The origin of the Omicron variant
Since its meteoric rise in France and in Europe, the Omicron variant has become more and more apparent to experts. While the first symptoms attributed to it were more or less similar to those of the previous variants, a sign, until then relatively unusual, has just been discovered by researchers: night sweats.
“We have seen a sharp increase in cases over the past 10 days. Until now, these were mainly very mild cases, with patients presenting symptoms similar to those of the flu:
– dry cough, fever, night sweats, numerous body aches,“ explained general practitioner Unben Pillay at a conference organized by the South African Department of Health.
Although this new symptom attributed to the Omicron variant has already been observed in Delta variant infections, it has only been observed on very rare occasions. Medically, night sweats are described as “repeated episodes of extreme sweating”, which occur during the sleep phase. In other words, the person concerned may wake up drenched in sweat.
In addition to this possible manifestation of Covid-19 infection, which seems to be more specific to Omicron, four other symptoms have been described by scientists: itchy throat, skin rashes (especially in children), muscle pain and extreme fatigue.
According to a report published by the U.S. Centers for Disease Control and Prevention, “cough, fatigue, congestion or runny nose” are the most frequently reported symptoms, similar to those of the common cold. Fever, nausea, vomiting, shortness of breath and diarrhea were also reported, but to a lesser extent.
