Kampala: A 4-year-old child became the second person to die of Ebola in Uganda, the World Health Organization (WHO) said Saturday, in a setback in efforts to end the outbreak that began at the end of January. The child had been hospitalized at the main referral facility in Kampala and died Tuesday, the WHO said in a statement.

According to Qatar News Agency, the WHO added that response teams are working to strengthen surveillance and contact tracing in a bid to curb the spread of the virus. Contact tracing remains a crucial measure to prevent further Ebola spread, especially since there is currently no approved vaccine for the Sudan strain of the virus.
