Lockdown can't be extended again and again for an infinite period. In my country (India), a large part of the population are daily wagers and they'll starve to death of the lockdown is not lifted soon. The government may be able to feed them for 2-3 months, but not more (especially as the tax revenue has hit rock bottom). My guess is that the lockdown will be lifted on May 3rd (at least partially), irrespective of whether the situation comes under control or not.
So within 2-3 months, we may witness a limited resumption of the sports activities as well. It will become the new normal, as we can't shut down the economy indefinitely.
Yes, the economic condition in those areas may become worse with the passage of time if the lockdown sustains but you cannot lift the lockdown due to this and say you have no option. Because if the lockdown is lifted and suddenly there are a lot of patients detected of covid19, this could be a worse situation for any country.
As per IMF report the biggest recession is on the way. Third world countries are the one that will be most affected by this lockdown. The situation is so bad that if y ou remove the lockdown medical infrastructure in these countries will collapse and if you continue the lockdown economic condition will get worsen.
India's economy was already struggling before this pandemic and now it will take a deep nose dive after the situation comes under control. Already salaries have been cut and many will lose their jobs now.
