DATE LAST REVIEWED: 05/11/2026
When to seek further review
- Ask for an urgent GP appointment or call NHS 111 if the fever is getting worse or is not improving with care at home.
- Get urgent advice sooner for shaking chills, poor drinking, much less pee, new pain, a new rash or feeling increasingly unwell.
- Seek medical advice early if pregnant, immune defences are weakened or there is a serious long-term condition. Do not wait a fixed number of days.
- Do not wait for the suggested review time if symptoms become worse, new symptoms appear, or you are worried.
- Contact your GP when the surgery is open. If it is closed, you cannot get the help you need, or you are unsure what to do, call NHS 111. You can call even if you are not sure whether the symptoms are serious.
When to get emergency help
(Immediately dial 999 or go to your nearest Emergency Department)

How to spot sepsis
Sepsis is a life-threatening reaction to an infection. It can get worse quickly. If someone is seriously unwell and may have sepsis, call 999 or go to your nearest Emergency Department. Do not wait for every sign, a high temperature or a rash.
An unwell child under 5 who has not had a pee or wet nappy for 12 hours needs emergency assessment. If you are unsure and there are no emergency signs, call NHS 111 for advice.
