HMPV Virus: How Dangerous is it? Understand its Symptoms, Severity, and Treatment

As India grapples with a recent surge in Human Metapneumovirus (HMPV) cases, many are drawing parallels to the COVID-19 pandemic due to similar respiratory symptoms. But what exactly is HMPV, and should we be concerned about it? This comprehensive blog will explain everything you need to know about this respiratory virus, from its severity and transmission to symptoms, diagnosis, and prevention strategies.

 
What is Human Metapneumovirus (HMPV)?

Human metapneumovirus (HMPV) is a respiratory pathogen belonging to the Pneumoviridae family and the Metapneumovirus genus. First discovered in 2001, this single-stranded negative-sense RNA virus has established itself as a significant cause of respiratory infections worldwide. While it may sound complex, HMPV is a common respiratory infection that typically appears during the winter and early spring months.

The virus is prevalent in human populations, with most people experiencing their first HMPV infection during early childhood. While the body develops some immunity after initial exposure, the virus can still cause repeat infections throughout a person's life, though these tend to be milder than the first encounter.

 
Human Metapneumovirus Symptoms

Most HMPV symptoms are mild and resolve within 2-5 days. These include:

 
In severe cases, symptoms may include:

  • Wheezing
  • Asthma flare-ups
  • Difficulty breathing
  • Fatigue
  • Bronchitis
  • Ear Infection
  • Pneumonia
  • Severe bronchiolitis (more common in children)

 
HMPV is responsible for about 10% to 12% of respiratory illnesses in children. While most cases are mild, up to 16% can lead to serious complications, such as pneumonia or lower respiratory tract infections. Babies under 1 may have feeding difficulties. If symptoms last beyond two weeks or worsen, seek medical attention immediately.

 
Who is at Risk?

HMPV poses a higher risk to:

  • Young children: May develop bronchiolitis or pneumonia.
  • Elderly: Especially those 65+ or with asthma, COPD, or chronic illnesses.
  • Pregnant women: Can experience respiratory issues affecting both mother and baby.
  • Immunocompromised individuals: At risk of severe symptoms due to conditions or treatments like chemotherapy.
  • Individuals who have asthma or COPD.

 
Human Metapneumovirus (HMPV) vs. COVID-19

HMPV and COVID-19 are contagious respiratory illnesses with similar symptoms, including runny nose, cough, fever, congestion, sore throat, and shortness of breath. Both can cause severe cases requiring hospitalization. However, unlike COVID-19, HMPV lacks antiviral treatments or vaccines and is seasonal, peaking in winter and spring. Studies show HMPV cases tripled in some countries post-pandemic, as eased COVID-19 measures increased exposure to respiratory illnesses.

 
How is Human Metapneumovirus Spread?

Human metapneumovirus (HMPV) is caused by a virus related to RSV, measles, and mumps, which infects the respiratory system. It spreads primarily through

Close contact with an infected person: Coughing, sneezing, shaking hands, hugging, or kissing.

Contaminated surfaces: Touching objects like toys, phones, or door handles with the virus.

 

Human Metapneumovirus Diagnosis

Healthcare providers typically diagnose HMPV based on your symptoms and medical history. To confirm the infection, they may take a sample from your nose or throat using a soft-tipped swab, which is then tested in a lab for viruses and other infections. Testing for HMPV is generally reserved for those with severe symptoms. In some cases, a bronchoscopy or chest X-ray may be performed to examine the airways and check for lung changes.

 
Treatment of Human Metapneumovirus

There is no specific cure for HMPV, but symptoms can be managed with supportive care. Mild cases often improve on their own. To ease symptoms, you can:

  • Take over-the-counter pain relievers for fever and pain.
  • Use decongestants or corticosteroid sprays for nasal congestion.
  • Use an inhaler for breathing difficulties like wheezing.

Severe cases may require hospitalization for oxygen therapy, IV fluids, or corticosteroids to reduce inflammation. Antibiotics are not effective unless a secondary bacterial infection occurs.

 

Prevention of Human Metapneumovirus

While there’s no vaccine for HMPV, you can reduce the risk of infection by:

  • Washing your hands regularly with soap and water for at least 20 seconds.
  • Avoiding close contact with sick individuals.
  • Covering your mouth and nose when coughing or sneezing, preferably into your elbow.
  • Using alcohol-based sanitizers or wipes after sneezing or touching high-contact surfaces.
  • Try to stay at home when you experience any symptoms.

People with chronic lung conditions like COPD or asthma should take extra precautions and stay up to date on vaccinations to protect against respiratory infections.

 
HMPV Virus in India

Human Metapneumovirus (HMPV) is a globally circulating respiratory virus, including in India. While India recently confirmed two cases at a Bengaluru hospital, the Union Health Ministry emphasized there has been no unusual surge in cases. Experts clarified that HMPV is not new, having been identified in 2001 and likely existing since the 1950s. It primarily causes mild respiratory infections, and most children develop immunity by age 10.

