The Bonn virologist Hendrik Streeck is concerned about the live television broadcasts of the soccer World Cup from Qatar next winter.
"As a result, we may also create larger outbreaks again, or there may also be a superspreading event, and you have to prepare for that," Streeck told the RTL television station's "Nachtjournal".
The reason for this is that the public viewing will take place indoors due to the unusual time of year and not outdoors as is usually the case.
Wearing protective masks could then be of help again.
"We know that the mask works and that the mask provides protection," said the head of the Institute of Virology at the University of Bonn.
But above all, the risk groups in old people's and nursing homes must be better protected.
This includes good hygiene concepts, but also a fourth vaccination for risk groups.
Younger people don't need this at the moment, a triple vaccination is enough for them.
The corona numbers in Germany are currently increasing rapidly again.
A new Omikron variant is responsible for this, among other things.
"BA.5 has increased immune escape," Streeck said.
“People who have been vaccinated can become infected again because the immune system can no longer recognize the variant quite as well.
In addition, it is also somewhat more contagious.” That is why you have to prepare very well for the upcoming autumn and winter.
