At this stage, it's evident that the primary mode of SARS-Cov-2 transmission is through aerosols, not droplets nor fomites. The level of air pollution affects the duration of suspension of bioaerosols as well as the performance of the innate immune system. Low humidity is also linked to higher transmission.

The level of air pollution is relatively the same now as it was last year for the first wave though. The air pollution isn't helping things but if it were that one thing, why would the second wave look any different from the first?

  > The level of air pollution is relatively the same now as it was last year for the first wave though. No, they are not. See table 1 of https://www.orfonline.org/research/air-pollution-delhi-filling-policy-gaps/ https://www.orfonline.org/research/air-pollution-delhi-filli... - it hit a low point in October, but was much better during lockdown and relatively better post-lockdown although trending towards worse levels.
