Contagious COVID-19: Is It More Dangerous Before Symptoms?

Contagious COVID-19 is today’s deadly issue. The coronavirus responsible for COVID-19 is particularly contagious. A new study found that it can be more deadly in the early stages of infection. Yes, it can be more contagious and deadly even before people report symptoms. A fact that should be taken into account is to fight against its spread. And obviously, we know how we can prevent contagious COVID-19 from spreading.

Researchers and experts have already chalked down different measures. The measures include on how to slow the spread of the coronavirus responsible for the COVID-19 pandemic.

Contagious COVID-19: A Chinese Study

To make them even more effective, researchers are trying to determine under what conditions the virus can transmit. They also regulate at what stages the disease may turn into a devastating one. A new study by researchers at the University of Guangzhou (China) now reports that contagiousness may peak before a person reports symptoms.

The study involved 77 pairs of infected patients admitted to Guangzhou hospital between January 21 and February 14. They show that virus production may be highest in the early stages of infection, before the immune system intervenes to eliminate viruses and produce symptoms. Thus, an individual becomes contagious 2.3 days before the onset of symptoms. And its contagiousness peaks at 0.7 days, always before the onset of symptoms.

Adapting Measures To Control Contagious COVID-19 From Spreading

German researchers had come to a similar conclusion by isolating the virus and genetic material from patients. They found that only nine of them – their work had shown that an infectious version of the virus is produced before the onset of symptoms and during the first week of illness.

Thus, the researchers recommend that measures are taken to limit the spread of the coronavirus. And it should adjust according to this substantial pre-symptomatic or even asymptomatic contagiousness. For example, it would not be sufficient to search for patient contacts from the day they reported symptoms. It is indeed necessary to go back at least two or three days earlier.

Coronavirus: Contagion Before Symptoms Occur, WHO Says

The World Health Organization (WHO) is still working to understand the mode of transmission of the Chinese virus. Are people infected with this COVID-19 contagious or not before the first symptoms appear? The Chinese authorities, for their part, have affirmed this.

The question of whether or not people infected with the coronavirus/COVID-19 that emerged in China are contagious before the first symptoms appear remains, the World Health Organization (WHO) said that the virus, which is causing an epidemic of pneumonia, has already killed many lives around the world.

Incubation Period Still Uncertain

In a recent report on this new virus, called 2019nCoV, the UN agency estimates its incubation period at two to ten days. “Understanding when infected patients are likely to transmit the virus is essential to better control it,” the WHO says. But the organization has not yet confirmed claims by Chinese authorities that infected people can infect others even before the first symptoms of fever or lung disease appear.

“Detailed epidemiological information on many more people infected with the virus is needed to determine the period of infection of 2019nCoV, particularly whether transmission can occur from people who show no symptoms or during the incubation period of the virus,” WHO said.

Contagious COVID-19:  A Very High Threat Internationally

In recent days, Tedros Adhanom Ghebreyesus, the director of WHO says that COVID-19 is a very high risk internationally. We can even understand this from the reports around the world.

The new Chinese virus is of concern to health authorities because it is reminiscent of a previous virus, SARS (Severe Acute Respiratory Syndrome). It also appeared in China and was transmitted by animals, causing hundreds of deaths in China and Hong Kong between 2002 and 2003.

This contagious COVID-19 appeared in a market in Wuhan, China. According to the Chinese source, animals transmitted it to humans. However, it has since spread from human to human without its exact mode of spread being clearly identified. Whether it transmits from animal to human, or it transmits from the Chinese lab is still a controversy.
