WHO says the coronavirus can spread one to three days before symptoms start
World Health Organization officials said the coronavirus can spread in asymptomatic patients, about one to three days before symptoms start.
“It’s very important to note that even if you are pre-symptomatic, you still have to transmit through droplets. You still have to have these infectious particles that come out of your nose and mouth,” Dr. Maria Van Kerkhove, the WHO’s team lead on the coronavirs, said at a press conference from the organizations Geneva headquarters on Monday.
She said models of the outbreak suggest that there are “large numbers of unrecognized transmission.” She emphasized those are unrecognized patients, not asymptomatic.
″ I’m saying we may be missing people who are out there who are infected but we’re missing them because of certain surveillance strategies,” she said.
WHO says coronavirus vaccine and treatment research has ‘accelerated at incredible speed’
“The viral genome was mapped in early January and shared globally which enabled tests to be developed and vaccine research to start,” he said at a press conference from the organization’s Geneva headquarters. He said more than 70 countries have joined WHO’s trial to accelerate research on effective treatments and “about 20 institutions and companies are racing to develop a vaccine.”
Dr. Mike Ryan, the WHO’s executive director for emergencies program, said one trial underway will look at prophylaxis in health care workers to see if there’s evidence of giving lower doses of drugs like hydroxychloroquine would reduce their risk of becoming infected in a health care environment.
