World Health Organization says coronavirus airborne transmission is possible indoors

As already reported, Dr. Trish Greenhalgh, a professor of primary health care at the University of Oxford said the WHO's new scientific brief is not convincing as it is clear that the members of the committee interpreted the evidence differently.

The team comprising an epidemiologist and an animal health specialist are flying to China to try and identify the pandemic's animal source, WHO spokesperson Margaret Harris said a United Nations press conference in Geneva.

Human immunodeficiency virus (HIV), the virus that causes AIDS, was often a fatal infection when it emerged in the 1980s, but today is considered manageable with antiretroviral drugs. As per the agency, "Infected people can transmit the virus both when they have symptoms and when they don't have symptoms", while earlier World Health Organization said that the asymptomatic transmission, while it may occur, was probably "very rare".

"We can not become distracted with retrospection and fingerpointing. This is a question we all need answered", she said. Droplets typically drop to the ground soon after they leave the mouth or nose of an infected person.

"Detailed investigations of these clusters suggest that droplet and fomite [surface] transmission could also explain human-to-human transmission within these clusters", the agency said, stressing that bad hand hygiene, a lack of adequate social distancing, and forgoing face masks could also all play a role in the spread.

The updated information came after hundreds of scientists and engineers drafted an open letter to the World Health Organization demanding it changes its stance on transmission, which had said the virus was spread by droplets that are much larger and heavier, and fall through the air faster, than aerosols.

In its latest figures posted on Friday, the WHO said there were 228,102 new cases across the world. In the letter published on Monday by the Journal Clinical Infectious Disease (Oxford Academic), the scientists said it is time to address airborne transmission of Covid-19.

Globally, there have been 1.25 million confirmed COVID-19 cases and almost 4.6 lakh deaths since the outbreak began late a year ago, according to data compiled by Johns Hopkins University.

Airborne transmission can be problematic in restaurants and bars, for example, where people are often maskless and thus more vulnerable.

The organisation's director-general, Dr Tedros Adhanom Ghebreyesus, has recently warned the global COVID-19 infection rate is accelerating.

He added, however, "I think it's a reasonable assumption that it does occur". "To be able to see if we can mitigate against that".
