A Dane was highly contagious when he flew back to Denmark from a trip to Asia earlier this week.
Denmark had seen no cases of measles since last year. But that has changed now that a Dane has returned from a trip to Asia with the highly contagious infectious disease.
He may have infected others on the flights he took from the Philippines via Hong Kong, or at Copenhagen Airport, and a warning has been issued about the measles scare, the Copenhagen Post reports.
The airport has issued a warning to anyone who may have been in the arrivals or baggage reclaim areas on Monday August 6, particularly between 08:30 and 09:30.
The warning says they should be aware of the symptoms of the disease, even though the virus incubates for the first 10 to 14 days after infection and there are often no signs or symptoms during this time.
Initial signs typically include mild fever, coughing, a runny nose, sore throat and sore eyes, with tiny white spots inside the mouth. A skin rash then appears, usually on the face first. The infection occurs in stages over a period of two to three weeks.
The rash spreads down the arms and body, then down to the legs and feet. The fever rises sharply during this time, before the measles rash gradually recedes.
Straight to hospital
The infected Dane was contagious during his flight home, which included a stopover in Hong Kong, and in Copenhagen he took a taxi direct to the hospital.
The Danish sector research institute Statens Serum Institut has contacted the airlines to obtain a list of passengers on the flights the Dane took in order to warn them.
