As instances of hMPV rise, many concern one other pandemic like Covid-19. Nonetheless, they don’t seem to be the identical virus. Listed below are 7 key variations between hMPV vs Covid-19.
Lately, an 80-year-old man in Ahmedabad examined constructive for human metapneumovirus (hMPV), including to the rising instances of hMPV in India. This has sparked confusion among the many public, with many mistakenly considering hMPV and Covid-19 are the identical virus. Whereas each are respiratory diseases, they’re brought on by fully completely different viruses and have distinct traits. Not solely this, however regardless of some similarities in signs and transmission, these two viruses require completely different approaches to prevention and therapy. Due to this fact, understanding the variations between hMPV vs Covid-19 is essential—not solely to keep away from pointless panic a couple of new pandemic but in addition to handle these infections extra successfully.
Variations between hMPV vs Covid-19
Listed below are 7 variations between these two respiratory infections, hMPV vs Covid-19:
1. Totally different teams of virus
HMPV vs Covid-19 are brought on by fully completely different households of viruses.
- HMPV belongs to the Paramyxoviridae household, a bunch of viruses that additionally contains the respiratory syncytial virus (RSV), based on the Facilities for Illness Management and Prevention (CDC).
- In distinction, Covid-19 is an infectious illness brought on by the SARS-CoV-2 virus, which is a part of the Coronaviridae household, as per the World Well being Group (WHO).
These two viral households differ considerably when it comes to construction, replication mechanisms, and the way they work together with the human immune system.
2. Seasonal transmission patterns
One notable distinction between hMPV vs Covid-19 is their seasonal patterns.
- HMPV primarily circulates in colder months, particularly throughout winter and early spring, making it seasonal in nature.
- Alternatively, Covid-19 has confirmed to trigger year-round transmission. Whereas it will probably peak in sure seasons, like throughout winter when respiratory infections are extra widespread, Covid-19’s unfold is influenced by a number of components, together with the emergence of latest variants, which implies it will probably stay prevalent all year long.
3. hMPV isn’t new
- HMPV isn’t a brand new virus, it was first recognized in 2001 and has been circulating for a few years. Most individuals have encountered the virus in some unspecified time in the future, that means there’s a normal stage of immunity within the inhabitants, particularly in those that have been contaminated as kids.
- Covid-19, nevertheless, is a novel virus that emerged in late 2019. Because it was beforehand unknown to the human immune system, nobody had innate immunity to it, resulting in widespread world infections and fatalities.

4. Severity of signs
- HMPV is usually related to delicate to reasonable cold-like signs akin to cough, runny nostril, sore throat and fever. In high-risk people, akin to infants, aged folks, and people with weakened immune techniques, it will probably progress to extra critical circumstances like bronchiolitis or pneumonia, reveals the American Lung Affiliation. Nonetheless, even in these instances, the illness is normally much less extreme than Covid-19.
- Extreme instances of Covid-19 might result in pneumonia, acute respiratory misery syndrome (ARDS), multi-organ failure, and even dying, as per the Mayo Clinic. It additionally has a wider array of systemic signs, akin to lack of scent and style, muscle aches, and gastrointestinal points, which aren’t sometimes related to hMPV.
5. Transmissibility
- HMPV is much less transmissible and doesn’t unfold as effectively as Covid-19. It primarily impacts younger kids, the aged, and people with compromised immune techniques, and its transmission is much less widespread.
- Covid-19 is extra transmissible than hMPV. SARS-CoV-2 spreads extra simply attributable to its potential to quickly mutate into new variants, a few of that are extra contagious than earlier strains.

6. Goal populations
- Whereas each viruses can have an effect on varied age teams, hMPV predominantly targets younger kids, particularly infants, older adults, and folks with weakened immunity, suggests the Facilities for Illness Management and Prevention (CDC). Its results are extra pronounced in these teams, doubtlessly resulting in critical respiratory sickness.
- Covid-19, nevertheless, can have an effect on people of all ages, with extreme instances seen in each older adults and younger adults with underlying circumstances. Though kids can get contaminated with Covid-19, they’re usually much less more likely to expertise extreme outcomes in comparison with adults, states a examine printed in Viruses.
7. Availability of vaccines
One other important distinction is the supply of vaccines.
- There is no such thing as a vaccine for hMPV, though analysis into growing one continues.
- In distinction, World Well being Group-approved Covid-19 vaccines, akin to Pfizer–BioNTech, Oxford–AstraZeneca, Covaxin, Novavax, and so on., have been broadly developed and distributed globally, offering immunity towards the virus.
Similarities between hMPV vs Covid-19
Listed below are 5 widespread issues between hMPV vs Covid-19 respiratory infections:
1. Impacts the respiratory system
Each hMPV vs Covid-19 primarily goal the respiratory system, inflicting signs like cough, fever, sore throat, and nasal congestion. They will result in extreme lung infections, akin to pneumonia, particularly in high-risk people just like the aged, kids, and people with underlying well being circumstances.
2. Seasonal infections
Although Covid-19 circulates year-round, each viruses unfold extra in colder months. Respiratory viruses akin to hMPV vs Covid-19 are likely to thrive in colder and drier air, resulting in greater transmission throughout winter and spring.
3. Related prevention measures
Prevention for hMPV vs Covid-19 contains frequent handwashing, overlaying the nostril and mouth with a face masks, bodily distancing, and avoiding crowded areas. Since each unfold by way of respiratory droplets, training good hygiene and minimising shut contact with contaminated people helps cut back transmission.
4. Asymptomatic instances
Each hMPV vs Covid-19 could be unfold by asymptomatic people. Whereas asymptomatic instances are extra widespread with Covid-19, hMPV can be carried with out noticeable signs, which makes it necessary to observe all of the preventive measures even when feeling nicely to scale back the transmission.
5. Probably life-threatening
Sure, each viruses could be lethal, notably for weak teams. hMPV may cause extreme respiratory failure, whereas Covid-19 has led to tens of millions of deaths worldwide, particularly throughout the early stage of the pandemic. Each may end up in critical problems in vulnerable people.

Associated FAQs
Are there vaccines for hMPV and Covid-19?
Presently, there isn’t a particular vaccine for hMPV, although analysis is ongoing. For Covid-19, there are a number of vaccines out there which have confirmed efficient in lowering the severity of sickness.
How are hMPV and Covid-19 identified?
Each viruses are identified by means of PCR checks, which detect viral RNA. Covid-19 can be identified by means of antigen checks, which give faster outcomes, although they might not be as correct as PCR checks.
