E. coli, short for Escherichia coli, is a bacterial group commonly found in our intestines and in some animals. While many E. coli strains are harmless and even beneficial, certain types can cause serious infections. Knowing the symptoms of an E. coli infection and when to seek a diagnosis can help prevent complications, especially if you catch the infection early. Here, we’ll dive into the early signs of E. coli infection, ways to test for it, and how Second Medic offers top-quality E. coli diagnostic services to help you stay healthy.

Understanding E. coli: What is it?

Escherichia coli is naturally present in human and animal intestines, and it plays a vital role in digestion. However, some strains, like E. coli O157 produce toxins that cause infections and lead to symptoms ranging from mild discomfort to severe gastrointestinal issues. E. coli infections often result from consuming contaminated food or water or through direct contact with animals or people carrying the bacteria.

Early Symptoms of E. coli Infection: What to Watch For

The initial signs of an E. coli infection can appear within 1 to 10 days after exposure, with most cases surfacing around 3 to 4 days post-infection. Recognizing these early symptoms of E. coli is essential, as timely intervention can prevent escalation.

Common Early Symptoms of E. coli Infection:

  1. Abdominal cramps: One of the first signs is intense stomach cramping. Unlike regular stomach pain, the cramps associated with an E. coli infection are usually sharp and persistent.

  2. Diarrhoea: Initially, diarrhoea may be mild, but it can quickly become severe and even bloody as the infection progresses. In many cases, E. coli can cause bloody diarrhoea, indicating a more severe strain.

  3. Nausea and vomiting: Nausea is common, with some individuals experiencing vomiting due to the bacterial toxins irritating the digestive system.

  4. Fatigue: Constant discomfort from symptoms like stomach cramps, diarrhoea, and nausea can lead to fatigue and weakness.

  5. Loss of appetite: Many people with an E. coli infection report a decreased desire to eat, which can contribute to further weakness.

If these symptoms sound familiar or have been persistent, especially if you suspect exposure to contaminated food or water, it’s crucial to consider E. coli testing. Early detection through accurate diagnosis is vital to prevent severe complications.

Signs of E. coli Infection in Adults

Symptoms of E. coli infection in adults are similar to those in children but can sometimes go unnoticed or be mistaken for other gastrointestinal issues. Adults may not realize the severity of the infection until it worsens, so being aware of E. coli infection symptoms can help prevent unnecessary suffering. Key signs to watch for include:

  • Persistent abdominal cramps and pain: E. coli stomach pain symptoms tend to be sharp and do not ease with time, unlike common stomachaches.

  • Bloody diarrhoea: As mentioned, bloody stools are a red flag that you might be dealing with a severe strain of E. coli.

  • Increased dehydration: Persistent diarrhoea can lead to dehydration, marked by dry mouth, dizziness, and reduced urine output.

  • High fever: Although less common, fever can occur in some cases and may signal the body’s response to infection.

When to Get Tested for E. coli

So, when should you seek professional help? If you’re experiencing persistent symptoms or if you suspect recent exposure to contaminated food or water, it’s best to get tested. Testing is particularly important if:

  • Symptoms persist beyond a few days

  • You notice blood in your stool

  • You experience severe abdominal cramps and dehydration

  • Someone in your household has recently been diagnosed with an E. coli infection

Ignoring these symptoms or delaying diagnosis can lead to severe complications, such as hemolytic uremic syndrome (HUS), which affects kidney function. Early testing is the best way to prevent the infection from worsening.

Can E. coli Cause Bloody Diarrhea?

Yes, E. coli can cause bloody diarrhoea, especially in cases involving more severe strains. The Shiga toxin-producing E. coli (STEC) is particularly dangerous and often results in bloody stools, severe abdominal cramps, and vomiting. If you observe bloody diarrhoea, it’s essential to seek immediate medical help. Blood in the stool can indicate a severe infection that might require urgent intervention.

Prevention Tips: How to Avoid an E. coli Infection

Prevention is always better than cure, and there are several ways to reduce your risk of contracting E. coli:

  • Practice proper food hygiene: Ensure all foods, especially meats, are thoroughly cooked, and avoid consuming unpasteurized dairy products.

  • Wash hands regularly: Wash your hands after handling raw meat, using the restroom, and interacting with animals.

  • Avoid cross-contamination: Use separate cutting boards for raw meats and vegetables, and always clean surfaces after food prep.

  • Be cautious with water sources: Drink treated water, especially when travelling, and avoid swallowing water from lakes, pools, or untreated sources.

Symptoms of E. coli Infection You Shouldn’t Ignore

To recap, E. coli infection symptoms can range from mild to severe and may progress quickly if untreated. Watch out for early symptoms of E. coli such as intense abdominal cramps, bloody diarrhoea, nausea, and vomiting. These symptoms are more than discomfort; they can signal a serious infection requiring prompt attention.

