Zika virus infection may prevent reinfection, study finds
People infected with Zika virus may not be susceptible to Zika virus again, according to the latest research. Other findings show that Zika virus is present in the blood very early during infection and remains in some tissues for a long time but is only briefly present in other tissues. Ref. Source 2l.
Zika infection causes reduced fertility, low testosterone in male mice
Zika targets the male reproductive system, at least in mice, say researchers. Three weeks after Zika infection, male mice had shrunken testicles, low levels of sex hormones and reduced fertility. The results suggest that Zika infection may interfere with men's ability to have children. Ref. Source 7o.
Zika virus can live for hours on hard, non-porous surfaces
The Zika virus is most commonly transmitted in humans as the result of a bite from an infected mosquito or from an infected human to another human. What is not well known is that the virus also can be transmitted via the environment if an individual is pricked with an infected needle or has an open cut and comes in contact with the live virus. While there are no known cases to date of the general public being infected with the Zika virus through the environment, there has been at least one documented case of laboratory acquired Zika virus infection. Ref. Source 1o.
For the first time, researchers identify key proteins that may make Zika so deadly
Now, a new study has for the first time identified seven key proteins in the virus that may be the culprits behind this damage. The study is the first comprehensive description of the Zika virus genome. Ref. Source 8n.
Zika virus persists in the central nervous system and lymph nodes of rhesus monkeys
Zika virus can persist in cerebrospinal fluid (CSF), lymph nodes and colorectal tissue of infected rhesus monkeys for weeks after the virus has been cleared from blood, urine and mucosal secretions, according to a study. Ref. Source 7d.
