The COVID-19 pandemic continues to evolve, with two new variants—EG.5 and HV.1—now accounting for nearly half of all infections in the United States. These variants are a stark reminder that the virus is still a significant public health concern, even as much of the world returns to normalcy.
What Are EG.5 and HV.1?
EG.5 and HV.1 are closely related variants of SARS-CoV-2, the virus that causes COVID-19. Both strains have mutations that make them more transmissible than earlier variants. However, there is no evidence to suggest they cause more severe illness.
The rapid spread of these variants is concerning because it demonstrates the virus’s ability to adapt and potentially evade immunity. While existing vaccines still provide strong protection against severe disease and hospitalization, experts emphasize the importance of staying up to date with booster shots to maintain immunity.
Public Health Recommendations
Health officials are urging people to take preventive measures to reduce the spread of these variants, particularly as the winter months approach. These include:
- Vaccination and Boosters: Staying current with vaccinations is the best defense against severe illness.
- Testing: Regular testing remains an essential tool, especially for those experiencing symptoms or who have been in close contact with infected individuals.
- Masking: Wearing masks in crowded or poorly ventilated indoor spaces can help reduce transmission.
Why Vigilance Is Still Necessary
While the severity of illness caused by EG.5 and HV.1 remains comparable to previous strains, the increased transmissibility of these variants underscores the need for continued vigilance. The holiday season, with its indoor gatherings and travel, presents an ideal environment for the virus to spread.
This serves as a reminder that COVID-19 is not over. By following public health guidance and remaining proactive, the U.S. can manage the impact of these variants and protect vulnerable populations.
