Current HMPV Trends in the UK

Current HMPV Trends in the UK

Rising Positivity Rates: According to the UK Health Security Agency (UKHSA), HMPV positivity rates reached 4.2% in late January 2025, up from 3.8% the previous week 13. By mid-January, 5% of hospital respiratory swabs tested positive for HMPV, marking the highest rate this winter 814.

Vulnerable Groups: The elderly (aged 80+) and young children (under five) are disproportionately affected, with positivity rates as high as 7.3% and 7%, respectively 1417.

Seasonal Patterns: HMPV typically peaks in winter, aligning with trends seen in previous years. Current activity is classified as "medium" by UKHSA, consistent with expected seasonal levels 18.

Symptoms and Severity

HMPV mimics common cold or flu symptoms, including:

Cough, nasal congestion, sore throat, and fever 212.

Severe cases may progress to bronchitis, pneumonia, or bronchiolitis (in infants), particularly in immunocompromised individuals 815.

Symptoms typically resolve within a week for mild cases but can persist longer in high-risk groups

Why Is HMPV Gaining Attention?

Global Context: Reports of HMPV outbreaks in China, India, and Malaysia sparked initial alarm, with social media images showing overwhelmed hospitals. However, experts clarify that these surges are seasonal and not linked to new, dangerous strains 26.

Comparison to COVID-19: Unlike SARS-CoV-2, HMPV has circulated for decades, and population immunity limits its pandemic potential. Mutations are gradual, reducing the risk of explosive spread.

Protecting Yourself and Others 

Hygiene Measures: Frequent handwashing, disinfecting surfaces, and covering coughs/sneezes remain critical .

Mask-Wearing: UKHSA advises wearing masks in crowded spaces if symptomatic, especially around vulnerable individuals .

Vaccination Gaps: While no HMPV vaccine exists, staying updated on flu and COVID-19 shots can reduce co-infection risks .

NHS Strain and Public Health Response

The NHS faces dual pressures from flu and HMPV, with hospitals reporting ~5,000 flu patients and critical incidents declared in regions like Birmingham and Liverpool . Amanda Pritchard, NHS England CEO, acknowledged the strain but emphasized preparedness through expanded bed capacity and early symptom management .

 Expert Reassurances

No Cause for Panic: Dr. Conall Watson (UKHSA) notes HMPV levels are "in line with expectations" for winter 17.

Ongoing Research: Scientists at the University of Oxford are testing mRNA vaccines targeting HMPV and RSV, though approvals are years away 6.

Key Takeaways

HMPV is a seasonal virus with mild symptoms for most but severe risks for vulnerable groups.

Current UK rates are elevated but not unprecedented.

Preventive measures mirror those for flu and COVID-19.

Health services are managing the surge, but public vigilance is crucial.
