WHO acknowledges ‘evidence emerging’ of airborne spread of COVID-19

  • WHO previously said the virus spreads through droplets expelled from the nose and mouth that quickly sink to the ground
  • New evidence shows floating virus particles can infect people who breathe them in

GENEVA: The World Health Organization on Tuesday acknowledged “evidence emerging” of the airborne spread of the novel coronavirus, after a group of scientists urged the global body to update its guidance on how the respiratory disease passes between people.
“We have been talking about the possibility of airborne transmission and aerosol transmission as one of the modes of transmission of COVID-19,” Maria Van Kerkhove, technical lead on the COVID-19 pandemic at the WHO, told a news briefing.
The WHO has previously said the virus that causes the COVID-19 respiratory disease spreads primarily through small droplets expelled from the nose and mouth of an infected person that quickly sink to the ground.
But in an open letter to the Geneva-based agency, published on Monday in the Clinical Infectious Diseases journal, 239 scientists in 32 countries outlined evidence that they say shows floating virus particles can infect people who breathe them in.
Because those smaller exhaled particles can linger in the air, the scientists are urging WHO to update its guidance.
Speaking at Tuesday’s briefing in Geneva, Benedetta Allegranzi, the WHO’s technical lead for infection prevention and control, said there was evidence emerging of airborne transmission of the coronavirus, but that it was not definitive.
.”..The possibility of airborne transmission in public settings — especially in very specific conditions, crowded, closed, poorly ventilated settings that have been described, cannot be ruled out,” she said.
“However, the evidence needs to be gathered and interpreted, and we continue to support this.”
Any change in the WHO’s assessment of risk of transmission could affect its current advice on keeping 1-meter (3.3 feet) of physical distancing. Governments, which rely on the agency for guidance policy, may also have to adjust public health measures aimed at curbing the spread of the virus.
Van Kerkhove said the WHO would publish a scientific brief summarising the state of knowledge on modes of transmission of the virus in the coming days.
“A comprehensive package of interventions is required to be able to stop transmission,” she said.
“This includes not only physical distancing, it includes the use of masks where appropriate in certain settings, specifically where you can’t do physical distancing and especially for health care workers.”


Civilians, soldiers clash leaving 127 dead in South Sudan

Civilians, soldiers clash leaving 127 dead in South Sudan

  • The violence in Tonj began after several armed youths got into a disagreement with soldiers
  • An initial armed confrontation was brought under control, but local youths subsequently mobilized for an attack on the army position

JUBA: Clashes between soldiers and civilians during a disarmament exercise in the central South Sudanese town of Tonj have left 127 dead, the army spokesman said Wednesday.
Major General Lul Ruai Koang told AFP that the fighting erupted on Saturday as security forces carried out an operation to disarm civilians in the area which has seen deadly inter-communal clashes.
More than six years after a civil war broke out in the country, and in the absence of a functioning government, many communities are flush with weapons, which they keep for protection or defense against cattle raids.
The violence in Tonj began after several armed youths got into a disagreement with soldiers. An initial armed confrontation was brought under control, but according to Koang the youths mobilized others for an attack on the army position.
“On the latest, the number of those killed, I can confirm to you that it rose to 127,” Koang said, adding that 45 of those killed were security forces and 82 were youths from the area.
A further 32 soldiers were injured.
Koang said two military officers involved in “triggering the clashes” had been arrested, and that the situation in Tonj had calmed down.
South Sudan is emerging from a six-year civil war that left 380,000 dead and millions displaced, and disarmament is a major stumbling block.
Experts have warned against operations that coerce people to lay down their guns without proper planning, as some communities could find themselves unable to protect themselves after their weapons are removed.
“The clashes should be an opportunity to rethink the approach to disarmament. What is the point of removing guns without addressing what drives folks to arms themselves?” Geoffrey Duke, head of the South Sudan Action Network on Small Arms, said on Twitter.
“We can take guns away this week & they buy a new one next week (as) long as they still see the need to have (one).”
