Comparison Between HMPV and COVID-19: What You Need to Know

The global health landscape has been shaken by the emergence of several respiratory viruses, with two of the most discussed being Human Metapneumovirus (HMPV) and COVID-19. Both viruses affect the respiratory system, causing a variety of symptoms that can sometimes overlap, making it challenging to differentiate between them. 

If you're feeling confused or concerned about these viruses and wondering how to protect yourself and others, you're not alone. 

Let’s take a deep dive into the key differences between HMPV and COVID-19 to help clear things up.

What is COVID-19?

COVID-19, caused by SARS-CoV-2, spread globally in 2019, with symptoms ranging from mild to severe, including long COVID. It is unpredictable, with variants bypassing immunity and spreading via droplets and aerosols, even from asymptomatic individuals.

What is HMPV (Human Metapneumovirus)?

HMPV is a respiratory virus, identified in 2001, affecting children, the elderly, and individuals with weakened immune systems. It causes mild to moderate symptoms like cough and fever but can lead to pneumonia, especially in vulnerable groups.

Symptoms

Common Symptoms of HMPV

HMPV often presents with respiratory symptoms that resemble a common cold or flu. These include:

• Coughing
• Fever
• Nasal congestion
• Wheezing
• Shortness of breath

In more severe cases, especially in children and the elderly, it can lead to pneumonia or other serious respiratory infections.

Common Symptoms of COVID-19

COVID-19 symptoms can range from mild to severe, and they may appear 2–14 days after exposure. Common symptoms include:

• Coughing
• Fever
• Shortness of breath
• Fatigue
• Loss of taste or smell
• Sore throat

Some individuals may also experience gastrointestinal symptoms such as diarrhea or nausea. COVID-19 can cause severe respiratory distress, leading to hospitalization or even death, particularly in high-risk populations.

Transmission

How HMPV Spreads?

HMPV primarily spreads through respiratory droplets when an infected person coughs, sneezes, or talks. It can also be spread by touching surfaces contaminated with the virus. The virus is highly contagious, especially in close-contact environments such as daycare centers or nursing homes.

How COVID-19 Spreads?

COVID-19 spreads similarly to HMPV, primarily through respiratory droplets and aerosols, which can linger in the air for extended periods in poorly ventilated spaces. It can also spread by touching contaminated surfaces and then touching the face, although this is less common. Unlike HMPV, COVID-19 can also be transmitted by individuals who do not show symptoms, making it harder to detect and control.

Risk Factors and Vulnerabilities 

Risks for HMPV

While HMPV can affect anyone, the following groups are most at risk for severe illness:

• Young children (especially infants)
• Elderly adults
• Individuals with weakened immune systems or pre-existing respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD). 

Risks for COVID-19

COVID-19 can also affect anyone, but the following groups are at higher risk:

• Older adults (especially those over 65 years old)
• People with underlying health conditions such as heart disease, diabetes, or respiratory conditions.
• Immunocompromised individuals (e.g., those undergoing cancer treatments or with autoimmune diseases).

Both HMPV and COVID-19 can have severe outcomes in these vulnerable populations, making it crucial to take extra precautions.

Diagnosis for HMPV and COVID-19

How is HMPV Diagnosed?

To diagnose HMPV, doctors typically rely on PCR testing or respiratory samples, such as nasal or throat swabs. These tests help confirm the presence of the virus, although they are not as widely used as COVID-19 tests.

How is COVID-19 Diagnosed?

COVID-19 diagnosis primarily involves PCR tests, which are highly accurate. There are also rapid antigen tests available for quick results, although they may not be as reliable as PCR tests. Some regions also use serology tests to detect antibodies and determine past infections.

Treatment and Managing Dreadful Viruses

Treatment for HMPV

Currently, there is no specific antiviral treatment for HMPV. Management typically focuses on relieving symptoms.

• Fever reducers (such as acetaminophen or ibuprofen)
• Hydration
• Rest
• Oxygen therapy in severe cases (e.g., if pneumonia develops)
• Hospitalization may be required for severe cases, especially in vulnerable populations.

Treatment for COVID-19

• Antiviral medications (such as Remdesivir or Paxlovid) may be prescribed for moderate to severe cases.
• Steroids (e.g., dexamethasone) to reduce inflammation in the lungs.
• Oxygen therapy for individuals experiencing difficulty breathing.
• Vaccines and preventive treatments (like monoclonal antibodies) are also essential tools in managing the spread and severity of the virus.

How to Prevent HMPV Infection?

Prevention of HMPV infection is similar to preventing other respiratory infections:

• Hand hygiene (regular hand washing with soap and water)
• Mask-wearing in crowded places, especially during viral outbreaks
• Avoiding close contact with individuals showing symptoms
• Disinfecting surfaces regularly

How to Prevent COVID-19 Infection?

Preventing COVID-19 requires additional measures:

• Vaccination against the virus is the most effective way to prevent severe illness
• Social distancing and mask-wearing in crowded or enclosed spaces
• Good ventilation in indoor areas to reduce the spread of aerosolized particles
• Hand hygiene and avoiding touching the face

Key Differences Between COVID-19 and HMPV

Duration and Severity of Illness

HMPV typically causes milder symptoms that last for a few days to a week, with the majority of individuals recovering without needing medical intervention.

COVID-19 can range from mild to severe, with some individuals experiencing symptoms for weeks or months, particularly in cases of long COVID. Severe cases can lead to hospitalization or death, especially in vulnerable groups. 

Incorporating natural immunity boosters into your diet may help strengthen your immune system, potentially reducing the severity of symptoms and aiding recovery during viral infections.

Long-term Effects

While HMPV typically does not cause long-term effects, some individuals may experience residual breathing difficulties, particularly if pneumonia develops. On the other hand, COVID-19 has been known to cause long-lasting symptoms like fatigue, brain fog, and shortness of breath, which can persist for months after recovery. 

Conclusion

Both HMPV and COVID-19 are respiratory illnesses that can range from mild to severe, with some overlapping symptoms. The key differences lie in their transmission patterns, risk factors, and long-term effects. While HMPV primarily affects children and the elderly, COVID-19 has a much broader impact, with a higher risk of severe illness in various vulnerable populations.

To protect yourself, follow preventive measures such as vaccination (for COVID-19), good hygiene practices, and avoiding close contact with infected individuals. Additionally, including healthy foods for treating HMPV can help boost your immune system and support overall health during viral infections.

If you're unsure whether you have HMPV or COVID-19, seeking medical advice and getting tested is crucial for proper diagnosis and treatment. Understanding these key differences is essential to staying informed and taking the necessary precautions to safeguard your health and the health of those around you.
