Zika Virus:


Alarmed by cases of Zika virus in neighbouring Kerala, Karnataka has issued guidelines to prevent the spread of the disease in the state.


How does the Zika virus spread?

  • The Zika virus is predominantly transmitted by infected mosquitoes from the Aedes genus, mainly Aedes aegypti. The Aedes mosquitoes also spread dengue, chikungunya and yellow fever. They usually bite during the daytime, mostly during the early morning or later afternoon.
  • Apart from the mosquitoes, an infected person can also spread the virus. This virus can be transmitted from a pregnant woman to the fetus, through sexual contact, transfusion of blood and blood products, and organ transplantation.

The virus 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.


What are the symptoms of the Zika virus?

While the symptoms of the Zika virus are mild, in case it gets worse, immediate medical attention is advised. Generally, the symptoms include fever, rash, conjunctivitis, muscle and joint pain, malaise, or headache. It lasts for about two to seven days. Most infected people do not develop any symptoms.


What is the treatment?

According to the World Health Organisation (WHO), the Zika virus has no treatment or vaccine. WHO advises the consumption of a lot of fluids along with pain and fever medicines for a speedy recovery.
