No Proof Yet That Asymptomatic COVID-19 Carrier Can Infect Other People

Health Secretary Francisco Duque III said that there is still no evidence to prove that individuals positive for the novel coronavirus disease, COVID-19 but are asymptomatic can infect other people, as he quoted the World Health Organization (WHO). Duque made the comment in a Senate hearing on the novel coronavirus pandemic after he was asked about the strategies of the Department of Health in detecting people who don’ manifest symptoms or “silent spreaders” of this deadly respiratory disease.

In a report, the WHO said that to date, there have been no reports of asymptomatic transmission. This does not exclude the chances that it may transmit. Asymptomatic cases have been reported in some countries as part of contact tracing efforts. Meanwhile, the study by Chinese researchers found that pre-symptomatic carriers of COVID-19 can contaminate other people and their environments. But, Duque said that it is very difficult to detect asymptomatic coronavirus carriers. He explained that local authorities have been entrusted with monitoring people suffering from a severe acute respiratory infection and influenza-like illness.

Everyone should take extreme care against the droplets that might come out when a person sneezes or coughs. In the case of a coronavirus patient, these droplets could be the direct source of infection. That is why all health officials urge people to use a face mask whenever they go in public.

The novel coronavirus can also spread through standard exhalations that could carry small droplets that could contain the deadly coronavirus. Though many people don’t believe this a regular breath could also help in spreading the contagious virus to several feet.

It could also spread from common surfaces, such as an ordinary-looking cart handle at your nearest grocery store or a doorknob of a pharmacy. If an infected person has touched them, there is a high chance of the virus being passed to the next person who touches it.

If you suspect of being exposed to anyone who has this deadly virus, it is necessary to go into a self-quarantine even if you don’t develop any symptoms. the typical time for this period is 14 days and this period is sufficient to see if a person develops coronavirus symptoms or not.

In Washington, many residents became infected in a nursing home. Twenty-three people tested positive for the novel coronavirus. Ten of them were already sick and eventually, ten more people also developed symptoms. But three of the individuals who tested positive had not complained about any symptoms of the illness.

In Boston, doctors tested 397 people who were staying at a homeless shelter and found that 36% of them tested positive for the novel coronavirus and none of them had experienced any symptoms. Similarly, in the case of Japanese citizens who were evacuated from Wuhan and tested for the novel coronavirus, 30% of those infected people were asymptomatic.

An Italian study that has not yet been peer-reviewed revealed that 43% of those who tested positive for coronavirus illness showed no symptoms. The researchers found no difference in how potentially contagious individuals with and without symptoms were, based on the titer of the virus in the samples of the infected people. The antibody serosurveys conducted in different parts of the country add further evidence that the good number (around 10% to 40%) of the infected people might not experience any symptoms. Asymptomatic coronavirus infection appears to be common and this will continue complicating the efforts to control the COVID-19 pandemic.
