We are currently working with partners to manage a small cluster of meningitis cases in the Reading area. Meningitis is a serious illness - knowing the symptoms can save lives: ukhsa.blog.gov.uk/2025/10/31/what-i…

How common is meningitis in England?
Around 300 to 400 cases of meningococcal disease are diagnosed in England every year. The vast majority of infections involve only a single case. Outbreaks are rare and typically involve 2 to 4 cases.

How common is meningitis in England?
Fast-spreading outbreaks, such as the Kent cluster in March 2026, with 21 cases in a very short time, are highly unusual.

Meningitis symptoms
A rash will not always appear. Symptoms of meningitis develop suddenly and can include:
• a high temperature (fever)
• being sick
• a headache
• a rash that does not fade when a glass is rolled over it (but a rash will not always develop)
• a stiff neck
• a dislike of bright lights
• drowsiness or unresponsiveness
• seizures (fits)
Call 999 or go to your nearest A&E immediately if you think you or someone you look after could have meningitis or sepsis.

Our latest data shows chronic hepatitis C cases in England have dropped 61% since 2015: from 129,000 to around 50,200 adults in 2024. Among people who inject drugs, infection rates have fallen from 28.6% in 2015 to 5.2% in 2024.

Dr Monica Desai, Head of the Hepatitis Section at the UKHSA, said:
We are making significant progress towards eliminating hepatitis C.
The sharp fall in cases since 2015 shows the impact of expanded testing and sustained access to modern curative treatments and the commitment of health services and community partners across England. While the number of people living with the virus continues to decline, it remains vital that those most at risk are offered testing, can access life-saving treatments, and receive the support needed to prevent new infections.

Conall Watson, Consultant Epidemiologist, RSV lead at UKHSA said:
“RSV lung infection is less well known than COVID or flu but for older adults it can be particularly dangerous and puts thousands in hospital each year with a risk to life.
New evidence today from the UK public health agencies shows the vaccine cuts your risk of being hospitalised by around 75% – so it’s great news that the vaccine is now available to everyone aged 75 and over, including all those aged over 80. And we also know that the RSV vaccine for pregnant women is providing excellent protection to newborn babies. If you’re eligible, be sure to take up the offer and get the best protection possible against a nasty case of RSV pneumonia.”

While this mosquito-borne infection is rarely fatal, it can cause severe joint and muscle pain, headaches, sensitivity to light and skin rashes.

This preliminary analysis offers strong reassurance that our existing vaccinations and antibiotic treatment offer will be effective against this strain.

In collaboration with the research community, we will continue intensive laboratory investigations of the strain to determine how the spread of the outbreak may have been influenced by the bacterial strain, social or environmental conditions, and population immunity.
