Asymptomatic COVID-19 transmission is very rare says WHO: A myth or truth?
With COVID-19 showing no mercy, and the number of confirmed cases increasing around the world, it is important to find the truth behind the transmission of asymptomatic cases.
As the number of COVID-19 cases rising every day, it is important to establish the difference between asymptomatic and symptomatic cases.
World Health Organisation head of COVID-19 pandemic department Maria Van Kekhove on June 8th made a statement stating that the chances of Asymptomatic COVID-19 transmission are very rare. Though this is completely not true she further added that around 16% of the asymptomatic cases can infect people and spread the virus.
“We do know that some people who are
asymptomatic can transmit the virus on,” Van Kerkhov said on Tuesday.
Symptomatic Vs Asymptomatic:
A mystery more of an oddity how easily people can get infected from someone who does not portray any symptoms. An asymptomatic transmission is when the virus infects the people, but due to strong immunity, the affected person will never showcase any symptoms from the infection. It should be noted, though no signs of symptoms, the affected person is very much a carrier of the virus and can potentially spread it to others, if not precautionary.
There is also a possibility of pre-symptomatic cases, where the person infected might show the symptoms later deeper into the virus life cycle. Studies suggest pre-symptomatic spread is more
common than asymptomatic spread. By the way of definition, a symptomatic case is when a person has full blow developed signs and symptoms that occur along with the COVID-19 infection.
Data from the Centre of Epidemiology and Virology Studies prove that COVID-19 is easily transmitted to other people who are in close contact with the affected or by contact with any contaminated surface or
objects. Such cases start showing symptoms in the first 3 days of the virus onset. Some studies suggest that there are higher chances of the virus being contagious during the initial stages.
A myth or a truth:
With its official statement “asymptomatic spread appears to be rare” WHO has confused experts and doctors that have been trying to prove the opposite for months.
“The WHO comment was incorrect,” said Dr. Anthony Fauci, a top infectious disease expert in the US. Evidence from previous studies prove that 25% to 45% of infected people likely don’t have symptoms, but from epidemiological studies, it can be seen that they are capable of infecting people even without symptoms.
Previous research performed on asymptomatic cases has reported mixed results, proving no solid evidence of what proportion of people are being infected by asymptomatic transmission. While everyone right now using the world asymptomatic to describe an infected person, the bigger concern is regarding people suffering from pre-symptomatic COVID-19 cases.
Van Kerkhove later released a statement and emphasized that the information she’d shared on the previous day was based on a handful of studies that had tracked spread among known asymptomatic cases, and stated that she had not intended to imply that “asymptomatic transmission globally” was uncommon.
