São Paulo Dengue Forecast
Salvador Dengue Forecast
The number of new cases of Zika in Brazil is dependent on the number of infections in 2015, as infection likely leads to short-term immunity. Beyond Brazil, many other countries in South and Central America are being hit with a wave of Zika infections that may potentially lead to an increase in microcephaly in ~6 months should the linkages be confirmed. Preventative health guidelines from the WHO, PAHO, and national health authorities should be followed.
