Conditions with Flu-like Symptoms

The flu is a fairly common condition, and typical symptoms range from a runny nose and body aches to high fevers and coughs. Fatigue and feeling exhausted throughout the day are also common symptoms. But did you know often these typical flu-symptoms are part of another illness that we mistake as flu? Let’s look at some such conditions below that mimic the flu so correctly we can differentiate them. Visit AFC Urgent Care Vernon if you or a loved one are experiencing any of these symptoms. 

Conditions and Their Symptoms


We previously called it blood poisoning, a condition where the body overreacts to an infection. A human body has to fight infections naturally, but sometimes, something can go wrong inside, and one’s body may begin attacking itself. This is sepsis for you, and it can be fatal if you miss the signs and call it the flu.

This condition’s symptoms include fever (it could be lower than your average body temperature, too), extreme pain, feeling sick, grogginess, or confusion.


Call it inflammation of your meninges or a severe infection, meningitis can mimic the flu-like a pro. You may suffer awful headaches or sudden high fevers, but it is better to seek medical help in the case. Other symptoms include neck stiffness, seizures, vomiting and nausea, light sensitivity in the eyes, skin rash, balancing or walking with difficulty, etc. Meningitis can be avoided by getting the vaccine.


Pneumonia can occur due to a fungal, viral, or bacterial infection, but it resembles flu, at least initially. The most common symptoms are a productive cough, chest pain, fever, chills, bringing up yellow/green sputum, loss of appetite, and breath shortness. Grogginess or confusion may also occur. The best way to identify it as pneumonia is to observe if your sputum color changes, your fever increases persistently or doesn’t go away, and you have chest pain.

Lyme Disease

This is a more prevalent condition in the U.S. It occurs due to a bite from an infected tick bite but produces flu-like symptoms. In this condition, symptoms include swollen lymph glands, fever, body ache, fatigue, chills, and fever commonly occur. The bite may be invisible at times, but others may cause a red rash on your skin, which is the best sign of Lyme disease.

Blood Cancer

In the very early stages of blood cancer, one can experience flu-like symptoms such as fatigue, loss of appetite, persistent cough, sweating, and chills, especially at night. If these symptoms persist for a while, you must see a doctor immediately for the correct diagnosis in time. Other symptoms may include recurring nosebleeds, bone pain, sudden weight loss, etc.
