The Ministry of Health put forth a deadline yesterday that includes a map showing in which cantons there are covid-19 patients. Keep in mind that this map does not show the exact location, just the cantons.
The majority of cases of covid-19 in Costa Rica are in the metropolitan area, including San Jose, Heredia, Alajuela and Cartago. They continue to Grecia and Atenas as well. Some of the cantons with infected people are Santa Barbara, San Pedro de Poas, Barva, San Pablo, Santo Domingo, San Juan District of Tibas, Curridabat, Desamparados, Mata de Platano, Santa Ana, and Escazu.
A few cases outside this zone are found in Limon, San Isidro De El General, Nicoya, and Santa Cruz.
