Covid-19 cases rise again this summer, with wastewater signals strongest in some states
The Centers for Disease Control and Prevention’s forecasting models suggest that infections are growing, or likely to grow, in most states this summer. While national wastewater data show generally low virus levels, several states — including Texas, Utah and Nevada — report very high concentrations of Covid in wastewater, and emergency departments are seeing more visits linked to the illness.
Researchers say an uptick was anticipated, even as the virus continues to surprise with shifting variants and evolving symptoms. Historically, Covid-19 cases have climbed during the summer in many years of the pandemic, though the scale and impact appear to vary from wave to wave.
By contrast to last year, when wastewater levels were higher around this time, the current uptick seems to be milder so far. Nevertheless, public health officials emphasize vigilance, as trends can change quickly with new variants and fluctuating immunity in the population.
What this means for individuals and communities
– Vaccination remains the strongest defense. If you’re eligible for an updated booster, consider getting it to bolster protection against circulating strains.
– Monitor symptoms and test if you develop fever, cough, shortness of breath, or have had a recent exposure.
– In crowded indoor settings or areas with high transmission, masking and good ventilation can help reduce risk, especially for those at higher risk of severe illness.
– Stay tuned to local health department guidance, as recommendations can vary by region and over time.
Summary of outlook
Overall, health officials are watching for a continued summer uptick, but the signals so far point to a milder wave than last year if current trends persist. Continued vaccination, surveillance, and adaptive public health guidance will be key as the season progresses. A hopeful note is that increasing immunity from vaccines and prior infections, along with ongoing monitoring, helps limit severe outcomes even when infections rise.
