My family came down with the flu right before I was scheduled to return from a business trip and turn around two days later to spend two weeks out of the country. We took as many precautions as possible to avoid spreading it to me (frequent hand washing, not sharing food, all of that) but I also got a preventative Tamiflu prescription. It didn't seem to be in short supply or hard to get -- I literally just described the situation over my healthcare provider's chat app and they sent a prescription to the pharmacy for me to pick up on my way home from the airport. Cost me $10. Whether the stuff works or not is a different question. I read some of the research and meta-analyses and meta-meta-analyses and it didn't seem cut and dry. I can say I didn't get the flu, but there are many other times I didn't get the flu without taking anything.
