If you want to offer some bets according to the covid situation, then you have to be fast because in some months the covid will be over because of the vaccination program 
AFAIK, there some betting events son Futuur's site about Covid-19.... as far as I can remember it is about Covid-19 vacine. If you wawnna bet, just visit their site and you'll immediately findd it. You can find lots on here: https://futuur.com/q/category/2181/covid-19-coronavirus
Example of given market:
How many deaths will be caused by Covid-19 in Brazil by the end of 2021?
Will Covid-19 infection kill more people globally than Influenza in 2021?
i can say, not a very good section to bet on. but that's the reality of life. we cant avoid this crisis. but it is good that vaccine has started to roll-out in all parts of the globe, though some are still waiting their turn. but at least we are already slowly containing this pandemic.
