COVID-19 variant XEC prompts concerns as infections rise in Finland

The coronavirus continues to circulate within the population, causing periodic spikes in infections. Eeva Ruotsalainen, a physician and infection disease specialist at HUS, noted that last year saw three waves of epidemics, with the most severe occurring from October to December. Unlike influenza and the RS virus, which show clear seasonal patterns, the coronavirus has not followed a predictable trend.

Ruotsalainen reported that this year’s COVID-19 wave began in late summer, with a milder wave extending into September affecting both healthy individuals and those in high-risk groups. A new variant, the XEC, which has spread across Europe since summer, is expected to prompt another wave in Finland. This variant is notably more contagious than previous strains.

For older adults, the risk of hospitalization from complications due to COVID-19 remains high. The virus has been linked to a significant increase in mortality rates among the elderly. COVID-19 vaccinations continue to be a critical measure to protect individuals over 65 and others in high-risk categories. Last year, vaccination efforts lagged behind, resulting in more than double the number of deaths from COVID-19 compared to the first year of the pandemic.

This year’s vaccination schedule was expedited, yet only 54% of those over 80 and 23% of individuals aged 65-79 have been vaccinated nationwide. Ruotsalainen emphasizes that 80% coverage is necessary in the over 65 group to reduce hospitalizations and deaths.

Both COVID-19 and influenza vaccines should be administered ahead of the autumn and winter epidemic waves. Free influenza vaccines are available not only to at-risk groups but also to their close contacts. It is crucial to recognize that COVID-19 presents more severe symptoms than typical flu viruses, making early vaccination essential for protection.
