People may have antibodies for at least four months after they get COVID-19, a study published on 1 August in the New England Journal of Medicine suggests.

The study pulled from a massive dataset from Iceland, looking for the presence of antibodies in 30,576 blood samples.

The samples came from three groups of people: those with confirmed COVID-19 cases, those who had been exposed to the virus but weren't necessarily infected, and those who had no known exposure.

RESULTS:

Antiviral antibody titers assayed by two pan-Ig assays increased during 2 months after diagnosis by qPCR and remained on a plateau for the remainder of the study.

Of quarantined persons, 2.3% were seropositive; of those with unknown exposure, 0.3% were positive.

Researchers estimated that 0.9% of Icelanders were infected with SARS-CoV-2 and that the infection was fatal in 0.3%.

Also, estimated that 56% of all SARS-CoV-2 infections in Iceland had been diagnosed with qPCR, 14% had occurred in quarantined persons who had not been tested with qPCR (or who had not received a positive result, if tested), and 30% had occurred in persons outside quarantine and not tested with qPCR.

CONCLUSIONS:

The results indicate that antiviral antibodies against SARS-CoV-2 did not decline within 4 months after diagnosis. The estimated risk of death from infection was 0.3% and that 44% of persons infected with SARS-CoV-2 in Iceland were not diagnosed by qPCR.
