I don't know whether the fungal epidemic, combined with the COVID-19 pandemic, will depopulate India in some way
For your own good, stop making such statements. India high fertility rate will easily overcome this. In the worst case demographic growth will be slighlty lower. There are a lot of cases and a lot of deaths in the first place because the population is HUGE, and everything is proportional. More than 1 billion inhabitants ! But certainly nothing catastrophic will happen.
India is absolutely not going to be "depopulated" in any way. Not only humans are in general very resilient as a species, but this is even more true in countries that have to deal everyday with a limited healthcare system, mass poverty, etc... Also indian population is very very young if you compare it to Europe. Young people are less affected. Now, obviously, people with obesity, diabete, any kind of serious chronic illness (asthma is common in huge polluted cities such as Mumbai or Dehli) or simply great age should be extremely careful. This is obviously serious and above all people should be careful, wear masks (not easy in hot climate I know, I lived that in Morocco last year, but there's no choice, period) and wash hands often, but you're a long way from the end of the world.
