If you want to minimize the chance of getting COVID/passing COVID onto loved ones, you should look at the process in countries with the lowest rates of infection, like China. It might be overkill, but better safe than sorry.
1. Get both doses of the vaccine.
2. Two week pre-flight self-quarantine.
3. Negative NAT test within three days of boarding the plane.
4. Mask up the entire duration of the flight.
5. NAT test upon landing.
6. Two week post-flight quarantine.
7. NAT test at approx. 1 week into quarantine and at the end of quarantine.
And obviously, avoid crowded places and wear a mask whenever you step outside the door. It’s a lot, but we basically have zero cases in Shanghai, a crowded city of 30 million people, so I guess the government here is doing something right.
When you’re ready to fly back to Italy and want to make sure you don’t infect your kids/husband because your anti-vax stepmom may have passed it to you, then do the above steps again. If your dad’s place is too small you can do the NYC quarantine in an Air BnB.
