“Delta” -variant coronavirus has symptoms that differ from other SARS-COV-2 options. If earlier the characteristic signs of the disease were cough, fever, shortness of breath and loss of smell or taste, then a runny nose became more common, the throat and headache. Reports about it The Telegraph.
The most typical symptom of COVID-19 in Britain, where “Delta” -varizes all other options for Coronavirus, became a headache, which is observed in two people of people under 40 years old (as well as more than half of 40 years) infected by Sars- COV-2. The following prevalences are classic cold symptoms: runny nose and throat pain. Half of those younger than 40 years old, and a third of older people reported both signs of the disease.
According to doctors, the headache at COVID-19 has characteristic features by which the infection can be distinguished from a conventional cold. Pains are moderate or strong, last 3-5 days on average, and painkillers do not improve well-being. Patients describe that the pain covers both sides of the head and is felt as a grace, pulsating or acute. At the same time, the symptom may appear earlier and last for a long time in people with a long course of COVID-19. Approximately 15 percent of the diseases do not have other symptoms.
As for the runny nose, when the level of propagation of coronavirus among the population was low, it was considered an unusual symptom, and with a greater probability could be caused by cold or allergies. Now the runny nose due to COVID-19 is more likely than for other reasons. Therefore, with any signs of ARVI, experts advise to stay at home and, if possible, to do a test for coronavirus.
Indian strain SARS-COV-2, apparently, is mostly striking young people who have not yet passed complete vaccination. They have lighter symptoms, because of which it becomes difficult to distinguish the cold and COVID-19.
