Omicron variant, mild symptoms and incubation lasts 3 days: what we know

Lighter symptoms, faster incubation. The identikit of the Omicron variant is increasingly clear, which also in Italy increases covid infections up to a record of 98 thousand abundant cases. Studies on the new coronavirus mutation follow one another, the data are analyzed and the picture is outlined. The symptoms, unlike the traditional covid, are milder and – if we want – various: from the cold that recalls seasonal ailments, especially of children, to diarrhea. The incubation, on the other hand, according to an American study, could develop in about 72 hours. INCUBATION The most recent elements are related to the duration of incubation and are contained in a study published in the United States by the Centers for Disease Control and Prevention (CDC). It may take only 3 days for people to show signs of infection, become contagious, and test positive, according to the median incubation period observed in a cluster of a family of 6. About 72 hours elapsed between the first possible exposure of Case 1 – an unvaccinated 48-year-old man returning from a conference in Nigeria – to the onset of symptoms.
Considering that the median incubation period of the parent coronavirus has been described as being equal to or greater than 5 days and is closer to 4 days for the Delta variant, Omicron times therefore appear to be accelerated compared to the other mutations. The investigation conducted by the authors of the scientific work in question highlighted, among other things, a patient who was reinfected even after complete vaccination, 4 patients who were reinfected and one at the first infection. evidenced a similar or milder clinical syndrome than that associated with previous variants. The data and observation of patients, practically all over the world, have made it possible to progressively deepen and enrich knowledge. The first indications came from South Africa and more massively from Great Britain. The most common symptoms reported and archived by the ZOE COVID app, which has turned into a valuable archive across the Channel, were runny nose, headache, fatigue with muscle aches, sneezing and sore throat. Cases of nausea and diarrhea are reported. Compared to the ‘traditional’ version of the covid, associated in particular to the Delta variant, there are less frequent reports of loss of smell and taste, ‘spy’ symptoms of the disease in previous waves. The milder symptoms risk being confused with cold syndromes , therefore, very common in the winter months and very popular among children. Recovery from common colds occurs within 10 days, according to the Centers for Disease control in the United States. Immunosuppressed people or people with asthma and respiratory diseases, however, risk developing more serious diseases, such as pneumonia.
