Additionally, a large number of suspect Zika cases from the territories have been tested using molecular testing and none have been positive. The full range of functional disabilities caused by congenital Zika virus infection is not yet known. Sexually transmitted cases are not reported for US territories because with local transmission of Zika virus it is not possible to determine whether infection occurred due to mosquito-borne or sexual transmission. Serologic testing can detect Zika virus-specific IgM antibodies in serum that typically develop toward the end of the first week of illness and may remain detectable for months to years following infection, making the determination of the timing of infection difficult. Caribbean (Zika News). As of early 2020, dengue virus outbreaks were occurring in many areas of the world, whereas low to no Zika virus transmission was being reported globally.

U.S. Department of Health & Human Services. Zika virus disease is a mosquito-borne disease caused by Zika virus. None of these probable cases have tested positive using molecular testing, which detects the presence of the virus in the body and is the best indicator of a recent infection. To date, outbreaks of ZIKV have occurred in Africa, Southeast Asia, the Pacific islands, the Americas, and the Caribbean. Intrauterine, perinatal, sexual, laboratory, and possible transfusion-associated transmission have been reported. In 2007, the first documented Zika virus disease outbreak was reported in the Federated States of Micronesia. ‡Presumptive viremic blood donors are people who reported no symptoms at the time of donating blood, but whose blood tested positive when screened for the presence of Zika virus RNA by the blood collection agency. McArthur MA. Zika virus was identified for the first time in the Western hemisphere in 2015, with large outbreaks in Brazil. Sep. 28, 2020 — Researchers shed new light on how Zika virus hijacks our own cellular machinery to break down an essential protein for neurological development, getting it to 'eat itself'. Cases are reported to CDC by state, territorial, and local health departments using standard case definitions. However, because Zika virus RNA may be detectable for only a relatively short time, a negative NAAT does not exclude recent Zika virus infection. Zika virus, which is spread by mosquitoes, is not harmful to most people. **Includes reported confirmed and probable Zika virus disease cases. Short-term follow-up studies of young children with postnatal Zika virus infections have not identified neurodevelopmental problems; longer-term studies are needed, especially among infants infected during the neonatal period.

The virus then spread throughout much of the Americas, with 48 countries and territories reporting local transmission. Since antibodies against Zika can persist for years after infection, serology cannot distinguish between a recent or past infection. Presumed locally acquired cases of Zika in the U.S. territories were diagnosed using serologic testing, which detects antibodies against Zika. No vaccine or preventive drug is available.

Plaque reduction neutralization testing (PRNT) can be used to discriminate between cross-reacting antibodies in primary flavivirus infections, although neutralizing antibodies might still yield cross-reactive results in people previously infected with or vaccinated against a related flavivirus (secondary flavivirus infection). However, if a pregnant woman is bitten by a mosquito that is carrying Zika, the baby can be born with birth defects, including microcephaly (an abnormally small head). The Zika virus is primarily transmitted by the bite of an infected mosquito from the Aedes genus. Prevent mosquito bites when traveling:.
