Recurrent Infections: Why Some People Fall Sick Again & Again?
Do you or your family members fall sick very often?
Do infections like fever, cold, stomach problems, or skin infections keep coming back again and again?
These are called recurrent infections. Many people ignore them as “seasonal illness” or “weak immunity, but in reality, repeated infections can be a warning sign of an underlying health problem.
In this blog, Dr A. Murali, an experienced Infectious Disease Specialist in Coimbatore, explains why recurrent infections occur, when to be concerned, and how they can be effectively treated.
What Are Recurrent Infections?
Recurrent infections are illnesses that occur frequently, return soon after treatment, or do not completely resolve.
They may affect the same organ (like lungs or stomach) or different parts of the body repeatedly.
If infections keep returning, it means the body’s defence system is not working properly, or the root cause is untreated.
Common Signs of Recurrent Infections:
You may be experiencing recurrent infections if you have:
- Fever that comes back frequently
- Repeated cough, cold, or chest infections
- Frequent diarrhoea or stomach infections
- Recurrent urinary tract infections (UTI)
- Repeated skin boils, abscesses, or fungal infections
- Slow recovery even after medicines
- Feeling tired or weak all the time
If these symptoms occur more than three to four times a year, a medical evaluation is recommended.
Why Do Some People Fall Sick Again and Again?
1. Weak Immune System:
The immune system protects the body from infections. When it is weak, infections occur easily and repeatedly.
Common causes of weak immunity include:
- Poor nutrition
- Lack of sleep
- Chronic stress
- Vitamin deficiencies
- Ageing
- Long-term illnesses
2. Diabetes and Other Chronic Diseases:
People with diabetes often suffer from:
- Recurrent UTIs
- Skin infections
- Chest infections
High sugar levels reduce the body’s ability to fight infections. Other conditions like kidney disease, liver disease, and lung disease also increase infection risk.
3. HIV and Immune Disorders:
Undiagnosed HIV infection or immune system disorders can cause:
- Repeated fever
- Tuberculosis
- Fungal infections
- Persistent diarrhoea
Early diagnosis and treatment can significantly improve quality of life, which is why specialist evaluation is crucial.
4. Incomplete or Wrong Treatment:
Stopping antibiotics early or taking medicines without a proper diagnosis can lead to:
- Partial cure
- Drug resistance
- Infection returning stronger than before
This is a very common cause of recurrent infections in India.
5. Post-COVID or Post-Viral Weakness:
Many people experience reduced immunity after:
- COVID-19
- Dengue
- Viral fever
- Chikungunya
This temporary weakness can cause repeated infections if not managed properly.
6. Recurrent Exposure to Infection Sources:
Some people get exposed repeatedly due to:
- Poor hygiene
- Contaminated food or water
- Crowded workplaces
- Travel-related infections

When Are Recurrent Infections Serious?
Recurrent infections are serious if:
- Fever lasts more than 7 days repeatedly
- Infections do not respond to usual medicines
- Weight loss or night sweats are present
- Infections involve multiple organs
- Hospitalisation is needed frequently
In such cases, consulting an Infectious Disease Specialist is strongly recommended.
