Your friend must feel like crap for infecting you. Hopefully, he didn't infect anyone else, especially someone that's immuno-compromise or elderly (over 65) or can not afford to miss any more time off from work (no more sick pay).
With that said, the weather is warm...the car that you and your friend were in together...were the windows rolled down for air circulation ???
By the way,
Natural Immunity does not last +2 years.
- Most likely this was the first time you were exposed to one of the new Covid sub-variants that attacks the immune system differently than the Covid you were infected with back in 2020.
The good thing, most of these sub-variants that have been popping up in 2022 have mainly resulted in
mild illnesses. That's good because it allows for those like you that are not vaccinated to get infected and to re-establish your Natural Immunity for at least another 6 months
or until the next sub-variant shows up.
- Good luck with your health and please stay away from friends / relatives that are immuno-compromise or the elderly.
Last of all, I recently gave my son and two friends of his a ride to their soccer practice. My son and I are fully vaccinated but I discover later (after the ride)...one of his friend's was not vaccinated and infected with Covid...no symptoms.
My son and I tested negative (three negative tests in 2 weeks after the notification of his friends Covid infection) but his friend infected an immuno-compromise (not vaccinated) parent...which result in her being hospitalized for 5 days. Scared the hell out of the dad that had to miss 5 days of work to quarantine because of the exposure.
Their family (the infection) recently returned back from a vacation in Cuba to kick off their summer vacation. Apparently, there was a Covid outbreak at the hotel they stayed at.
Covid like all prior Pandemics...loves people that travel from one country to the another country.
