Any infection disease will spread in an ill aerated room
Further risk of pneumonia spread is high if any one with respiratory infections sleep along with you..
My opinion is to avoid ac till the epidemic is under control
If your place is too hot you can use intermittently
Next Steps
In few days we will live like our grandfathers lived
They didn't have luxury
still they lived a happy life
Measure the risk vs benefit yourself
Bcoz I can't give reference for your question
It is only based on experience
Others opinion may vary
