As refreshing as it may feel, the onset of the rains brings with them a host of diseases and infections that can pose a serious range of health threats for you and your family. The risk of being exposed to multiple viruses, bacteria and other infections is two times higher during the monsoon than in any other season. During this time mosquito borne diseases like malaria, dengue, Chikungunya are at the peak. Whether you are staying at home or traveling, preventing mosquito bites is the best way to reduce the risk of mosquito-borne disease. Mosquitoes can be found in different environments and you may not always notice when you have been bitten.

When a mosquito feeds on blood, it also swallows viruses or parasites living in the blood. These viruses and parasites can be transferred to the next person the mosquito bites through its saliva. Any disease that is spread in this way from mosquito to human is known as a ‘mosquito-borne disease’. These mosquito-borne diseases can cause immense suffering for humans.

We should take as many precautions as possible to protect ourselves and our family from being bitten by mosquitos. Bites can occur at any time between dusk and dawn, but some are more active during the daytime.
