The UK Health Security Agency (UKHSA) has issued a warning about a significant uptick in flu cases, emphasizing that more adults are now being impacted. This comes as the agency, through a recent alert on X (formerly known as Twitter), highlighted that flu is circulating at what they describe as “medium levels.” The weekly positivity rate has seen a notable rise, climbing from 11.6% to 17.1%.

In the week leading up to Sunday, November 30, there was also a marked increase in hospital admissions due to flu. The rate of hospitalizations surged from 4.78 to 7.79 per 100,000 individuals, underscoring the escalating situation.

Flu symptoms tend to manifest suddenly and can include a high fever, muscle aches, fatigue, and a persistent dry cough. For most people, these symptoms can be managed at home. It is recommended to get plenty of rest, use paracetamol or ibuprofen to alleviate pain, and stay hydrated by drinking ample fluids.

Nonetheless, there are specific groups who should be particularly vigilant and seek prompt medical attention if they display flu symptoms. This advice is particularly relevant for pregnant women, individuals aged 65 and older, and those with existing chronic health conditions like diabetes or heart disease.

Most people can treat their symptoms at home with lots of rest, taking paracetamol or ibuprofen for pain management, and drinking plenty of fluids.

However, certain high-risk groups should seek urgent medical care if they experience flu symptoms. This includes pregnant women, those aged 65 and above, and people with chronic medical conditions such as diabetes or heart disease.

According to NHS guidance, you must call 999 or head straight to A&E if you or a child coughs up a substantial amount of blood, experiences breathing difficulties, or develops sudden, severe chest pain.

You should avoid driving yourself to A&E and ask for a lift or call an ambulance instead. And make sure to take any medications you’re currently using with you.

The UKHSA reported that respiratory syncytial virus (RSV) cases have also risen week on week.

Hospital admissions increased from 2.38 to 3.75 per 100,000 people, whilst positive test results climbed from 8.7% to 10%.

However, positive Covid tests dropped from 2.3% to 2.1%, while hospitalisations due to Covid saw a slight rise from 0.88 to 1.03 per 100,000 of the population.
