Washington (dpa) - In the face of dramatically increasing corona cases, US President Donald Trump has encouraged Americans to wear protective masks.

"We all ask that you wear a mask if you are unable to keep your distance," Trump said at a press conference at the White House. "Whether you like the masks or not, they have an effect, they will have an effect and we need everything we can get."

Trump said again that he had no problem with masks and pulled out a mouth-and-nose protector with the president's logo. "I have the mask here," he said, adding that he wore it when it was appropriate.

There is no nationwide mask requirement in the United States. In view of the dramatically increasing number of infections, however, numerous state governors recently ordered that mouth and nose protection must be worn in public.

Trump presented guidelines from the CDC health authority in April that recommend wearing a protective mask. He immediately made it clear that he would not wear a mask himself. Because he appears without a mask in the vast majority of public appearances, critics accuse him of being a bad example in the pandemic. Trump then wore mouth-to-nose protection during a visit to the hospital last Saturday.

In the United States, authorities have reported between 60,000 and 77,000 new infections and hundreds of deaths in the past two weeks. The states of Florida, Georgia, Texas, Arizona and California are particularly affected. Trump described the recent surge as "worrying." According to experts, the pandemic in the affected areas is now completely out of control. Other states have also been reporting an increase in new infections for days.
