We've been trying to follow (and make sense of) news coverage about the Zika Virus (ZKA). There are apparently-conflicting viewpoints among published accounts and between subject-matter experts and, naturally, who better to sort it all out for the reader than… me?

Everybody Seems to be First

General-audience accounts of a Dallas case of Zika may need to be parsed carefully to understand the underlying story. The first sexually-transmitted Zika case in the US, during the recent Western hemisphere outbreak in the US was reported in Dallas County (Texas), according to Dallas County Health and Human Services.
[2] [3]

The patient, who is not identified, became infected after having sexual contact with someone who was ill and had returned from a country where the Zika virus is present, officials said.

Before that was another first. In 2008, two health workers returned to the US from Africa. [4] One transmitted the disease to his wife through sexual intercourse. This w a goodas documented in a study, which was autobiographical fo the first author. [5]

In another Zica first, the first case of brain damage believed linked to the Zika virus within the United States was reported on Friday in Hawaii.

The mother had lived in Brazil last year and was likely infected by a mosquito then and there, health officials said.

The virus was first isolated in April 1947 from the serum of a pyrexal rhesus monkey caged in the canopy of Zika Forest. [6]

A second isolation was made from a lot of A. africanus in January, 1948, from the same forest. Zika virus was named after the locality from where the isolations were made.
