National Institute of Virology based in Pune has warned that there is wide spread of the Zika virus, along with dengue and chikungunya, in several States and Union Territories. The spread has established local transmission.
Based on 1,520 clinical samples collected from 1,475 patients in country the National Institute
of Virology (NIV) has established local transmission of Zika Virus in India.
Zika virus disease is caused by a virus transmitted primarily by Aedes mosquitoes, which bite during the day. Zika can be passed from a pregnant woman to her fetus. Infection during pregnancy can cause certain birth defects. There is no vaccine or medicine for Zika.
Symptoms are generally mild and include fever, rash, conjunctivitis, muscle and joint pain, malaise or headache. Symptoms typically last for 2–7 days. Most people with Zika virus infection do not develop symptoms.
Zika virus infection during pregnancy can cause infants to be born with microcephaly and other congenital malformations, known as congenital Zika syndrome. Infection with Zika virus is also associated with other complications of pregnancy including preterm birth and miscarriage.
An increased risk of neurologic complications is associated with Zika virus infection in adults and children, including Guillain-Barré syndrome, neuropathy and myelitis.
Zika virus is a mosquito-borne flavivirus that was first identified in Uganda in 1947 in monkeys. It was later identified in humans in 1952 in Uganda and the United Republic of Tanzania.
Before 2007, at least 14 human cases of Zika had been documented, although other cases were likely to have occurred and were not reported. Zika outbreaks have probably occurred in many locations. Because the symptoms of Zika are similar to those of many other diseases, many cases may not have been recognized.
How Zika spreads ?
- Mosquito bites
- From a pregnant woman to her fetus
- Sex with an infected person
- Laboratory exposure
What is Guillain- barré syndrome (GBS) ?
GBS is an uncommon sickness of the nervous system in which a person’s own immune system damages the nerve cells, causing muscle weakness, and sometimes, paralysis.
GBS is strongly associated with Zika but only a small proportion of people with recent Zika infection get GBS.
