Germany may not have enough hospital beds and ventilators to tackle its coronavirus outbreak, the head of the country's disease control agency warned on Friday.

''I am very happy that the ventilation beds and intensive care capacities have been increased," Lothar Wieler, the head of the Robert Koch Institute, told reporters. "Still, I cannot be sure that these capacities are sufficient enough.

"Personally, I have the opinion that they will not be enough and I am happy if I am wrong," Wieler added. "The more ventilators and intensive care beds we have, the more lives we will be able to save and therefore I ask that we continue to ask that we increase the capacities as much as possible.''

Wieler went on to say that he believes ''more people will die of Covid-19 than reported." Germany's mortality has rate increased to 1.2%, and Wieler warned against the assumption that the virus only affects older people -- pointing out that Germany's youngest confirmed death was a 28-year-old woman with a pre-existing condition.

Germany sent 50 ventilators to Spain to help that country battle its coronavirus outbreak, the German health minister said on Friday.

"Especially in times of coronavirus we stick together. We wish the Spanish much strength in these times," Jens Spahn said.

Spain has been battling one of the worst outbreaks of Covid-19 anywhere in the world, passing 10,000 virus-related deaths on Thursday. Only Italy has recorded more fatalities, and only Italy and the United States have had more confirmed cases, according to John Hopkins University.

Meanwhile, a poll has shown that the vast majority of Germans approve of Angela Merkel's response to the outbreak.

About 72% of Germans support the government’s approach, according to the poll by Infratest Dimap. It also shows 93% of respondents approve of the drastic social distancing measures introduced to try to contain the spread of the virus.

Germany has implemented a "contact ban," rather than a full nationwide lockdown. It has seen more than 84,000 confirmed cases, but its reported fatalities -- just over 1,100 -- have been lower than other major European countries.
