Now that public transport systems like metros, buses are open for use, be very careful about touching high-contact surfaces while you travel. The same goes for flights. Even though social distancing norms are followed to the fullest, the poles and windows are made out of steel, glass and similar material, which can be a good place for viruses to breed in low-moderate temperature settings.
