Covid cases are on the rise again this summer, according to researchers who have seen an uptick in infections every year since the pandemic began. The Centers for Disease Control and Prevention’s forecasting model predicts that infections will grow or likely grow in most states.
High concentrations of Covid in wastewater have been reported in some states, including Texas, Utah, and Nevada. Emergency department visits linked to Covid are also increasing. Researchers attribute this trend to various factors, including warmer temperatures driving people indoors, poor ventilation, and the spread of the virus in crowded areas.
The current wave appears milder than previous ones, with a specific variant, NB.1.8.1., accounting for around 43% of cases. However, it has some additional mutations that may make it more transmissible and evasive to the immune system’s defenses. Experts warn that while the numbers are not yet in a full-blown surge, there is still an upswing.
The spread of Covid during the summer months can be attributed to several factors, including:
– People spending time in air-conditioned spaces with poor ventilation
– Summer travel and crowds fueling the spread
– Immunity waning by summer
Experts emphasize the importance of getting vaccinated and testing if symptoms persist. However, the availability of updated Covid vaccines is uncertain this year.
While the situation does not warrant a panic response, being aware of the rising numbers is crucial for individuals to take necessary precautions.
