Specialists noticed that the re-infection of the coronavirus is characterized by a lower viral load compared to the first infection, which leads to weaker symptoms. This may indicate that COVID-19 can turn into a relatively light respiratory disease. This is reported by Sky News.
According to a survey conducted by the Office of National Statistics (ONS) in the UK, 195 people were subjected to coronavirus people of re-infection. At the same time, only in 48 cases the viral load was high. Such people had classic symptoms of COVID-19, for example, cough, fatigue or headache. In other cases, patients reported the loss of sense of smell and violation of the gastrointestinal tract.
Scientists also compared the viral load during the first infection and re-. If for the first time the average value of CT was 24.9, then the second time it rose to 32.4. CT shows how much the cycles of the polymerase chain reaction are necessary to identify the presence of the coronavirus. A higher CT value corresponds to a smaller viral load. Infected people with a lower viral load with a smaller probability will get sick and distribute the virus.
even taking into account the increased risk created by mutant strains, such as the delta version of the coronavirus, the number of re-infected British remains low. Thus, immunity, which remained after illness or vaccination, can contribute to the mitigation of COVID-19 and the gradual fading of the pandemic.
