A highly infectious variant carries significant risk for unvaccinated or partially vaccinated communities, as it can increase hospitalizations and overall strain on health-care facilities. Its emergence led dozens of countries to reinstate restrictions on foreign travel, largely from southern Africa, and prompted calls to ramp up global vaccinations. Scientists flagged omicron due to its high number of mutations, which could affect factors such as how easily it spreads and the severity of illness it causes, though researchers are in the early stages of studying its behavior.
