A visiting biologist at the University of California, San Diego and her colleagues in Africa and Britain have shown that there are close linkages between outbreaks of Ebola hemorrhagic fever in human and wildlife populations, and that climate may influence the spread of the disease.
An increasing number of countries and regions are transitioning from deforestation to afforestation, raising hopes for a turning point for the world as a whole, according to researchers advancing a more sophisticated approach to measuring forest cover. The novel approach looks beyond simply how much of a nation’s area is covered by trees and considers the volume of timber, biomass and captured carbon within the area.
As the prevalence of allergic rhinitis appears to be rising, there are increasing concerns about its impact on health, sleep, work and school performance, as well as unmet patient needs regarding its treatment according to experts presenting new data at the Annual Meeting of the American College of Allergy, Asthma and Immunology (ACAAI).
Diabetes cases are increasing faster in Asia than in developed countries with people developing the metabolic disease at a younger age and suffering more complications, the Lancet said, citing researchers in South Korea.
The key to combating AIDS in Russia may be to treat HIV-infected drug users. A new model estimating the spread of HIV in Russia suggests that treating injection drug users with antiretroviral medication will slow transmission of the virus among the general population.
An estimated 50 million people were affected by zoonotics diseases, including H5N1 (bird flu), SARS and Rabies, between 2000 and 2005 and up to 78,000 died. No effective vaccines exist for the most common diseases. And the Dengue virus, which caused about a third of the deaths is experiencing a global resurgence. Zoonotic diseases can become serious killers if they adapt to human to human transmission — HIV and Measles are two examples.
Researchers who thought they had identified the bacterial perpetrator of the often severe disease caused by community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) had better keep looking: Scientists at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, have exonerated a toxin widely thought to be the guilty party.
A leading population expert will today make a plea for a revitalization of the family planning agenda in the world’s poorest countries, cautioning that soaring population rates are now a bigger threat to achieving the MDGs than HIV/AIDS.
With the help of some high tech equipment, well-defined mouse models and analytical know how, researchers are trying to understand why a flu virus kills some people but not others. Studies to be presented at “Physiological Genomics and Proteomics of Lung Disease” found that a strain of mice more likely to die of influenza infection mounts a dramatically enhanced immune response in the lungs compared to a strain of mice that generally develops milder disease.
Uganda’s success in reducing HIV prevalence and improving reproductive-health status compared with neighbouring countries has been attributed to the selective emphasis on the abstinence and being faithful strands of the ABC strategy in the country’s HIV programmes.
