I flew from India to the US in early February (2nd week).
Indian airports were doing thermal checks on passengers (using tech that had been installed during the Zika virus scare a few years back, I believe). The newspapers also had info about how anyone found with elevated temperatures were being asked to self quarantine, and the police was also following up.
The US had, absolutely nothing. Nada. Before the flight I was afraid that entering the US would be difficult, but it was clear (and it remained this way for over a month), that if anything, entering India, if not difficult, would actually involve checks, something that was non existent in US ports.
Further, and I don’t know if this is mentioned, the flight into India involved the cabin crew spraying some sort of pest control spray in the cabins before we landed. They mentioned it was due to regulations. Considering SARS-COV-2 has been found to have been easily killed (within minutes) of exposure to common disinfectants, could this spray have greatly minimized the virus entering the country, on baggage’s and clothing, etc?
