     In recent days, there have been many questions about COVID-19: What is COVID-19? How does it work? How are the people affected by it and the severity of its illness? It spreads fast or slowly …

     Among the most important questions to answer is how long does it take for people with SARS-CoV-2 infection (the virus that causes COVID-19) to develop symptoms? This process is known as the incubation period, which is critical for implementing effective preventive and preventive measures.

     A new study, published in the Annals of Internal Medicine, provides new estimates that are largely consistent with other early epidemiological studies. Accordingly, the average incubation period of the COVID19 virus appears to be about five days, with the vast majority developing symptoms within twelve days.

     The number of incubation days “will definitely be more determined when we have more information,” said Justin Lessler, lecturer in infectious disease epidemiology at Johns Hopkins Bloomberg School of Public Health, co-author of the study. our early vision “is important to think of control measures such as quarantine and active surveillance.”

     The US CDC isolates those suspected or confirmed to have COVID-19 for fourteen days, based on the assumption that the average incubation period of the disease is about a week and therefore, almost all Viral infection will appear symptoms over a period of fourteen days.

     Although there have been reports of incubation periods longer than fourteen days, a new study estimates that about 1% of the 10,000 patients will develop symptoms after two weeks of follow-up. At this point in time, when the United States is no longer able to completely stop the spread of COVID-19, its public health agencies may have to live with that risk.

     “Now the virus is present in more places in the United States, perhaps reducing risk and slowing things down is a better strategy than making the quarantine even stronger.” Lessler said. “Quarantine is not inexpensive, especially on medical staff.

     The team’s estimates are based on 181 confirmed COVID-19 cases from January 4 to February 24, 2020. Most cases are in people who have been to Wuhan, China, where the outbreak outbreak. Determining exactly when each person is ill requires a certain level of education. Where possible, researchers rely on specific sequences of events, interactions, or activities that can lead to infection to calculate the delay from exposure to onset of symptoms.

     Lessler stressed that it is still early to collect data on disease outbreaks, especially in the US, where large-scale testing has just begun. But as more data on incubation period, mortality and other aspects of the epidemic, clinicians will have a firmer idea of what they’ve been up against.
