The onslaught of Zika stories in the media continues while the science lags. Searching “Zika” on Google News produces 86,500,000 results.

It isn’t the largest mosquito, but today it caused the World Health Organization to declare an international public health emergency. Aedes aegypti, the Yellow Fever mosquito, carries and transmits the Zika virus and Zika viral illnesses are being blamed for large numbers of microcephaly cases in Brazil.

The information in this article is what is known by medical and public health authorities at this time. Links are included to provide sourcing and further information.

The EPA has mandated that such reservoirs be covered. Sunlight has been causing a reaction turning bromide in the water into bromate. a suspected cancer causing chemical. And, in the wake of multiple years of severe drought, open air reservoirs lose millions of gallons of water to evaporation.
