The recent outbreak of the coronavirus in China has sparked global concern and panic, and for good reason.

The virus, which originated in the city of Wuhan, has already claimed the lives of 26 people and infected over 800 more. But what makes this outbreak particularly alarming is the fact that the virus can spread before symptoms even show.

Scientists and health officials have long believed that the virus, known as 2019-nCoV, is transmitted through respiratory droplets when an infected person coughs or sneezes. This is similar to how other common respiratory illnesses such as the flu are spread. However, a recent study published in the New England Journal of Medicine has revealed that the virus can be spread even before an infected person starts showing any symptoms.

According to the study, a woman from China had traveled to Germany and came in close contact with a colleague before she started experiencing any symptoms. Later, it was discovered that she had been infected with the coronavirus. What is even more concerning is that the woman did not have a fever or any respiratory symptoms during her initial contact with her colleague. This suggests that the virus can be transmitted even when an infected person appears to be healthy.

This finding has major implications for the containment of the virus. Health officials have been relying on screening and quarantine measures to prevent the virus from spreading. However, with the knowledge that the virus can spread before symptoms show, it becomes even more difficult to control its spread. Infected individuals who are not yet showing symptoms may not be aware that they are carrying the virus and continue to go about their daily activities, potentially infecting others.

Furthermore, the incubation period of the virus, the time between being infected and showing symptoms, is believed to be up to 14 days. This means that an infected person can be spreading the virus unknowingly for up to two weeks before realizing they are sick.

The Chinese government has taken drastic measures to try and contain the outbreak, including shutting down transportation in and out of Wuhan and other affected cities, and canceling major public events. These measures are in line with the World Health Organization’s (WHO) recommendations, but with the new information about the virus spreading before symptoms show, it is unclear how effective these measures will be in preventing further spread.

The WHO has declared the outbreak a public health emergency of international concern and is urging countries to take action to contain the virus. The United States has already implemented screening measures at major airports for travelers coming from Wuhan, but with the knowledge of pre-symptomatic transmission, some health officials are calling for even stricter measures, including quarantining all travelers from affected areas.

As the virus continues to spread within and outside of China, it is important for individuals to take precautions to protect themselves and others. Frequent handwashing, avoiding close contact with sick individuals, and wearing masks in public can help prevent the spread of the virus. Anyone who has traveled to Wuhan or has come in close contact with someone who has, and is experiencing symptoms such as fever, cough, or difficulty breathing, should seek medical attention immediately.

While there is still much to learn about the coronavirus and the extent of its transmission, this recent discovery of pre-symptomatic spread highlights the urgent need for continued research and containment efforts. In the meantime, it is essential for individuals to stay informed and take necessary precautions to protect themselves and their communities.
