It’s a common misconception that the flu is only a winter ailment, but experiencing flu-like symptoms in the summer is not unusual. There are several reasons why you might feel under the weather during the warmer months.
Summer Flu & Similar Illnesses
While true influenza is less common in summer, other viral infections can cause similar symptoms. Enteroviruses, including coxsackievirus and rhinovirus, are prevalent in the summer and can lead to symptoms like fever, sore throat, and body aches. Additionally, bacterial infections such as strep throat and bronchitis can occur year-round.
Insect-Bourne Illnesses
Insects are more active during summer, and bites from mosquitoes and ticks can transmit illnesses that mimic flu symptoms. Diseases like Lyme disease, West Nile virus, and Rocky Mountain spotted fever often present with fever, headaches, and muscle aches.
COVID-19 & Other Respiratory Viruses
Even in summer, COVID-19 remains a possibility, as it continues to circulate globally. Other respiratory viruses, like RSV and human metapneumovirus, are also active and can cause flu-like symptoms year-round.
Allergies
Seasonal allergies can sometimes be mistaken for a summer cold or flu. Allergies can lead to congestion, coughing, and fatigue, which are similar to viral infection symptoms. However, allergies typically do not cause fever or significant body aches.
Travel-Related Illnesses
Traveling, especially internationally, can expose you to various pathogens uncommon in your home area. Malaria, chikungunya, and other travel-related illnesses often cause flu-like symptoms and should be considered if you’ve recently been abroad.
What To Do If You Have Symptoms
If you experience flu-like symptoms in the summer, it’s important to consider all possibilities. Contact your healthcare provider, especially if you have severe symptoms or if you’re at higher risk of complications due to age, chronic illness, or a weakened immune system. Early diagnosis and treatment can help manage symptoms and prevent more serious health issues.
Maintaining good hygiene, staying hydrated, and getting plenty of rest can help manage symptoms and support recovery. If you suspect an insect-borne illness or a travel-related infection, inform your doctor about recent travels and insect exposure.
By understanding the various causes of summer flu symptoms, you can take appropriate steps to care for yourself and seek medical advice when necessary. Stay informed and proactive to ensure a healthy and enjoyable summer season.
