Ever since a Hong Kong research team was the first to report recontamination on August 24, cases have been reported by scientists worldwide on an almost daily basis. Also in our country there are at least three reinfections. This happened with certainty with a thirty-year-old general practitioner from Antwerp, a 25-year-old woman and a 51-year-old woman.
The threshold to be able to record a recontamination is very high. Since the virus can still circulate in the body for a long time, it is not enough to test positive twice. Genome analysis is needed to be sure. In addition, the virus must be mutated enough to ensure that the mutation did not occur in the host or woman. In addition, scientists would also be less inclined to publish an established recontamination, now that they are no longer the first. According to De Standaard, it may therefore be the tip of the iceberg.
It is also certainly not the case that catching the disease a second time is always milder. The immune response can sometimes not last long after an infection. Nevertheless, several studies have already shown that an infection can offer protection. In fact, there are still insufficient reports to know whether a second infection is usually more serious or milder, the head of the virology department at the Institute of Tropical Medicine (ITM) Kevin Ariën told De Standaard.
