Hong Kong's second cholera case of the year confirmed
Hong Kong on Friday recorded its second case of cholera in a week when a 32-year-old man who is the son of a woman diagnosed with the disease two days ago was confirmed to also have the disease.
The man in the latest case has been under medical surveillance since he developed diarrhoea early this week.
Laboratory tests showed he was infected with Vibrio cholerae O1 Ogawa, the bacterium that causes cholera, the Centre for Health Protection said on Friday.
The man’s 54-year-old woman was found to have contracted the disease on Wednesday. They are the first two cases of cholera reported in Hong Kong this year.
Both of them remain in hospital in a stable condition. They had no recent travel history, the centre said.
Secretary for Food and Health Dr Ko Wing-man said on Friday the pair were canteen workers at public hospitals. The son worked at Queen Elizabeth Hospital while his mother worked at Queen Mary Hospital.
Ko said the mother and son might have a common source of infection as they had recently eaten seafood bought at a wet market.
“We are now investigating this. Specimens have been taken from the market concerned,” he said.
Ko added that as a precautionary measure, health officers had disinfected the two hospital canteens where the man and woman worked. Their co-workers at both canteens are also being tested for the disease.
Hong Kong recorded two imported cholera cases in 2012, as well as one imported and one local case in 2011.
