Travel to Z

First if you are not vaxxed and boosted, it’s probably not a good idea to travel anywhere now. Ideally the vax and booster should be either Pfizer or Moderna. Other vaccines boosted with either Pfizer or Moderna would come close to that level of protection. Any other combination is not likely to provide much protection. While it is likely the Omicron variant is less severe, it is too early to be confident in this. Even though it may be less severe, since vastly increased numbers are contracting it, the net effect in terms of absolute numbers still seem to be straining many hospitals. Thousands of flights have been cancelled worldwide because aircrews are testing positive leading to a shortage of pilots and flight attendants.
Numbers of positive tests in Zihuatanejo are probably not an accurate measure as they only test symptomatic people. In the states around 40% of positive tests are in asymptomatic patients. Although people say that masking is well followed in Zihuatanejo, our personal experience right after Thanksgiving downtown showed at most 25% of people masked. Subsequent videos showed similar numbers. Although people were outside, given the level contagion of this variant, unmasked groups, even outside, increases risk.
Should you chose to travel, I would do so only with N-95 or KN-95 masks. Well fitting surgical masks are around 65% effective. Most cloth masks are Covid theater. Indoor restaurants would not be a good idea, but luckily that’s easy enough to avoid. Walking everywhere would be safest. Taxis, with masks and open windows, would be relatively safe. I would avoid the combis with multiple people and poor air flow.
Luckily we don’t travel until mid February and are hopeful that things will be more clear by then.
