He also served all the meals to the customers on the planes with Coronavirus infected hands. That means all the meals he served were contaminated with Coronavirus.
It is highly possible that those people to Israel and to Los Angeles got infected with Coronavirus and spread their virus to hundreds (if not thousands) of people in Israel and Los Angeles.
As you know, both Israel and Los Angeles are really populated areas. This might bring Coronavirus Pandemic in both Israel an Los Angeles.