Current data from the Indian Council for Medical Research (ICMR) and the Integrated Disease Surveillance Programme (IDSP) shows no significant rise in Influenza-Like Illness (ILI) or Severe Acute Respiratory Illness (SARI). Hospitals are well-prepared, and health systems remain vigilant. Citizens are advised to take standard precautions, such as wearing masks, washing hands, and consulting a doctor if severe symptoms occur.

Non-alcoholic Fatty Liver Disease: What You Need to Know

The liver plays an essential role in our body. It helps in the detoxification process by filtering out harmful substances from the blood and producing bile to aid in digestion. When the liver is damaged or exposed to toxins, it loses its ability to function normally. In recent times, non-alcoholic fatty liver disease (NAFLD) has emerged as a major health issue, affecting millions of people worldwide. Understanding the risk factors of NAFLD is crucial for effective management. In this blog, you will learn about these risks and find ways to protect your liver health.

Non-Alcoholic Fatty Liver Disease (NAFLD) 

Non-alcoholic fatty Liver Disease (NAFLD) is a condition identified by the buildup of fat in the liver of individuals who consume minimal or no alcohol. If NAFLD is not treated properly for a long period of time it leads to serious liver conditions, such as non-alcoholic steatohepatitis (NASH) and cirrhosis, liver cancer, or liver failure.

Causes of NAFLD

The causes of non alcoholic fatty liver disease is not clear, but the researchers believe the following factors may contribute to its development:

NAFLD Signs and Symptoms

Generally, non alcoholic fatty liver disease is a silent disease with no indications. However, when the disease progresses some individuals may experience symptoms such as:

  • Fatigue
  • Weakness
  • Abdominal discomfort
  • Jaundice

Who is at Risk?

The non-alcoholic fatty liver disease is common in people who are overweight or obese, have type 2 diabetes, or have high cholesterol. It is also more prevalent in older adults and those with a sedentary lifestyle. Additionally, individuals with a family history of liver disease may be at an increased risk for developing NAFLD.

How to Prevent NAFLD

There are several ways to prevent NAFLD and promote liver health. The following strategies can help reduce the risk of developing it:

  • Eat healthy: Include foods that support liver health, such as fruits, vegetables, whole grains, and lean proteins
  • Exercise daily: Aim for at least 25 minutes of exercise a day.
  • Avoid processed foods: Processed foods are high in unhealthy fats, sugars, and additives that can contribute to liver damage.
  • Manage chronic conditions such as diabetes and high cholesterol: These conditions can contribute to liver damage, so it is important to work with your healthcare provider to keep them under control.

How is NAFLD Diagnosed?

NAFLD has no symptoms. Generally, it is identified after the blood test results that higher-than-normal levels of liver enzymes.

Once NAFLD is suspected, the doctor goes for physical examinations like insulin resistance, and cirrhosis. In addition, the healthcare professional may recommend for

  • Ultrasound to understand the fat in the liver
  • Transient elastography to measure the liver stiffness
  • Liver biopsy for accuracy

Treatment Options

Treatment for non-alcoholic fatty liver disease has no specific medications or specific treatments. Studies are currently being conducted to determine whether a specific diabetes medication or Vitamin E can be beneficial; however, further research is needed.

In addition, losing weight is commonly suggested for managing this condition. So, for some individuals weight loss surgery is recommended.

When to Consult a Doctor?

  • It is important to consult a doctor if you are experiencing symptoms such as fatigue, abdominal pain, or yellowing of the skin and eyes.
  • Regular check-ups and monitoring of liver function tests are recommended for those at risk of NAFLD. 


In conclusion, NAFLD is a serious but manageable condition with a significant impact on liver health. By altering the lifestyle and making healthier choices, individuals with NAFLD can improve their liver function and reduce the risk of developing more severe liver diseases such as cirrhosis or liver cancer. If you are at risk of developing inflammation or scarring in your liver, consult with your healthcare provider.

Understanding Mpox: What You Need to Know About the Virus and Its Impact

The world has faced various viral threats over the years and the mpox is the latest to demand urgent action. The disease was initially identified in the Democratic Republic of the Congo in 1970 and is now rapidly spreading to other countries causing widespread concern. This led the World Health Organization (WHO) to declare it as a global health emergency. It is important to control the outbreak before it becomes uncontrollable.

In India, doctors and hospitals have been alerted that immediate reporting of any patient exhibiting Mpox symptoms is mandatory. However, it is essential for every individual to stay informed about the virus, its symptoms, and prevention methods to protect themselves and others from getting infected.  Therefore, this blog will give you a better understanding of Mpox and help you make informed decisions.

What is Mpox?

Mpox, formerly called monkeypox, is a rare disease caused by the Mpox virus. This virus is a member of the Orthopoxvirus genus, which is closely related to the virus responsible for smallpox and there are two types of Mpox virus:

  • Clade I
  • Clade II

How does it spread?

