Cycling, especially road cycling, means being closely packed with riding companions or competitors for hours. But the coronavirus has changed all that. As the potentially deadly Covid-19 pandemic has escalated across the globe, cyclists wonder, "Is it safe to ride outside together?" Cyclingnews looked at the science and can only co⛄nclude that no, you should not, and in fact, you really sh🌸ould just stay home.
A new study in the New England Journal of Medicine ha🌞s given some grave evidence that the coronavirus can remain viable on surfaces for days and can be transmitted by people with no symptoms. Most countries are lagging woefully behind in testing, and some countries have basically given up on trying to identify all infected individuals.
In the United States, most states are discouraging heal𝔍thy people from seeking tests to keep them away fro𒊎m doctors offices or hospitals with a potentially high number of infected people.
You can be infected and not know it, like the Republican Senator 𝓀from Kentucky, R🐬and Paul, who, asymptomatic, went to the Senate gym and swimming pool to work out, then got his positive coronavirus test results a few hours later.
The science
The , done by researchers at the National Institute of Allergy and Infectious Diseases and University of California in Los Angeles, compared the survival of the previous SARS coronavirus, SARS-CoV-1🦩, to the new virus that emerged in China in Decem𒁏ber, SARS-CoV-2, in the air and on surfaces.
They simulated cough droplets by spraying a virus solution through a nebuliser (similar to an asthma inhaler) and measuring how many infectious particles t▨hey found at time points over three hours.
Like its predecessor, SARS-CoV-2 remained in the air atಌ infectious levels in laboratory conditions (65% humidity and temperatures of 21-23°C) "throughout the duration of our experiment (3 hours)", they wrote.
Rachel Bender Ignacio MD MPH, an infectious disꦫease specialist from Seattle🎐, clarified that there is plenty of evidence the virus is not spread person to person in aerosols, but is transmitted through larger droplets when people cough or sneeze and then pick it up by being in close proximity or from surfaces near where an infected person coughed or sneezed.
Disease control experts say six feet away is enough to avoid picking up the virus from an infecte𝔍d person, but Bender Ignacio says, "There is no science to know what distance you need🐻 in a slipstream" and advises against group rides.
Two oth𒐪er studies have shown evidence that asymptomatic SARS-CoV-2-infected people are capable of transmittin൲g the virus because they have the same amount of virus particles in their lungs.
"The viral load that was detected in the asymptomatic patient was similar to that in the symptomatic patients, which suggests the transmission potential of asymptomatic or minimally symptom♎atic patients," a .
The two studies point towardܫs cycling outside with others not in your living unit, even two metres apart from each other, not being a good idea - at the very least because if you are injured you might need to go to a hospital where the , and you might find .
But Bender Ignacio hopes people will continue to be smart and cycle solo or with their family unit, taking extra care to not crash because exercise is goඣod for the immune system.
Spain, France, Andorra and Italy have discouraged people fr🔯om going outside, with varying degrees of punishment for violations because ಞpeople naturally gathered in groups. The best action is to listen to what your officials tell you to do.
The better we are at keeping off the streets, away from anyone but your family or living compani🌳ons, the quicker we can end the pandemic and get back to racing. We are all in this together, so please be smart, stay safe, stay healthy, and ride the trainer.
This article was revised on March 24, 2020 to clarify the unlikelihood of being infected from particles in the air whilst cycling solo, well away from others.
