How does HMPV infection differ from flu in older adults?

Question

Hello doctor,

A 64-year-old long-term care resident with multiple health conditions is showing symptoms of a respiratory illness, including a fever of 38.7°C, worsening cough, and runny nose. Their oxygen saturation is 92 percent on room air, and a chest X-ray shows patchy infiltrates.

With a cluster of respiratory illnesses in the facility, what infection control measures should be implemented for an HMPV outbreak in the long-term care setting?
How does the progression of HMPV (human metapneumovirus) differ from influenza in older adults with comorbidities?
What is the right testing approach when several respiratory viruses are circulating in the community?

Kindly help.

Hello,

Welcome to icliniq.com.

I understand your concern.

During a human metapneumovirus (HMPV) outbreak in a long-term care facility, strict infection control measures are essential to prevent the virus from spreading. These measures include isolating infected residents, ensuring frequent handwashing and hand sanitizer use by staff and residents, and requiring personal protective equipment (PPE) like masks, gloves, and gowns for those caring for infected individuals. It is also important to regularly disinfect surfaces and shared equipment and limit visitors to reduce the risk of spreading the virus.

In elderly patients, the symptoms of HMPV, such as fever, cough, and a runny nose, are similar to influenza. Still, HMPV can cause more serious respiratory problems, especially in those with existing health conditions. Unlike influenza, there is no specific antiviral treatment for HMPV, so supportive care is used to manage symptoms.

When multiple respiratory viruses are circulating, testing should include multiplex PCR (polymerase chain reaction) panels to detect a variety of pathogens, such as HMPV, influenza, and RSV (respiratory syncytial virus). Rapid antigen tests can also help quickly identify common viruses like influenza. It is important to consider the patient's symptoms and the situation in the facility to guide which tests should be prioritized.
