The Chilean Minister of Health has announced that these cards will be delivered to anti-virus antibody detectors, despite the difficulties scientists face in making reliable tests, according to The Guardian.

The cardholder has promised that "no one will be infected with the disease with a very high probability."

Chile considers that patients are no longer pollutants 14 days after the most severe symptoms or, in the case of more severe cases, after hospital discharge. For people with a weakened immune system, they will be considered non-contaminating 28 days after the onset of symptoms.

This measure is creating uncertainty at the international level. For example, at the daily press conference of the World Health Organization a journalist asked them about the issue and the organization did not want to position itself. He has recommended to countries that they be extremely prudent, insisting that "the effectiveness of studies must be continually questioned".

For example, the Center for Disease Control and Prevention in South Korea reported that 141 patients tested positive for the second time. According to the Italian National Institute of Health, only 10% of patients have developed antibodies in recent hours.

According to The Guardian, this strategy to raise quarantines is based on forwarding people to work, and some believe that with Immunity Cards you can create a black market.

According to official statistics, Chile has recorded 9,252 cases of Covid-19, of which more than half are in quarantine in Santiago de Compostela. At least 116 deaths have been linked to the pandemic.
