In the past few years, India has been plagued with diseases that involve unique and less known viruses from around the world. We’ve always been wary of mosquitoes that are part and parcel of our sub-tropical climate. They are the carriers of most viruses and have been wreaking havoc since decades, mostly without being detected. Dengue, kala-azar, yellow fever, Malaria and the likes have taken away several lives when treatment was sparse in the early 20th century. Growing up in West Bengal, we have been using a mosquito net since forever and while it is irksome to manage, it has probably prevented quite a few diseases. But the usage is getting rare these days as it is an inconvenient and confined measure to prevent the mosquitoes and more families are opting for other convenient methods.
Zika virus : The rise and spread
I wasn’t aware of the Zika virus until a few years ago but now I know that it was discovered long ago in Africa, though it also has an Asian strain. It was limited to Africa until 2007 and began spreading in Asia post that. Zika virus is transmitted through the mosquito species Aedes aegypti that also carries deadly viruses of Dengue, Malaria and Chikun guniya. The mosquitoes bite an infected human and then a non-infected one to transmit the virus. While it has always been prevalent in Africa, only a few cases have been recorded in India yet. But don’t let that fact deter you from gathering prevention from Zika virus as there is no vaccine invented yet.
