Polio eradication programme reaches 'major milestone'

A “major milestone” in the battle to eliminate polio globally has been reached, the US Centres for Disease Control (CDC) has said.

Its experts think a second of the three forms of poliovirus has been eliminated after mass vaccination campaigns.

Wild poliovirus type 3 has not been detected for more than two years. Type 2 was eradicated in 1999.

Experts said the world was “closer than ever” to defeating polio but the situation in Pakistan was worrying.

Polio is highly infectious and causes paralysis in up to one in 200 people. Some children die when the muscles that help them breathe stop working.

But there has been huge progress in eliminating the disease. Cases have fallen from 350,000 in 1988 to 416 in 2013.

The last case of type 3 poliovirus was detected in Pakistan in November 2012, according to the CDC report.

“We may have eradicated a second of three; that’s a major milestone,” said Dr Stephen Cochi, a senior adviser at the CDC’s Centre for Global Health.

However, a formal process – involving the Polio Global Certification Commission – is required before type 3 can be officially declared eradicated. That will not take place for at least another year.
