Zika Virus common or rare
Zika virus (sometimes termed Zika fever) is a Flavivirus that is related to dengue, West Nile, yellow fever, and Japanese encephalitis viruses (Flaviviridae); the viruses are transmitted to humans by mosquito bites and produce a disease that lasts a few days to a week. Common symptoms include fever, rash, joint pain, and conjunctivitis (redness of the eyes). In Brazil, the viral infection has been linked to birth defects (mainly small head and small brain size, termed microcephaly) in babies (newborns) whose mothers became infected with the Zika virus during their pregnancy. The CDC reported that researchers now conclude from new data published in the New England Journal of Medicine in April 2016, that the Zika virus is responsible for (causes) microcephaly and other serious brain defects. According to CDC Director Dr. Tom Frieden and other experts, these findings should serve as a warning to the U.S. to take Zika virus infections very seriously.Initially, in most outbreaks, the virus requires a mosquito vector to pass the virus to humans. Theoretically, donated blood and organ transplantation can allow rare person-to-person transmission. However, once a person gets a Zika infection, the virus can be contagious from that person to another person -- under certain conditions, by sexual contact. Transmission of Zika viruses to sexual contacts occurs more frequently than previously suspected; research is ongoing.
