WHO scientific brief on COVID-19 transmission


WHO issued an updated scientific brief on COVID-19 transmission, which provides information on how, when and in which settings the virus spreads between people.

COVID-19 transmission occurs primarily through direct, indirect or close contact with infected people through their saliva and respiratory secretions, or through their respiratory droplets, which are expelled when they cough, sneeze, talk or sing.

Airborne COVID-19 transmission can occur in health care settings where specific medical procedures generate very small droplets – aerosols.

Some COVID-19 outbreak reports related to crowded indoor spaces have suggested the possibility of aerosol transmission combined with droplet transmission e.g. during choir practice, in restaurants or gyms. We need more studies to understand such outbreaks: https://bit.ly/2W251Ma

Respiratory droplets from infected individuals can also land on objects or other surfaces. It is likely that people can also be infected with COVID-19by touching these surfaces & touching their Eyes, Nose or Mouth before cleaning their Open hands.

Based on what we currently know, COVID-19 transmission primarily occurs when people are showing symptoms, but can also happen just before they develop symptoms – when they are in close proximity to others for prolonged periods of time.

While people who never develop COVID-19 symptoms can also pass the virus to others, it is still not clear to what extent this occurs. More research is needed in this area.

Urgent research is needed on:

-transmission routes
-airborne transmission in the absence of aerosol generating procedures
-dose of virus that will result in infection
-settings and risk factors for superspreading events
-extent of asymptomatic and pre-symptomatic transmission

  1. Come on people why aren’t these people in jail already and this crooked incompetent organization dissolved yet……they are playing games with humanity, 6 months of a plandemic where no one extra has really died no one is dropping dead, she is only saying this information because they are going to poison us more or they are getting ready to turn on the 5G which is going to hurt a lot of electrically sensitive people, then they will blame it on virus that doesn’t exist. Wake up

  2. The US does not formally withdraw from the WHO. This is a fascist lie from the criminal hard-right occupation of the US Federal government. They are not legitimate. They were not elected. They do not rule with the consent of the citizens. We US citizens demand that this criminal US Federal Administration be arrested and prosecuted by the International Criminal Court at the Hague and we implore all upstanding civilized peoples of the world to come together to aid us in this most urgent and necessary purge of corruption and treason from our liberal democratic system for the sake of all humanity. Any nation, any media voice, that claims the US has withdrawn from the WHO is a fascist collaborator and must be punished for their betrayal of all humanity.

  4. Complete Bull Shit!!! I have first hand experience with this so called pandemic and it’s all crap! Just stop now, this pandemic is officially over people let’s get back to our lives and shut these people down. They can no longer control the human race…

  5. Respected Doctors,👏🏾As You Rightly Pinpointed the overloaded &
    adulterated poor quality of mushrooming papers in name of research on COVID19 & to consider carefully . The billions of people believe W.H.O will save us from this catastrophic pandemic by SCIENTIFIC GUIDELINES. CHANGE IS THE ONLY CONSTANT IN THIS WORLD.

  6. if its airborn masks r useless…social distancing is useless…staying outside or in a well ventilated indoor space is important…

  7. WORLD HEALTH ORGANISATION has allowed china to cover-up coronavirus, all funding should be pulled and china must be placed accountable for key failures that allowed such virus to escape if it was intentional which is most likely as Chinese internal flight grounded and external flights carried on. CCP is the most dangerous country present they’ve proved that with the erosion of hong kong high autonomy of freedoms and the South China Sea invasion where they are claiming millions of miles of sea that belong not just china but Vietnam Philippines Indonesia, 1 million Muslims locked up prison camps, border standoff, etc. the list is endless of Chinese lack of respect and integrity to world peace and prosperity. the true enemy of the free world and must punished with tariffs and market restriction and if that means banning Huawei and TikTok so be it.

  9. Dear WHO, common sense, not 100% scientific proof is needed here. Your thinking is upside down. There will never be 100% certainty with this issue & by the time you get it—if you ever do, many more people will die. Masks cannot hurt people (except their dignity)—they can only possibly help. We know they create some sort of barrier. Better to be safe, than sorry. If the virus is later found to not be as airborne as thought, so be it. An abundance of caution is needed. Just say “we are not 100% sure yet, but wish to protect people as best as possible”!

  10. Hello. I found statistics (“Lithuania Covid 19 statistics), when in the country do not died any person even due Covid 19… When in Lithuania’s local statistic “Covid 19 Deaths in Lithuania (Covid 19 Mirtys Lietuvoje)” is number 79 (by the way – it is the very big percent even from the infected persons number (over 1800). WHY SUCH YOUR LIE..? By the way… I do know cases (persons were probably infected of the Urgent Medicine Services… Nah… Ambulance’s), in Klaipėda, an example, when such deaths do mot were announced. Such cases – appeared team of Urgent Service and do offered a simple healing… Such person do received the very big troubles after and… when he was by his death delivered to Klaipeda’s hospital, was found Covid 19, but – it w do not announced, as the death due Covid 19… The same – such case in Ukmerge, when human was simple left by hospital, till he died… IT WAS THE 1’th DEATH DUE COVID 19 EVEN (..! it was announced later..), BUT… Does not figures in statistics, as “the too late correction…”…

  11. This virus has been around for months and so contagious and only NoW does who investigate if it’s airborne. 🤔 interesting.

  12. WHO, a corrupt organization. Only listen to them if you are planning on believing the opposite. Agenda agenda agenda.

  13. No one outside WHO has the time, energy or patience for you to figure out the perfectly right way to protect people from this disease, and everybody knows we are way past the “Let’s not create a panic” phase.
    What’s so bad about assuming the worst?
    WHO, you people are hired by every tax payer around the world to protect them from the worst!
    You could simply say “We want everyone to assume this virus is airborne”, and even if you are wrong about this, you’ll still get to say “Great news! We were wrong but we are safer than we thought”.
    You failed to do this in the beginning and allowed the virus to spread around the world. PLEASE stop wasting tax payer’s money and stop letting us down.
    They will otherwise stop listening to you – some would say they already have.

  14. I don’t believe those satanicguyssss anymore, like killgateandfaucini SorosandChina 👎 plandemicccc coronacircusssss

  15. To go for routine corona test mandatory for passengers may be hazardous for community transmission. It may be counter productive. When healthy peope will go to those testing facility’s, they may be exposed to viruses and afterwards before they get symptoms, they will be spreading the virus among other passengers of the aircraft
    Please, think twice before doing this.
    What WHO suggests?
