Norovirus Associated With The World Athletics Championships
Dr Deborah Turbitt, PHE London deputy director for health protection, said:
"PHE has been notified of a confirmed outbreak of norovirus among people associated with the World Athletics Championships.
"We have so far been made aware of approximately 40 people reporting illness and 3 of these cases have been confirmed as norovirus by laboratory testing.
"PHE has been working closely with the London 2017 organisers and the hotel to provide infection control advice to limit the spread of illness."
Norovirus is often caught through close contact with someone carrying the virus or by touching contaminated surfaces or objects.
Norovirus can be very unpleasant but is rarely serious. Most people make a full recovery within 1 or 2 days, without treatment.
It is important that people with diarrhoea and vomiting drink plenty of fluids to avoid dehydration.
