Results showed people travelling from south Asia carried the most bacteria

By examining stools taken from toilets on planes, Danish researchers from the DTU National Food Institute aim to learn how to stop resistant bacteria from spreading across borders.

The scientists examined the content of 18 toilets on planes arriving at Copenhagen Airport from nine destinations in Northern and Southern Asia and North America.

Most bacteria came from South Asia
The preliminary results clearly showed the regions that travellers bring the most bacteria from.

“It was crystal clear, perhaps too clear, that passengers visiting Southern Asia had been infected by many resistant bacteria and brought them home with them,” Frank Moller Aarestrup, a professor at DTU, told DR.

Getting a better overview
The Danish researchers believe they can use the insights from their experiment as a stepping stone to finding a cure for all infectious diseases worldwide.

“We can use our knowledge to learn what diseases are in the different countries because, as of today, many countries don’t have a proper overview,” Aarestrup commented.

“We can also use it to see which infections are being carried around and spread from one country to another.”

A survey carried out by Megafon for TV2 has found that 71 percent of parents have handed over children to daycare in spite of them being sick.

Moreover, 21 percent of those surveyed admitted to medicating their kids with paracetamol, such as Panodil, before sending them to school.

The FOLA parents’ organisation is shocked by the findings.

“I think it is absolutely crazy. It simply cannot be that a child goes to school sick and plays with lots of other children. Then we are faced with the fact that they will infect the whole institution,” said FOLA chair Signe Nielsen.

Pill pushers
At the Børnehuset daycare institution in Silkeborg a meeting was called where parents were implored not to bring their sick children to school.

At Børnehuset there are fears that parents prefer to pack their kids off with a pill without informing teachers.

“We occasionally have children who that they have had a pill for breakfast,” said headteacher Susanne Bødker. “You might think that it is a Panodil more than a vitamin pill, if it is a child who has just been sick, for example.”

Parents sick and tired
Parents, when confronted, often cite pressure at work as a reason for not being able to stay at home with their children.

Many declare that they simply cannot take another day off, as they are afraid of being fired.

Allan Randrup Thomsen, a professor of virology at KU, has heavily criticised the parents’ actions, describing the current situation as a “vicious circle”.

“It promotes the spread of viruses, and it adds momentum to a cycle where parents are pressured by high levels of sick-leave. If they then choose to send the children to daycare while they are still recovering, they keep the epidemic going in daycares, and this in turn puts a greater burden on the parents.”
