Human Metapneumovirus (HMPV), a respiratory virus that often causes cold-like symptoms, has emerged as a health concern in India, with cases being detected across the country. Common symptoms of HMPV include cough, fever, nasal congestion, and shortness of breath. In most adults, the virus leads to mild respiratory issues, but its potential to cause severe complications in vulnerable groups such as children, older adults, and those with weakened immune systems makes it a virus to watch closely. Despite being known primarily as a respiratory infection, HMPV has recently been linked to certain eye-related complications, expanding its impact beyond the lungs. HMPV was first identified by scientists in 2001, though studies suggest it has been circulating among humans since the 1970s. It is a significant contributor to global acute respiratory infections, accounting for 4–16% of cases. Outbreaks of HMPV tend to peak between November and May, and while most adults develop immunity through prior exposure, first-time infections in infants or those with compromised immune systems can lead to more severe manifestations.

Interestingly, experts are now uncovering the viruss potential effects on eye health. According to Dr. Karthikeya R., Senior Consultant at Sharp Sight Eye Hospitals, HMPV has been associated with several eye-related issues in certain cases. Patients have reported symptoms such as redness, swelling, sensitivity to light, and blurred vision, which can be indicative of conditions like conjunctivitis (pink eye), keratitis (inflammation of the cornea), or optic neuritis (inflammation of the optic nerve). While these complications are not common, they can have significant implications for vision if not promptly addressed. Dr. Karthikeya notes that the risk of HMPV-related eye conditions is higher in individuals with weakened immune responses. This includes those undergoing chemotherapy, children whose immune systems are still developing, and older adults whose immunity has declined with age. Without timely medical attention, these conditions can lead to long-term vision issues, making early detection and intervention critical.

Recognizing the potential severity of these complications, experts stress the importance of vigilance during HMPV outbreaks. Individuals experiencing eye discomfort—such as redness, swelling, or blurred vision—alongside respiratory symptoms should seek immediate medical evaluation. Routine ophthalmic screenings for high-risk groups during outbreaks can also play a vital role in identifying and treating issues before they escalate. As there is no vaccine available for HMPV, preventive measures remain the most effective strategy to manage its spread and associated risks. These include maintaining good hygiene, avoiding close contact with infected individuals, and staying vigilant for symptoms. Additionally, raising awareness about the virus’s broader impact on health, including its potential to affect the eyes, is crucial. Integrating eye care into public health strategies during HMPV outbreaks can help mitigate the long-term risks posed by the virus.

The evolving understanding of HMPV highlights the need for a holistic approach to managing its impact. While respiratory symptoms are its primary manifestation, the virus’s association with eye-related complications underscores the interconnected nature of human health. Beyond treating respiratory symptoms, healthcare systems must prioritize eye health evaluations and educate the public about the potential risks to ensure comprehensive care.
