Dr Arun Ghosh has been selected to join a global group of doctors to discuss the spread of Polio. This is the report by CBBC Newsround from Tuesday 06th May 2014:
Polio worst affects young children, but it can be prevented with a simple vaccine and is almost never found in the UK.
It had been virtually stamped out worldwide, but in a few countries in Asia, Africa and the Middle East there has been a rise in recent years.
One of the worst affected countries is Pakistan - it has had 54 cases of polio so far this year.
This is up from last year when there were 93 cases over the whole year.
Though the numbers may seem small, the World Health Organisation is calling for urgent action.
It wants the governments of these countries to use vaccines to stop the disease from spreading.
- Polio is a virus which affects the brain and spinal cord.
- There is no cure for the disease but it can be prevented by vaccination.
- People of any age can get polio but it mainly affects children under five.
- It spreads through food and water contaminated by human waste .
- Symptoms include fever, being sick and having a stiff neck.
- Most people infected only have mild symptoms but for some it can be very serious and lead to them being paralysed.
