Preventing Long Covid
The best way to prevent Long Covid is to avoid getting COVID-19.
Key Prevention Strategies
Wear a High-Quality Mask
Wearing a well-fitted, high-filtration mask (like an N95, KN95, or KF94) in indoor public spaces or crowded areas is one of the most effective ways to reduce your risk of inhaling viral particles.
Stay Up-to-Date on Vaccinations
While vaccination may not always prevent infection entirely, studies show it significantly reduces the risk of developing Long Covid. Staying current with recommended boosters helps your body maintain a strong defense.
Improve Ventilation & Practice Distancing
COVID-19 spreads through the air. Improving ventilation by opening windows, using air purifiers with HEPA filters, or meeting outdoors can disperse viral particles. Maintaining distance from others when possible also reduces exposure.
The Challenge of Tracking Covid
In the United States and many other countries, official government tracking of daily COVID-19 cases has largely ceased. This means there is no longer a reliable, centralized source to know the true prevalence of the virus in our communities.
The widespread use of at-home tests, which are rarely reported, further complicates the data. As a result, we now rely on other indicators like wastewater surveillance, emergency room visits, and hospitalization rates to estimate viral activity. While these methods are helpful, they don't provide a complete picture, making personal risk assessment more important than ever.
Global Reported COVID-19 Cases (28-Day Periods)
This chart shows the number of new cases officially reported to the World Health Organization (WHO) in 28-day periods. It illustrates the global trends and waves of the pandemic. Please note: due to limited testing and reporting worldwide, the true number of infections is significantly higher than what is shown here.
