Understanding Isolation Guidelines for Human Metapneumovirus (HMPV): Protecting Yourself and Others
Human Metapneumovirus (HMPV) is a significant respiratory virus that primarily affects young children, older adults, and immunocompromised individuals. Known for causing a range of illnesses from mild respiratory infections to severe conditions like bronchiolitis and pneumonia, HMPV has been under increased scrutiny following a rise in cases globally, including detections in Karnataka, India.
In light of these developments, all Indian states have been advised to enhance surveillance for Severe Acute Respiratory Illnesses (SARI) and Influenza-Like Illnesses (ILI). The Union Ministry of Health has issued specific directives to bolster testing efforts and prevent the virus’s spread.
To monitor and contain the spread of HMPV, the Integrated Disease Surveillance Programme (IDSP), in collaboration with state health departments, has issued guidelines for testing and tracking cases. As per health officials:

When is HMPV Most Contagious? The most contagious phase of HMPV occurs during the early days of the infection, typically between 3 to 6 days after the onset of symptoms. According to experts:
HMPV spreads through respiratory droplets (from coughing or sneezing) and fomites (contaminated surfaces). Therefore, the risk of transmission is significantly higher during close contact with an infected person.
Preventing the spread of HMPV requires adopting standard hygiene practices and maintaining physical distancing. Key steps include:
Maintain Physical Distancing:
Practice Hand Hygiene:
Wear Masks:
Cough Etiquette:
Sanitise Surfaces:
Avoid Handshakes:
