs – and eliminates most human error, diagnosing pneumonia at a rate three to four times faster than a doctor.
Presently, according to WHO, outbreaks of yellow fever are occurring in more than six of Angola’s 18 provinces. Should yellow fever outbreaks occur elsewhere in Africa, in Latin America, or in Asia, current global supplies of yellow fever vaccine will be inadequate.
“This is a critical step forward in tackling the MDR-TB public health crisis,” said Dr Mario Raviglione, Director of WHO’s Global TB Programme. “The new WHO recommendations offer hope to hundreds of thousands of MDR-TB patients who can now benefit from a test that quickly identifies eligibility for the shorter regimen, and then complete treatment in half the time and at nearly half the cost.”
A vaccine to prevent infection and disease caused by P. vivax is critical to reduce sickness and mortality from vivax malaria, a common cause of malaria among deployed service members. P. vivax malaria is challenging to control because it can be dormant, causing no symptoms, and then become active causing symptomatic malaria weeks to months after initial infection.
A comprehensive review of secondary data sources has confirmed a long-suspected link between female genital schistosomiasis (FGS) and HIV infection for women in southern Africa. Researchers confirmed the link in Mozambique, finding that exposure to schistosomiasis, combined with HIV prevalence, increases the odds of HIV infection by three times. Researchers also conclude that treating young girls for schistosomiasis could avert millions of new cases of HIV infection at far less cost than treating HIV infection once it has occurred.
The Zika virus reached South Africa in February, with one reported case. At the time of this posting, no other confirmed cases have been reported in Southern Africa, and evidence suggests its impact here will be comparatively slight.
The World Health Organization has warned that African governments should be on the alert for the possible spread of the virus. But what is Zika virus? What are the symptoms? Watch the Zika Q&A video published by the WHO and find the answers!
