sama jugak bukankah terlalu awal utk pointfinger kat zika virus sedangkan yg positif dlm darah ada virus tu hanya beberapa org baby dari ribu2 yg affected tu?dan taburan zika virus ni luas - India, SEA, Africa
What is the Zika virus?
A tropical infection new to the Western Hemisphere.
The Zika virus is a mosquito-transmitted infection related to dengue, yellow fever and West Nile virus. Although it was discovered in the Zika forest in Uganda in 1947 and is common in Africa and Asia, it did not begin spreading widely in the Western Hemisphere until last May, when an outbreak occurred in Brazil. Until now, almost no one on this side of the world had been infected. Few of us have immune defenses against the virus, so it is spreading rapidly. Millions of people in tropical regions of the Americas may now have been infected. Yet for most, the infection causes no symptoms and leads to no lasting harm. Scientific concern is focused on women who become infected while pregnant and those who develop a temporary form of paralysis after exposure to the Zika virus.
How might Zika cause brain damage in infants?
Experts aren’t certain how it happens, or even whether the virus is to blame.
The possibility that the Zika virus causes microcephaly – unusually small heads and damaged brains – emerged only in October, when doctors in northern Brazil noticed a surge in babies with the condition. It may be that other factors, such as simultaneous infection with other viruses, are contributing to the rise; investigators may even find that Zika virus is not the main cause, although right now circumstantial evidence suggests that it is.
It is not known how common microcephaly has become in Brazil’s outbreak. About three million babies are born in Brazil each year. Normally, about 150 cases of microcephaly are reported, and Brazil says it is investigating nearly 4,000 cases. Yet reported cases usually increase when people are alerted to a potential health crisis.
