Summer usually brings warmth, outdoor activities, and, well, the unexpected arrival of cold and flu symptoms.
Many people might not connect the dots here, largely due to common misconceptions about germs and the reality that viruses tend to be less active during warmer months.
However, it is still possible to catch a cold—or something worse—during summer. Recent data from federal sources indicates a rise in COVID-19 cases in various regions, accompanied by an increase in emergency department visits across all age groups.
Here’s what you should know about summer viruses.
What’s the status of colds and flu right now?
Currently, the number of people seeking medical attention for COVID-19, influenza, and respiratory syncytial virus (RSV) is low, according to the Centers for Disease Control and Prevention.
Cases of flu are decreasing, and RSV has remained stable this week. Nevertheless, COVID-19 is showing an upward trend in several states along the mid-Atlantic, Southeast, Southern, and West Coast.
Experts believe COVID-19 may eventually follow a seasonal pattern like other coronaviruses, but the last few years have seen late summer spikes, noted Dr. Dean Blumberg from the University of California Davis Children’s Hospital.
Other viruses making the rounds this time of year include the one that causes “hand, foot, and mouth” disease, which shares symptoms with colds but also includes sores and rashes—additionally, norovirus, sometimes referred to as stomach flu.
Do viruses really spread less during the summer?
Many viruses show seasonal patterns, typically increasing as fall and winter temperatures drop. So yes, fewer people report colds in the summer, but it’s important to note that cold weather itself doesn’t cause them.
Behavior plays a significant role too, according to experts. People tend to open windows and spend more time outdoors when the weather is pleasant, making it harder for germs to spread.
Yet, respiratory viruses continue to exist. When temperatures rise and everyone seeks refuge indoors with air conditioning, doctors often see a spike in illnesses. In extremely hot regions, summer can feel like its own cold season.
“I grew up on the East Coast, and it’s no secret that everyone falls sick in the winter,” Dr. Frank LoVecchio, an emergency room physician and researcher at Arizona State University, mentioned. “However, summer illnesses are common here. The reason? People are indoors more.”
Should you get another COVID-19 booster now?
For healthy individuals, timing can be crucial for vaccinations. If you’re considering getting boosted, it’s best to do it a few weeks before a significant event like a wedding or a trip. However, most might want to wait until fall, anticipating an uptick in winter COVID-19 cases.
“You want to ensure you’re fully protected when it matters most,” explained Dr. Costi Sifri from the University of Virginia Health System.
Those at a higher risk for complications should definitely consult their doctor for tailored advice. Older adults and individuals with weak immune systems may require more frequent boosters.
Are younger kids getting sicker with COVID-19?
Recent reports from the CDC highlight an uptick in emergency room visits for children under 4. This is understandable, Dr. Blumberg noted, as many young kids are either unvaccinated or encountering COVID-19 for the first time.
Health Secretary Robert F. Kennedy Jr. stated that in May, COVID-19 vaccinations would no longer be recommended for healthy children—a decision that has faced criticism from health experts regarding its scientific backing. The American Academy of Pediatrics still supports COVID-19 vaccines for children over six months old.
How else can I reduce my risk?
The preventive measures that work against colds, flu, and COVID-19 throughout the year remain effective in summer, according to medical professionals.
Whenever possible, spend time outside, wash your hands frequently, and consider wearing a mask. If you’re unwell, it’s best to stay home.
