A holiday park that closed after 90 people came down with sickness is reopening today following professional cleaning.

Mullion Holiday Park ending up shutting following the outbreak, which began on Thursday with around 30 children and eight adults affected and an ambulance was called.

It quickly escalated, with 90 cases confirmed by Public Health England (PHE) by Friday.

However, a spokesperson for the park, which is owned by Parkdean Resorts, said the site was reopening today, in time for the half term break for many parts of the country.

He said: "We took the action voluntarily to temporarily close over the weekend, just as a precaution, to make sure it had a full professional clean.

"All the authorities are very happy for us to be reopening today."

He added that PHE had said it would be very hard to determine the the source of the virus into the park, with up to 1,500 guests staying there at any one time.

On Friday PHE confirmed that of the 90 cases of diarrhoea and vomiting that had been reported by that point, two of those were confirmed to be norovirus.

PHE said it was continuing to work with Cornwall Council and other agencies to investigate the outbreak.

Dr Bayad Nozad, consultant in communicable disease control at Public Health England South West, said: “We can confirm that norovirus has been confirmed in two of the cases. The virus usually leads to mild diarrhoea, vomiting and abdominal or stomach cramps that people recover from quickly.

"There is no specific treatment but, if affected, it is important to drink plenty of water to avoid dehydration.

“Norovirus is easily transmitted from one person to another and the virus can survive for some time in the environment.

"Practising good hand hygiene – washing your hands frequently with soap and water is the best way to stop it spreading. Alcohol hand gels don't kill norovirus.

“Our advice for anyone affected is to drink plenty of water to avoid dehydration and stay away from work, school and nursery until you have been symptom free for 48

hours. If symptoms continue, please contact your GP or NHS 111.”

In a statement issued on Thursday, a spokesperson for Mullion Holiday Park said: “We are very sorry that a number of our guests on park have been taken ill, and are carrying out a thorough investigation.

"We immediately contacted Public Health England and the local Environmental Health Authority and are co-operating with them fully to look after our guests whilst we identify the source.”
