COVID-19, Flu, and RSV Cases Spike Amid Summer Heat
2 Aug
Summary
- COVID-19 cases trending up in many states
- Flu and RSV cases currently low, but COVID-19 surging
- Experts warn of late summer virus surge, like past years
As of August 2nd, 2025, the United States is experiencing an unexpected surge in COVID-19 cases, even as the summer heat continues. Federal data shows that while flu and respiratory syncytial virus (RSV) cases remain low, COVID-19 is trending upwards in many mid-Atlantic, southeast, southern, and West Coast states.
This runs counter to the typical seasonal pattern, where respiratory viruses tend to be less active during the warmer months. However, experts say that the past few years have seen late summer surges in COVID-19 cases, and they expect the virus to eventually settle into a winter seasonal pattern like other coronaviruses.
The increase in COVID-19 cases is particularly notable among younger children, with emergency department visits rising for those under 4 years old. This is likely due to many young kids either getting the virus for the first time or remaining unvaccinated.
While the overall number of people seeking medical care for COVID-19, flu, and RSV is currently low, health officials are urging vigilance. The same preventive measures that help stop the spread of colds and flu year-round, such as handwashing, masking, and staying home when sick, can also reduce the risk of contracting these summer viruses.
