New data show that asymptomatic COVID 19 infections are rare.
People without classic symptoms are not primarily the carriers of the coronavirus pandemic. This was announced by the World Health Organization (WHO). The WHO also doubts that COVID-19 is difficult to contain due to asymptomatic infections.
People who show no symptoms or only weak symptoms may indeed transmit the disease, according to the WHO. However, this is not the most common source of transmission.
Contact tracing is effective
“The data available to us show that it seems rare for asymptomatic individuals to infect others,” said Maria Van Kerkhove of WHO at a press conference. “In fact, it is very rare,” she added.
Governments should therefore focus their efforts on identifying and isolating infected individuals who show classic symptoms. Contact tracing of infected persons is also an effective way of containing the pandemic.
“We have detailed reports from countries that maintain a very accurate contact tracking,” says Van Kerkhove. “They also follow up contacts of asymptomatic cases and find hardly any secondary transmissions. This is very rare.”
However, Van Kerkhove says more studies are needed to fully understand how COVID-19 is spreading.
