India may extend medical aid to Ebola-affected regions as it enhances surveillance, following WHO's public health emergency declaration.

WHO said 80 suspected deaths, eight confirmed cases and 246 suspected cases had been reported so far in the Democratic Republic of Congo and Uganda.

The World Health Organization said the Ebola outbreak could be much larger than what is currently being detected and reported. It warned of health risks to other countries.
