The World Health Organization (WHO) says it will take time to send additional experts to China to investigate Corona19 origin.

According to the Associated Press, WHO Deputy Secretary for Emergency Preparedness Michael Ryan said it is unrealistic to expect a further dispatch of the investigative team within a month at a video press briefing held at the WHO headquarters in Geneva, Switzerland at local time.

Earlier, on the 10th, WHO sent two selection teams of epidemiologists and animal health experts to investigate Corona 19 origins in China.

However, the WHO says they are in quarantine at a hotel in Beijing, according to procedures, and that Corona 19 has no plans to visit the first reported Wuhan.

Deputy Secretary-General Ryan also said that in Brazil, where Corona 19 damage is severe, the spread is "no more exponential," so as not to miss the opportunity to control the epidemic, Reuters reported.

In addition, 11% of all infected people in Brazil said they were medical staff.

"We all owe too much to the medical staff," said WHO secretary-general, Theodros Adhanom Governor Yeosu, and said that the WHO is coordinating research to improve its understanding of the risk of infection.
