South Sudan announces outbreak of polio

The ministry of health in South Sudan has announced an outbreak of polio in five regional states of the country.

The new outbreak is that of vaccine-derived virus that is linked to low immunisation rates.

In June, the World Health Organization (WHO), Africa region declared South Sudan free of wild polio virus.

However, the new cases were spotted after the first sample turned positive, last month.

A ministry official, Dr John Rumunu says that a nation-wide immunisation campaign targeting over 1.4 million children will be carried out in 45 counties in the affected states starting from first week of November
