The World Health Organisation (WHO) says there is no
evidence that those who recover from COVID-19 cannot get reinfected.
In a brief published on Friday, the global body said some
governments have suggested that the detection of antibodies could serve as the
basis for an “immunity passport” or “risk-free certificate” that would enable
individuals to travel or to return to work with the thought that they are
protected against reinfection.
But WHO said they continue to review the evidence on
antibody responses to the infection.
“Most of these studies show that people who have recovered
from infection have antibodies to the virus. However, some of these people have
very low levels of neutralizing antibodies in their blood, suggesting that
cellular immunity may also be critical for recovery,” the brief read.
“As of 24 April 2020, no study has evaluated whether the
presence of antibodies to SARS-CoV-2 confers immunity to subsequent infection
by this virus in humans.
“Laboratory tests that detect antibodies to SARS-CoV-2 in
people, including rapid immunodiagnostic tests, need further validation to
determine their accuracy and reliability. Inaccurate immunodiagnostic tests may
falsely categorize people in two ways.
“The first is that they may falsely label people who have
been infected as negative, and the second is that people who have not been
infected are falsely labelled as positive. Both errors have serious
consequences and will affect control efforts.
“These tests also need to accurately distinguish between
past infections from SARS-CoV-2 and those caused by the known set of six human
coronaviruses. Four of these viruses cause the common cold and circulate
widely. The remaining two are the viruses that cause Middle East Respiratory
Syndrome and Severe Acute Respiratory Syndrome. People infected by any one of
these viruses may produce antibodies that cross-react with antibodies produced
in response to infection with SARS-CoV-2.”
WHO said many countries are now testing for COVID-19
antibodies at the population level or in specific groups, such as health
workers, close contacts of known cases, or within households.
The organisation added that it supports studies that will
provide data on the percentage of people with detectable COVID-19 antibodies,
but most are not designed to determine whether those people are immune to
secondary infections.
Earlier in April, the Korea Centers for Disease Control and
Prevention said a total of 91 people tested positive for the new coronavirus
after they were released from quarantine in South Korea.
