More on the Belgian lady infected twice
"The Belgian case was a woman who had contracted Covid-19 for the first time in March and then a second time in June.
Belgian virologist Marc Van Ranst told Belgian broadcaster VRT that the woman, whose symptoms were relatively mild, may not have created enough antibodies to prevent a reinfection, although they might have helped limit the sickness.
“I think that in the coming days that we will see other similar stories ... These could be exceptions, but do exist and it’s not just one,” Mr Van Ranst said. “It’s not good news.”
In the Hong Kong case, gene sequencing was carried out to prove that the man had been infected with two different strains of Sars-CoV-2.
