“Diseases caused by the other flaviviruses have been intensively studied for many years without microcephaly turning up as a complication,” he wrote. “It hasn’t been clearly evident in Zika virus outbreaks elsewhere in the world. But flaviviruses mutate in real time. The classic example is West Nile virus. Isolated at the Rockefeller Yellow Fever labs in Uganda in 1937, like Zika it remained quiet for years. Then in the mid-1990s it got nastier, causing severe brain disease with epidemics in North Africa and Southern Europe. It took off in New York in 1999, and spread rapidly across the continent.” Continue reading →
