CDC says its guidance that coronavirus spreads through the air was posted ‘IN ERROR’

The Centers for Disease Control and Prevention (CDC) says it mistakenly published guidance suggesting that the novel coronavirus spreads through the air. 

”A draft version of proposed changes to these recommendations was posted in error to the agency’s official website,’ the agency in a statement, according to CNBC

‘CDC is currently updating its recommendations regarding airborne transmission of SARS-CoV-2 (the virus that causes COVID-19). Once this process has been completed, the update language will be posted.’ 

The World Health Organization (WHO) said it contacted the CDC earlier on Monday about the update.

It comes days after the CDC changed its controversial recommendations that people exposed to COVID-19 who are asymptomatic forego testing.

Airborne viruses ‘are among the most contagious and easily spread’, the CDC had warned, while advising people to use air purifiers to clean the air in indoor spaces, in addition to wearing masks, washing hands, and isolating if you are sick.

The agency said the virus spreads ‘through respiratory droplets or small particles, such as those in aerosols, produced when an infected person coughs, sneezes, sings, talks or breathes’. 

Previously, the CDC advice said that coronavirus is spread ‘through respiratory droplets produced when an infected person coughs, sneezes or talks.’ 

‘There is growing evidence that droplets and airborne particles can remain suspended in the air and be breathed in by others,’ the guidance says.

‘[These particles] travel distances beyond 6 feet (for example, during choir practice, in restaurants, or in fitness classes). 

‘In general, indoor environments without good ventilation increase this risk.’

The move comes after the World Health Organization changed its own guidelines in July to acknowledge that it ‘is possible’ to become infected by airborne transmission.

However, both the CDC and WHO still say that close and prolonged contact with an infected person is the most common way that the disease spreads.  

A growing body of scientific evidence suggests that the virus can survive in the air on much smaller droplets that are expelled even when a person breathes.

Because the droplets are so small they do not fall to the floor right away, and instead linger in the air where they can be breathed in by others.

The fact that the droplets linger also means they can drift further than six feet away from an infected person, potentially passing the disease along to someone who was never in close contact with them.

Evidence that the virus is airborne will alarm world leaders who had based their prevention strategies on the assumption that the virus could not spread across large distances (pictured, reporters socially distance at a Joe Biden rally)

Measles and tuberculosis can be spread via aerosols, and are considered highly infectious.

Wearing masks helps to prevent against airborne diseases – with world governments now increasingly adopting such measures as the science changes. 

The WHO changed its guidance after 239 scientists in 32 countries wrote to the UN agency asking it to acknowledge the growing evidence the virus is airborne. 

One professor who signed the paper said there will be concern to label the virus airborne because it may cause panic.

Benedetta Allegranzi, the WHO’s technical lead for infection prevention and control, acknowledged at the time that evidence of airborne transmission was emerging -but that it still needed to be carefully studied.

‘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.’

The novel coronavirus, or Covid-19, was first detected in Wuhan, China, at the end of last year when it caused a cluster of infections centered around a seafood market.

Since then it has spread rapidly to almost every country on earth, infecting more than 31million people, according to a WHO tally.

The US is the world’s worst-hit country with 6.8million infections, though India – with 5.4million – has the world’s fastest-growing outbreak and is due to overtake it in the coming weeks.

Almost 1million people have died from the disease worldwide, according to official counts, though this is widely believed to be an under-estimate.  

Ongoing problems with testing even in developed countries means that, often, only patients with severe infections are able to have a diagnosis confirmed.

This is significant because many patients are thought to exhibit only mild symptoms or no symptoms at all. 

This is thought to be a majority of cases, though evidence around asymptomatic infections remains unclear.

The US has also suffered almost 200,000 deaths from the virus which is by far the highest global total. The next-highest is Brazil, which has recorded 136,000.
