Number of whooping cough cases tripled

The number of cases of whooping cough tripled in Sweden last year, according to new figures.

The disease, which is often at most uncomfortable to adults, can be fatal among infants that have not yet been vaccinated.

However, the vaccine given to infants at the age of around six months only protects you from the bacteria for up to ten years, and if you have had the illness as a child, you can still catch it again as an adult.

We spoke to state epidemiologist, Anders Tegnell, from Sweden's Public Health Agency, who says the increased number of cases could be down to adults walking round with an irritating cough, without realising they have actually caught whooping cough and not realising that they could pose a major risk to infants.
