In addition, two travelers tested positive during a cruise in Polynesia and were isolated on board. In the profile of patients infected by the virus, there is a predominance of cases among those over 60 years of age, but this is explained “partly due to the recent diagnosis of several cases in older people on cruise ships”.

Five are from the BA.2 sublines that have already circulated actively in Polynesia, but one strain has the so-called “L452R” mutation, which is found in the BA.4 and BA.5 sublines, in a Polynesian resident patient. returning from a trip to the United States. Still, no patient has been hospitalized for Covid for two weeks. Only seven patients are currently treated for the aftermath of a long Covid in the Ora-Ora center.
