Ebola intensifies in Kampala, Uganda

Since Uganda’s Ebola outbreak began in September, the health ministry has recorded 109 cases and 30 deaths.

Now, six children in the same Kampala family have contracted the virus, authorities in the capital say.

As the virus spreads, there is growing concern that it could reach other countries.

Viruses can spread faster in densely populated areas and this particular strain of Ebola - called the Sudan strain - has no vaccine yet.