Human Metapneumovirus (HMPV)

Human Metapneumovirus (HMPV): Treatment & Symptoms

Human Metapneumovirus (HMPV) is a respiratory virus that causes illness in people of all ages, particularly young children, older adults, and people with weakened immune systems. The virus can lead to conditions such as bronchitis, pneumonia, and upper respiratory infections. With rising cases globally and in India, awareness about HMPV, its symptoms, and available treatment options is essential.

In this blog, we'll break down everything you need to know about Human Metapneumovirus (HMPV): Treatment & Symptoms in easy-to-understand language.

 

What is Human Metapneumovirus (HMPV)?

HMPV is a virus that belongs to the Paramyxoviridae family—the same group of viruses responsible for illnesses like RSV (Respiratory Syncytial Virus) and mumps. It was first discovered in 2001 but is now known to have been circulating for decades.

The virus mainly affects the respiratory tract and can range from mild cold-like symptoms to severe lower respiratory infections. It spreads most commonly in late winter and spring, similar to flu season.

 

HMPV in India: Current Overview

In 2025, several hospitals in India have seen a rise in cases of HMPV among children and elderly patients. Though not as widely known as COVID-19 or flu, Human Metapneumovirus is a common cause of pediatric hospital admissions during respiratory infection surges.

Doctors advise taking it seriously because it can mimic flu or pneumonia, making early diagnosis crucial.

 

Common Symptoms of HMPV

The symptoms of HMPV are similar to other respiratory viruses. They can range from mild cold-like symptoms to severe breathing difficulties, especially in vulnerable groups.

Main Symptoms Include:

  • Fever

  • Cough

  • Runny nose

  • Nasal congestion

  • Sore throat

  • Wheezing

  • Shortness of breath

  • Fatigue

  • Loss of appetite (especially in children)
     

In severe cases, it can lead to bronchitis or pneumonia.

 

How is HMPV Transmitted?

Human Metapneumovirus spreads from person to person through:

  • Coughing and sneezing

  • Close personal contact

  • Touching contaminated surfaces or hands
     

The virus can survive on surfaces like toys, doorknobs, and tables for several hours. That’s why regular handwashing and hygiene are essential.

 

How is HMPV Diagnosed?

Since HMPV symptoms resemble other viral infections, a lab test is the only way to confirm the virus.

Tests may include:

  • RT-PCR (Reverse Transcriptase Polymerase Chain Reaction) for detecting viral RNA

  • Nasopharyngeal swabs

  • Rapid antigen tests (less common)
     

In India, you can book respiratory virus panels or flu-like illness tests from diagnostic labs like Thyrocare through SecondMedic to check for multiple viruses including HMPV.

 

Human Metapneumovirus (HMPV): Treatment

There is no specific antiviral drug for HMPV. Treatment is mainly supportive, aimed at relieving symptoms.

Supportive Treatments:

  • Fever reducers like paracetamol

  • Cough suppressants

  • Steam inhalation

  • Hydration (drinking fluids)

  • Rest
     

Hospitalization is required if:

  • Breathing becomes difficult

  • Oxygen levels drop

  • Patient is elderly, a young child, or has chronic illnesses (like asthma or heart disease)
     

Doctors may provide oxygen therapy or nebulizers to ease breathing in severe cases.

 

How to Prevent HMPV

As with many respiratory infections, prevention is the best protection.

Tips to Avoid Infection:

  • Wash your hands regularly with soap and water.

  • Use alcohol-based hand sanitizers when outside.

  • Cover mouth and nose when sneezing or coughing.

  • Avoid touching your face, especially eyes and nose.

  • Disinfect commonly used surfaces at home and work.

  • Avoid close contact with sick individuals.

  • Wear a mask in crowded places during flu season.
     

There is no vaccine for HMPV yet, but researchers are working on developing one.

 

Who is Most at Risk?

  • Infants and toddlers (under 5 years)

  • Adults over 65

  • People with weakened immune systems

  • Individuals with chronic respiratory or heart diseases
     

These groups may experience more severe symptoms and need urgent care if infected.

 

When to See a Doctor

You should consult a doctor if:

  • Symptoms last more than 5–7 days

  • Breathing becomes difficult

  • Fever is very high or persistent

  • There's chest pain or confusion

  • A child has a bluish face or lips
     

Early intervention can prevent complications.

 

Recommended Tests on SecondMedic (Powered by Thyrocare)

While there is no HMPV-specific test for home collection, you can book tests like:

  1. Complete Blood Count (CBC)

  2. CRP (C-Reactive Protein)

  3. Respiratory Pathogen Panel

  4. Influenza A & B Detection

  5. RT-PCR Viral Panels (on request)

Conclusion

Human Metapneumovirus (HMPV) is a growing cause of respiratory illness in India, especially in children and the elderly. Though there is no specific cure, early diagnosis and symptom-based treatment can help patients recover fully. Practicing good hygiene and avoiding close contact with sick people are the best ways to prevent infection.
