Unveiling the Early Signs of the Omicron Variant
Explore the latest insights into the Omicron COVID-19 variant, its rapid spread, early symptoms, and expert advice on protection and prevention.
Healthcare professionals worldwide continue to study the rapidly spreading Omicron variant of COVID-19, which has now been identified in over 110 countries.
Omicron spreads at a significantly faster rate than previous variants, yet its symptoms are generally mild, often resembling a common cold rather than a severe infection. Most infected individuals recover within a few days. This observation is based on data primarily from children and young adults under 39 years old.
One of the earliest indicators of Omicron infection is hoarseness and a scratchy throat, differing from the Delta variant which often caused severe throat pain. Patients frequently notice changes in their voice tone before experiencing fever or general malaise. Additional subtle symptoms include nasal congestion, dry cough, and discomfort in the lower back area, which some women may mistake for premenstrual cramps.
Even fully vaccinated individuals and those recently recovered from COVID-19 remain at risk of contracting Omicron. However, vaccinated persons tend to experience milder and shorter illness duration compared to unvaccinated individuals.

Interestingly, many virologists view Omicron as a potential turning point, as it appears designed to infect a large number of people while causing less severe clinical outcomes. This could eventually lead to COVID-19 becoming a seasonal illness. Widespread lockdowns are not currently recommended; instead, maintaining standard preventive measures remains the most effective defense.
"Closing borders when the virus has already spread across four, possibly all five continents, is illogical. Restricting access to countries monitoring the variant hinders our understanding of its spread and delays crucial information. Border closures have also limited access to testing reagents in African nations, impeding scientific tracking. From an epidemiological perspective, once a virus is widespread, border closures serve no purpose and only contribute to stigmatization," explained virologist Asel Musabekova in an interview with Vlast portal.
She also recommends avoiding large holiday gatherings and corporate events, suggesting that people spend the season at home or outdoors to reduce transmission risk.
The national health authority reports that the incubation period for Omicron ranges from three to six days, with symptoms potentially appearing just hours after exposure. Laboratories are actively developing specialized tests to detect this African-origin variant.
"Using these test systems, we can simultaneously determine if a person is infected with COVID-19 and whether the infection is caused by the Omicron variant," said Rinat Maksyutov, director of the Vector Scientific Center, in an interview with Rossiyskaya Gazeta.
