There were already five known cases of this thing in San Diego. The best precaution is to stay home and avoid public areas. Stock up on frozen food before s**t hits the fan. Mexico City is already up to 1000 incidents. Most San Diego incidents were unrelated and date back to late March – early April. The number of infected people is much higher now. I wouldn’t be surprised if San Diego is into hundreds by June.
The mortality rate in Mexico was so far ~5% among healthy young people. Fortunately, the virus is known to be susceptible to oseltamivir (Tamiflu) and we can expect the government to help out if there are shortages of the medication. Just to be safe, you might want to get some yourself. It’s prescription-only in the US but freely available in Tijuana. Get some now before border pharmacies jack up prices.
