How Can HMPV Affect The Lungs?

According to studies, the HMPV virus is responsible for about 10 percent of hospitalizations due to respiratory illnesses globally. It is an emerging respiratory virus known for causing problems ranging from mild respiratory infections to severe complications like blood in the sputum. It is closely linked with the respiratory syncytial virus and spreads through respiratory droplets, direct contact, or touching contaminated surfaces, making it more contagious during seasonal outbreaks specifically. If you notice any of the symptoms of the HMPV virus, it is vital for you to immediately contact the best lung doctor to get yourself checked and start your treatment. Dr. Arvind Kumar is among the top thoracic doctors in Delhi who can help you out with this. He has many years of experience in performing many significant and complex thoracic surgery cases via open, VATS, and robotic assistance.

Causes of HMPV virus 

Human Metapneumovirus is caused by a virus from the Paramyxoviridae family that affects the respiratory system, including the lungs and airways. The virus spreads from an infected person’s cough, talk, and sneezes by releasing the droplets into the air. It can also be passed with direct contact with a person who is infected by touching surfaces that they contaminate. However, the exact cause of HMPV is still unclear; it tends to spread more in colder months when respiratory infections are too common. Some common causes of HMPV are :

• Seasonal patterns can cause HMPV as infections are more common during winter as well as early spring.
• Environmental factors also contribute, as crowded indoor spaces with poor ventilation can cause viruses to spread quickly, such as HMPV.
• Co-circulation with other pathogens is also the cause, as the simultaneous circulation of HMPV with other respiratory viruses, such as influenza and COVID-19, can complicate its diagnosis and treatment.
• Genetic changes are also some of the causes. Like all other viruses, HMPV can mutate over time, which can lead to more transmissible or virulent strains.

Groups of people who are at high risk of experiencing the HMPV severe illness 

Certain groups of people are more at risk of experiencing severe complications from HMPV, and these are:

• Infants, as well as young kids above five years old, because their immune systems are still developing and have smaller airways that can make it harder to fight the infection.
• Older people above 65 years old are more at risk because of their underlying issues. Their weak immune system cannot respond properly to the virus, which puts them at more risk.
• People with weakened immune systems, like those who undergo cancer treatments or live with AIDS or HIV, are at greater risk of severe infections and complications.
• People with existing lung or heart conditions like COPD, asthma or heart disease as these conditions already place extra strain on the respiratory system.

These groups of people must take extra care of themselves. By understanding human metapneumovirus and its associated risks, individuals can take vital measures to manage and prevent this prevalent respiratory illness. Also, people have to keep in mind that the spread of HMPV infection can be reduced by practicing good hygiene and respiratory etiquette and avoiding close contact with infected people. If any of the people you know are experiencing difficulty in breathing or chest pain, or if symptoms are worsening despite proper rest and taking of fluids, then it is essential to seek instant medical treatment from the best lung doctor like Dr Arvind Kumar.

Symptoms of HMPV 

HMPV primarily affects the respiratory system and is known to cause many illnesses, from mild cold-like symptoms to severe respiratory complications like bronchitis and pneumonia. However, the virus can easily infect people of all ages; it poses a risk to young children, elderly adults, and people with weak immune systems. HMPV is a virus that affects the upper and lower respiratory tract, and symptoms may range from severe to life-threatening as well. The symptoms may vary from person to person depending on age, health, and immunity. Some may experience mild illness, and others may develop more severe symptoms, such as blood in the sputum in the morning when clearing the throat.

Some common mild respiratory symptoms of HMPV include:

• Runny nose
• Stuffy nose
• Fever
• Cough
• Sore throat
• Fatigue and malaise

Some high-risk symptoms of the HMPV virus are

• Shortness of breath
• Chest pain
• Wheezing
• Rapid breathing
• Cyanosis

How does HMPV affect the lungs?

HMPV virus can affect both the upper and lower respiratory tracts, affecting the lungs severely along with the respiratory tract. It is considered a contagious lung disease that causes cold-like symptoms and is thus ignored by many and raises the risk of serious issues like bronchitis and pneumonia. HMPV affects the lungs, and most of the cases are mild, but serious complications can also occur in high-risk people. HMPV severely affects the lungs and develops complications, including :

• Bronchitis – inflammation and swelling of the small airways in the lungs that causes breathing difficulty and wheezing.
• Blood in phlegm, no cough– HMPV virus infection can also develop blood in phlegm and indicate a moderate to severe illness that is due to inflammation in the airways that can cause bleeding, and that too without the cough.
• Pneumonia – the lung infection can lead to fever, difficulty in breathing, and chest pain and may even require hospitalization.
• Asthma exacerbation– HMPV triggers and can worsen asthma symptoms that can lead to increased wheezing, breathing issues, and coughing.
• Respiratory failure – It can severely impact breathing, and the patient may need oxygen therapy and mechanical ventilation as well.

However, HMPV resembles a cold with some common symptoms, including runny nose, sore throat, and cough. But it can cause severe respiratory issues in older and younger kids. There is a difference between cold and HMPV in terms of severity, complications, recovery time, and treatment as well.

Diagnosis of HMPV 

HMPV can be diagnosed on the basis of the individual’s medical history, symptoms, and risk factors. The lung specialist will collect a sample from the nose or throat with a soft-tipped swab, and the sample is then sent to the lab, where specialized tests are done. The test includes :

• Polymerase chain reaction or viral culture that is used to detect the presence of HMPV or other respiratory infections as well. Also, for patients with severe symptoms of HMPV or if they have any underlying health issues, some extra tests are recommended like :
• Chest X-ray
• CT scans to identify lung changes
• Bronchoscopy , is conducted to examine the airways for inflammation or blockages
• Blood tests may also be required to detect out bacterial infections or to evaluate immune response

Treatment for HMPV virus infection

When you notice any of the above-listed mild to severe symptoms of HMPV, you must consult the lung doctor immediately. However, there is no specific treatment or vaccine available for HMPV infections, but the condition can be managed well by focusing on alleviating symptoms and offering supportive care. The doctor will :

• Advise taking proper rest and staying hydrated, as this will support the body’s natural healing process.
• Also, the over-the-counter medications will get prescribed to reduce fever and to get relief from pain and discomfort.
• Nasal decongestants and saline sprays are also employed to relieve nasal congestion and improve breathing.
• Humidifiers are also recommended to add moisture to the air and, which soothe irritated airways and also ease coughing.
• Oxygen therapy is also provided to give supplemental oxygen to people with breathing difficulties.
• Bronchodilators are used to open up airways in patients with shortness of breath and wheezing.
• Antibiotics are also prescribed only if there is a secondary bacterial infection.

However, most HPV infections resolve on their own with rest. However, if anyone experiences severe symptoms, then it is better to consult the best lung doctor for intensive medical support. Recovery from the same may take about two weeks as most symptoms, like fever and cough, improve within a few days after proper treatment. Some high-risk groups may experience prolonged recovery, but by taking adequate rest and staying hydrated, it can be fully cured.

When to seek Thoracic expertise?
