2. Zika is Not Contagious via Casual Contact
While the common flu and H1N1 virus (the latter which an Olympic athlete, Sudha Singh of India, is recovering from after returning from Rio) are both considered contagious through non-intimate human contact, Zika is mostly still just spread through infected mosquitoes, according to IFLScience.
However, there have been some cases of Zika being spread through intercourse (from male to female, male to male or female to male), adds the source. While it can be spread through intimate contact, it’s not being considered an STD, according to a doctor cited in the article. While the virus has been detected in saliva, experts are saying kissing does not pass it along.
