9 Summer Illnesses to Consider, Other Than COVID-19, When Your Kid Feels Sick

Earlier in the pandemic, I read a story about a family of three who struggled to get COVID-19 tests. Each presented a slightly different set of suspicious symptoms: the son was pale, sweaty, achy, and clearly ill; the mother had a tickle in her throat and a persistent headache; the father, a lingering cough. Turns out, the sickest one — the son — didn’t test positive for COVID-19. Instead, he had a pretty straightforward case of hand, foot, and mouth disease. But in the time of coronavirus, every cough and fever is suspect.

“[I]n this epidemic, with a bug we still know so little about and one that is moving so quickly, everything can look, at least at first, a lot like COVID-19,” Lisa Sanders, M.D., wrote in her New York Times column, Diagnosis, about the family.

Part of the confusion is the generalized paranoia, especially where coronavirus cases are surging. But also, the symptoms of COVID-19 are all over the place. We expect the fever, aches, dry cough, shortness of breath, and the signature loss of smell. But some people have diarrhea and vomiting. Some — kids especially — get swollen, itchy, purple feet, known as COVID toes, or red eyes (like conjunctivitis). And then there’s the most confounding thing about COVID-19 — hardly any symptoms at all.

Once kids start to reenter society — going to the beach, playing outside with a friend or two, or, you know, going to Walt Disney World now that it’s open — they are bound to catch something. Any and all symptoms should be discussed with a health care provider, and should be weighed against the risks you’ve taken, but as your mind goes straight to COVID-19, it helps to remember all the other viruses, bugs, and germs that are also out and about this time of year.

Hand, foot, and mouth disease

As the 20-year-old college student in the New York Times story discovered, hand, foot, and mouth disease is a common summertime virus — one caused by a strain of Coxsackievirus. Most of the time, it affects kids under 5 years old and only rarely younger adults. Symptoms include fever, aches, and pain, which give way to a telltale red rash on the palms, soles of the feet, and in the mouth.

Enterovirus

Coxsackieviruses are just one type of enterovirus, which are quite common. Other non-polio enteroviruses can cause what’s known generally as the “summer flu” or "summer cold" because of the symptoms — fever, coughing, trouble breathing, nausea, and vomiting. Like many viruses, the symptoms can be quite mild, and there’s no treatment other than rest and fluids.

Human parainfluenza virus (HPIV)

There are four types of HPIV, most of which peak in spring and early summer. Like other respiratory viruses, infections are typically mild and include cold-like symptoms.

Adenovirus

Adenoviruses can cause an array of cold-like symptoms, including fever, sore throat, bronchitis, and pneumonia but also diarrhea, and even pink eye (conjunctivitis). And while adenovirus infections occur year-round, in kids and adults alike, it’s slightly more common in spring and early summer.

Strep throat

The streptococcus bacterium that causes strep throat — with top symptoms being fever and sore throat — doesn’t care what month it is.

West Nile virus

In just about every corner of the U.S., summer equals mosquitoes and mosquito-borne illnesses. One in particular, the West Nile virus, can cause mild flu symptoms.

Lyme disease

As ticks spread across the nation, Lyme disease is of increasing concern. It’s possible to not notice the initial tick bite that causes the disease, so the ensuing flu-like symptoms, pain, and fatigue can be perplexing.

Heatstroke

Heatstroke, or sunstroke, can sometimes sneak up on you on a hot summer day. Symptoms include nausea, headache, confusion, rapid breathing and — notably — no sweating.

Food poisoning

Foodborne illness peaks when it’s hot. Symptoms would be obvious other times of the year — vomiting, abdominal pain, diarrhea, a fever, and headaches — but in the time of coronavirus, it can be confusing.
