Argentines who returned from Cancun with #covid19 could be false negatives, official says

Marisol Vanegas, Secretary of Tourism of the Mexican state of Quintana Roo, tells CNN that the group of 44 Argentines who were on vacation in Cancun and returned to Buenos Aires with covid-19 were tested for PCR three days before their trip. According to the official, the results of these tests were negative, so there is a possibility that they were false negatives.
