Future hotspots for diseases
Sanjay | 21 Feb 2008
A team of British and US researchers, by using the advanced computer models to design a global map of emerging disease hotspots, have pointed out that India, China, and sub-Saharan Africa are the regions where incidences of the emerging lethal diseases like HIV/AIDS and SARS have increased the most, while Europe and North and South America are the places with the least rise in such cases According to the researchers, about 20 per cent of known emergences of diseases are multi-drug-resistant strains of previously known pathogens like tuberculosis. They say that richer countries' by increasing trust on advanced antibiotics has helped breed such life-threatening strains.
They studied 355 disease outbreaks from 1940 onward and reasoned out that diseases springing up in animals were most creditworthy for the emergence of new infections.The group's analyses also revealed that more diseases emerged in the 1980s than any other decade probably likely due to the HIV/AIDS pandemic, which lead to other new diseases in patients with weak immune-system. In the 1990s, as per their report, insect-transmitted diseases saw a peak, perhaps in reaction to speedy climate changes that commenced taking hold then. Study warns that a host of deadly diseases like HIV, Severe Acute Respiratory Syndrome (SARS), West Nile virus and Ebola are flexing their muscles and they can be a cost of development.
