incubation period in coronavirus is supposedly 2 to 14 days, but there are cases where it was equal to a month. This concept refers to the length of time from the moment of infection to the appearance of symptoms of the disease. The time a person begins to secrete enough infection to make their interaction a threat to the others is 24 hours before the symptomatic period.
incubation period of coronavirus in human is still being investigated. The incubation time is 5.1 days, according to data from US scientists. Within 11.5 days symptomatic of the disease appears in 97.5% of the sick. Therefore, a quarantine of two weeks is considered justified. Some scholars disagree in American ones. They insist that this time needs to be extended to 19 or 24 days.
On 10 February 2020, WHO, when asked how many days the incubation period is in coronavirus, noted: The 24-day time period may reflect double exposure (re-infection). The research that produced such data was decided to take in the context of the main conclusion.
JAMA in a study dated February 21 reported an incubation period of 19 days. A unique case occurred in Hubei Province. So at the man it lasted 27 days.
feature of COVID-19 is that the latent period is shorter than the incubation period. This means that the sick citizen becomes dangerous for those around him before the onset of symptoms.
The risk of getting viral infection is maximized at the stage of onset of symptoms, when it appears:
- elevated body temperature;
- dry cough;
- sore throat and other signs of SARI.
For the first time that coronavirus can be transmitted from person to person before the first signs of the disease appeared was stated by the head of China’s health department Xiaowei Ma. This announcement led to various controversies among American scientists. The case was compounded when such a case was described in the Lancet journal, and after the authors withdrew publication.
Japanese experts decided to investigate the contradiction. They checked the data for 26 small groups living at the center of the epidemic in St. Wuhan. In them, infection occurred in the first weeks of coronavirus. Studies have shown that each new case occurs three days after infection. This confirmed asymptomatic transmission of the virus was possible. On the basis of this, it was also concluded that the scale and speed of the spread had been underestimated, with serious consequences around the world.
