Considering the ease with which Covid-19 moves from person to person (infects others), I'm not sure I would want to visit a family member who has sheltered in and is safe. Both my parents have died 10 or more years ago; so, it's not really an issue for me, but I have a new grand-nephew who was born 2 weeks ago. Even though I've sheltered in for over 2 weeks and I have no symptoms, and I haven't been in the company of anyone (in the last 2 weeks) who has been found to be infected (that I know of), I would not under any circumstances go to meet my grand-nephew at this time.
Think of all the places I would have to go into/through and people I would have to encounter that I would just have to trust were not infected with the virus--cab to the airport, airport terminal its self, the airplane, the baggage claim, cab driver, baggage check personnel, ticket counter agent (no longer a company employee BTW), the gate agents, the flight attendants, the other passengers and on and on). Having the proud grandfather, aka my younger brother, send me daily photographs is the preferred solution.
Good call Jim. Don't take the chance on a newborn who doesn't even have a built up immune system as of yet. I know how bad you would love to go see him, but I too would choose the pics and maybe even video face to face for a bit. Great choice.
