This virus use to spread through respiratory droplets produced when an infected person coughs, sneezes, or talks, and can also be spread via contaminated (dirty/polluted) surfaces. Reasons like post-monsoon waterlogging, changing temperatures, and increased outdoor activities have subsidized to the spike in cases.
