A sudden spike in cases of vomiting and diarrhoea has triggered a health alert in Gibraltar, with authorities linking the outbreak to the highly contagious Norovirus.
Public health officials say the virus is spreading rapidly, particularly in enclosed environments, raising concerns on both sides of the border.
The situation is causing particular concern in the nearby Campo de Gibraltar, where thousands of Spanish workers cross the frontier daily.
Health experts warn this constant movement of people could accelerate the spread of the virus between Gibraltar and southern Spain if precautions are not followed.
‘Highly contagious’ warning
The Gibraltar Health Authority (GHA) has issued clear guidance aimed at limiting transmission, especially in high-risk settings such as hospitals and care homes.
Anyone experiencing symptoms such as vomiting or diarrhoea is being urged to:
- Avoid visiting hospitals or care homes
- Stay away from vulnerable individuals
- Wait at least 48 hours after symptoms stop before resuming normal activities
The same rule applies to children returning to school.
Public Health Director Helen Carter stressed that the virus can pose a serious risk to vulnerable groups if not contained.
Appointments may need to be delayed
Residents with upcoming medical appointments – including consultations or scans – are being advised to contact health services if they have recently been unwell, in order to reschedule and prevent further infections.
What is norovirus?
Norovirus is one of the leading causes of acute gastroenteritis worldwide.
It spreads through contaminated food or water, infected surfaces and direct contact with an infected person.
Symptoms typically appear suddenly and include vomiting, diarrhoea, stomach pain and, in some cases, dehydration.
Most people recover within one to three days, but the illness can be more serious for young children, the elderly and those with weakened immune systems.
Key advice: wash your hands
Authorities are also warning about hygiene. Frequent handwashing with soap and water remains the most effective way to stop the virus spreading.
Crucially, experts stress that hand sanitiser alone is not enough to kill norovirus, meaning basic hygiene is still the best defence.
Health officials are also monitoring more transmissible strains of the virus, including the GII.17 variant, which has been linked to rising outbreaks globally.
