How it Spreads

How Does the Coronavirus Covid-19 Actually Spread?

How does the Coronavirus Covid-19 actually spread? Initial assessment in China was that is was not spread via human-to-human contact, then that was revised to state it can spread very quickly via human contact by breathing the infected air, to touching surfaces. Just HOW exactly is the Coronavirus spread, and how likely are you to catch it?

The Primary Way COVID-19 Spreads

CDC – Updated July 14, 2021

COVID-19 spreads when an infected person breathes out droplets and very small particles (aerosols) that contain the virus. These droplets and particles can be breathed in by other people or land on their eyes, noses, or mouth. In some circumstances, they may contaminate surfaces they touch. People who are closer than 6 feet from the infected person are most likely to get infected.

COVID-19 is spread in three main ways:

  • Breathing in air when close to an infected person who is exhaling small droplets and particles that contain the virus.
  • Having these small droplets and particles that contain virus land on the eyes, nose, or mouth, especially through splashes and sprays like a cough or sneeze.
  • Touching eyes, nose, or mouth with hands that have the virus on them.

Surfaces are NOT a Significant Way Covid-19 Spreads

Nature – 29 January, 20201: “the US Centers for Disease Control and Prevention (CDC) clarified its guidance about surface transmission in May, stating that this route (surface touching) is “not thought to be the main way the virus spreads”. It now states that transmission through surfaces is “not thought to be a common way that COVID-19 spreads”.

As evidence has accumulated over the course of the pandemic, scientific understanding about the virus has changed. Studies and investigations of outbreaks all point to the majority of transmissions occurring as a result of infected people spewing out large droplets and small particles called aerosols when they cough, talk or breathe. These can be directly inhaled by people close by. Surface transmission, although possible, is not thought to be a significant risk.

Experts say that it makes sense to recommend hand washing, but some researchers are pushing back against the focus on surfaces. In December, engineer Linsey Marr at Virginia Tech in Blacksburg co-wrote an opinion article for The Washington Post imploring people to ease up on cleaning efforts. “It’s become clear that transmission by inhalation of aerosols — the microscopic droplets — is an important if not dominant mode of transmission,” says Marr, who studies airborne disease transmission. Excessive attention on making surfaces pristine takes up limited time and resources that would be better spent on ventilation or the decontamination of the air that people breathe, she says.

Singing is No More of a risk in spreading COVID-19 than Talking

Aug 21, 2020 – The Christian Post: Singing at certain levels is no more likely to spread the Coronavirus than talking, according to a study released by researchers in the United Kingdom.

Researchers at the University of Bristol examined how much aerosols and droplets were generated by 25 singers who performed breathing, coughing, singing, and speaking exercises. The researchers found that while the aerosol mass produced rose steeply with an increase in volume of singing or speaking, singing did not produce substantially more aerosol than speaking at a similar volume.

Note that recently singing in churches has been targeted in Europe and the U.S. as particularly risky for spreading the Coronavirus Covid-19.  For example, in early May, Germany allowed for its churches to hold services, however, it came with a ban on handshakes and singing and also socially distanced attendance.  These singing bans have not been without controversy, as three churches in California sued Gov. Gavin Newsom in July over a similar prohibition.

Singing in church is no more risky than talking. If that is the case, any law or “order” against singing in or outside churches should be overturned immediately.
