Zika virus Disease

Zika virus Disease is mosquito-borne virus transmitted by Aedes aegypti mosquitoes which also transmit three other vector-borne diseases Chikungunya, dengue and yellow fever. The virus belongs to family Flaviviridae and Genus Flavivirus. It was first identified in 1947 in Zika Forest, Uganda from where it derives its name. Now it is emerging disease currently being reported by 86 countries worldwide.

Transmission: It is transmitted primarily by infected Aedes aegypti mosquitoes, which also transmits dengue. It can also spread through blood transfusion and sexual contact.

Symptoms: They are similar to other viral infections such as dengue, and include fever, skin rashes, conjunctivitis, muscle and joint pain, malaise, and headache.

Threats: Pregnant women infected with Zika virus may give birth to babies with severe brain damage or serious birth defects i.e. neurological disorders and foetal deformation known as Microcephaly in which infants are born with abnormally smaller heads. Besides there is also possible link between virus and Guillain-Barré syndrome (a condition in which the body’s immune system attacks part of the nervous system) is also suspected.

Treatment and Prevention: There is no specific treatment or vaccine currently available to treat Zika. The best form of prevention is protection against mosquito bites and clearing stagnant water where mosquitoes breed.

Previous Outbreaks in India: First outbreak of Zika Virus was reported in Ahmedabad, Gujarat in January/February 2017 and second outbreak in July 2017 from Krishnagiri District in Tamilnadu. Both these outbreaks were successfully contained through intensive surveillance and vector management.
