This is evident from the results of the source and contact investigation of the GGD Friesland. The investigation is still ongoing, but the GGD suspects that most of those involved have now been identified. According to the local health authority, everyone who was infected has been quarantined. Nobody had to go to the hospital.
More and more young people are becoming infected with the corona virus, but until now this has mainly happened indoors. The Frisian cluster shows that the virus can be very contagious in the open air.
Scientists in Hong Kong previously painted a completely different picture: among more than 7,000 infections, they found only one case of someone contracting the corona virus outside. By far the most contagious.
