Coronavirus: How long do Covid-19 symptoms last and how fast it develops? (2023)

Until now, I hope that everyone knows the main symptoms of Covid: fever of approximately 37.8 ° C, new and continuous cough and loss of (or a new change) of the smell and/or taste. However, there is still a lot of confusion aboutThe speed at which exposure to Virus Covid symptoms develop and what can expect if it is infected.

Let's start with a warning: it seems that Covid -19 already exists forever, but this is still a relatively new illness and the evidence.

In the first weeks after the fact that a country is affected or a new wave of cases occurs, there is usually a hospital care and an intensive care unit (ICU). The observation hospital can be treated at homeIn the intensive care unit could have been ventilated, keep them in operation; and the UCI ventilation is reserved for the patient.

In fact, it is clear from the first wave of pandemic that the results are better for most patients if mechanical ventilation can be avoided.Nurse 'Propenso'(Las due to the fronts) as much as possible, and the delay of mechanical ventilation, when it is viable, became accredited at least with improved survival rates of the first wave.

Things to do even more confusing, definitions ofLight, moderate and severe infectionThey also vary between the countries.

All of these variables make it impossible to offer a completely accurate average time for hospital entry or the average time before restoring the intensive care unit.Report of the World Health OrganizationChinese experience.

Incubation: How long does it take for Covid symptoms to start?

The incubation period of an infection is the time between the exposure and development of COVID symptoms. There are several challenges when preparing the incubation period for the coronavirus:

  • It is not always possible to know when people are infected for the first time for the first time, especially if they have received several doses viruses.
  • There seems to be a significant differences in time that leads to people develop symptoms.
  • Some countries prove (and confirm) Coronavirus only in people with severe infection, and it is not known whether the incubation period is different for people with critical/severe/moderate/light/light infection.
  • It is assumed that many people do not develop symptoms (they are "asymptomatic"), so there are no symptoms to say.

However,A studyHe analyzed confirmed cases of 50 provinces, regions and countries outside of Wuhan in which it was possible to identify a single source of infection. They discovered this:

  • The average incubation period (half of all cases occurs before these half)5,1 Dias.
  • 97,5%From people who develop symptoms, they have inside11,5 Dias.

In people with a more difficult infection, it is likely that the lack of breath will be more pronounced7-10 days after the development of symptomsThis happens because the infection deepens the lungs, which leads to inflammation, which avoids the efficient oxygen transmission of the lungs to the bloodstream.