Mpox is a zoonotic disease that has the potential to spread between animals, from animals to humans, and between humans. It primarily spreads in tropical rainforests, where the virus is transmitted by animals like squirrels, Gambian pouched rats, dormice, and various monkey species. The virus is transmitted among humans through close contact with an infected individual or by touching contaminated items such as bedding or clothing. In addition, transmission can occur through handling or consuming the meat of infected animals, particularly in regions where the virus is prevalent.

What are the symptoms of Mpox?

The common symptoms of Mpox are:

How to Prevent Mpox Infections?

To reduce the risk of Mpox infection, follow these guidelines:

  • It is recommended to get vaccinated to prevent Mpox spread. Since no specific Mpox vaccine is available yet, antiviral drugs like tecovirimat or cidofovir are used to manage symptoms.
  • Stay away from animals that are sick, dead, or appear to be affected by Mpox.
  • Keep away from beds and other items that might be contaminated with the virus.
  • Ensure that all animal meat or meat products are cleaned and cooked properly to limit the spread of Mpox virus.
  • Wash your hands frequently.
  • Use condoms to reduce the risk of transmission during sexual activity.
  • Cover your mouth and nose with a mask when around others.
  • When dealing with potential cases of Mpox, wear appropriate Personal Protective Equipment (PPE) to protect yourself.

Following these steps can help reduce the risk of Mpox infection and contribute to public health and safety.

Mpox in India

The ongoing outbreak of Mpox has affected 116 countries and is severe in the Democratic Republic of Congo and neighbouring countries, highlighting the importance of public health measures in preventing the spread of infectious diseases. Pakistan, a neighbouring country to India, has also been impacted by Mpox cases. While the likelihood of the virus spreading from Africa to India remains moderate, it is essential for Indian authorities to stay alert and initiative-taking. Monitoring and implementing strict public health measures can help prevent the spread of Mpox within the country.

Common Diseases in Rainy Season and Preventive Tips

The rainy season, while beautiful and refreshing, brings with it an increased risk of certain diseases. As moisture levels rise and stagnant water accumulates, conditions become ideal for various pathogens and disease-carrying insects to thrive. This blog post aims to inform you about the most common illnesses associated with the monsoon season and provide practical tips to keep you and your family healthy. By understanding these risks and taking simple precautions, you can fully enjoy the rainy months while safeguarding your well-being. Let's explore the common monsoon-related diseases and learn effective prevention strategies.

Dengue

The mosquito-borne tropical sickness caused by the dengue virus can be extremely painful and life-threatening, necessitating hospitalization. Symptoms usually last 2-7 days and include high fever, headache, nausea, vomiting, rash, muscle and joint aches. Most dengue patients recover in roughly a week. If you are experiencing vomiting, dizziness, or difficulty breathing, consult a doctor.

Malaria

Malaria, another mosquito-borne disease, is caused by Plasmodium parasites carried by infected Anopheles mosquitoes. It causes fever, chills, and flu-like symptoms, which can be severe if not treated promptly. Blood tests are used to diagnose malaria, and while it may be treated with antimalarial medications, certain strains become resistant.

Cholera

Cholera is a bacterial infection caused by Vibrio Cholerae that results in severe diarrhoea and dehydration. It spreads by contaminated water and food, which is more likely during the rainy season due to flooding and poor sanitation. If left untreated, cholera can kill a person within hours. Treatment consists of oral rehydration therapy and, in extreme situations, intravenous fluids.

Typhoid

Typhoid, caused by the Salmonella Typhi bacteria, is transmitted by contaminated food and drink. Symptoms include high fever, weakness, stomach ache, and loss of appetite. If not addressed, it can cause prevalent serious consequences. Typhoid is detected with blood, stool, or bone marrow testing and can be treated with antibiotics, though certain strains are becoming resistant.

Cold and Flu

The extreme temperature fluctuations that occur during the rainy season make the body susceptible to bacterial and viral attack, resulting in colds and flu. This is the most prevalent type of viral infection. To safeguard the body, one should eat highlyb nutritious foods to increase immunity. This allows the body to combat pathogens by generating antibodies that are resistant to the toxins that have been released.

 

Prevention Tips

To keep healthy during the rainy season, consider the following general preventive measures:

1. Maintain proper personal hygiene

Wash your hands frequently with soap and water, especially before eating and after going to the 

restroom. Keep your body clean and dry to avoid fungal infections.

2. Ensure water safety

Consume only boiled or cleaned water. Avoid consuming water from unknown sources, particularly during floods or heavy rains.

3.  Food Safety Consume only freshly cooked, hot dishes

Avoid raw veggies and fruits unless thoroughly cleansed. Be cautious when eating street food during the rainy season.

4. Mosquito control

Use repellents, nets, and long-sleeved clothing. Eliminate stagnant water around your home, where mosquitoes breed. You can order your mosquito repellents and relevant healthcare products online.

5. Boost your immunity

Maintain a well-balanced, vitamin and mineral-rich diet. Consult your doctor before using vitamin C pills.

6. Keep surrounds clean
