Catching the Flu in Summer: Symptoms, Causes, and Remedies

Catching the Flu in Summer: Symptoms, Causes, and Remedies | UPMC Italy

Compared to the winter months, catching the flu or a cold is less common during the summer, but it happens more often than one might think. Summer symptoms often feel more bothersome, precisely because of the high temperatures.

Let’s explore the causes of flu-like illnesses in the summer and how to effectively manage them.

Can You Catch the Flu During the Summer?

Although flu outbreaks typically occur in winter, it’s also possible to develop flu-like symptoms in the spring and summer. Several factors can contribute: 

  • Summer viruses with flu-like symptoms may be circulating.
  • Illnesses transmitted by ticks or mosquitoes (e.g., West Nile virus, Lyme disease).
  • Sudden temperature changes caused by air conditioning or shifting weather conditions.
  • A weakened immune system due to stress or fatigue.

What Are the Symptoms of Summer Flu?

The symptoms of summer flu and colds are similar to those experienced in winter and may include:

  • Chills and fever.
  • Muscle and joint pain.
  • Sore throat and cough.
  • Headache.
  • Nasal congestion or runny nose.
  • Fatigue.
  • Diarrhea or vomiting (more common in children).

It’s important to distinguish these symptoms from heatstroke or excessive sun exposure and to consult a doctor for an accurate diagnosis.

Which Viruses Cause Flu-Like Symptoms in Summer?

Several viruses can lead to flu-like symptoms during the summer:

Enteroviruses

Enteroviruses are among the main culprits behind the so-called “summer cold.” They can cause nasal discharge, cough, and in children, fever and muscle aches.

Adenoviruses

Adenoviruses, active year-round, cause cough, sore throat, fever, bronchitis, conjunctivitis, and gastrointestinal issues.

COVID

COVID-19 can also cause flu-like symptoms during the summer. Distinctive features include the gradual onset of symptoms and the potential loss of taste and smell.

Non-respiratory viruses

Viruses like West Nile (transmitted by mosquitoes) or Lyme disease (transmitted by ticks) can cause fever, muscle or joint pain, headache, and sometimes skin rashes. In these cases, typical respiratory symptoms are absent, but it’s essential to consult a doctor for testing and treatment if a rash appears.

When Should You See a Doctor?

 For most mild summer flu symptoms, it’s usually enough to:

  • Rest.
  • Stay well hydrated.
  • Use over-the-counter medications (pain relievers, decongestants, throat lozenges).

However, it’s advisable to see a doctor if:

  • You’re elderly, immunocompromised, or experiencing severe symptoms.
  • Symptoms persist for more than ten days.
  • High fever (> 39.5 °C), dizziness, difficulty breathing, dehydration, severe vomiting or diarrhea, chest pain, mental confusion, or rashes develop.

Seek prompt medical attention in the following cases:

  • Symptoms return after apparent recovery (possible pneumonia).
  • Fever accompanied by a skin rash.
