Congo tests passengers after boat that carried suspected Ebola case intercepted near Kinshasa

Congolese health authorities are screening over 300 people on a river boat after a passenger's suspected Ebola death raised concerns the virus may have spread on board.

Congolese health authorities were screening more than 300 people ​travelling on a river boat intercepted near Kinshasa ​on Thursday after the death ‌of a passenger ​suspected of having Ebola raised concerns the virus may have spread on board, officials said. Authorities deployed a mobile laboratory to the vessel after it ‌was stopped in Maluku, around 65 km (40 miles) upstream from the capital on Wednesday.

The secretary-general of Congo's health ministry, Body Ilonga Bompoko, said all passengers were undergoing temperature checks and clinical screening. He told reporters samples had ‌been collected from four passengers with symptoms including fever and sent for testing, with results expected on Friday.

QUESTIONS ‌OVER SUSPECTED CASE The operation was launched after health authorities in Mongala province reported the death on July 25 of a 32-year-old man suspected of having Ebola who was believed to have travelled on the vessel.

Officials have given differing accounts of the man's movements ⁠and ​where he may have ⁠contracted the virus. Africa CDC Director General Jean Kaseya told reporters on Thursday the boat came from Mongala province, where no Ebola cases ⁠have been recorded, rather than from Tshopo province, where the outbreak has spread. Congolese authorities had earlier identified Kisangani, the ​capital of Tshopo, as the vessel's point of origin.

Kaseya also said the man fell ill while ⁠travelling on the vessel, while Congo Health Minister Samuel Roger Kamba said on Wednesday that he developed symptoms only after disembarking. Mongala provincial ⁠health ​chief Eustache Bibala Faray said authorities had not established where the man boarded the vessel. Health officials initially linked him to Kisangani because documents found on him indicated he was from there, he told ⁠Reuters.

VACCINES, TREATMENTS TO BE EXPANDED Separately, Kaseya said authorities had decided to expand use of a vaccine developed against ⁠the Zaire ebolavirus species after ⁠data suggested it provided some protection against the Bundibugyo species driving the current outbreak.

He said authorities also planned to expand use of the antiviral drug remdesivir ‌in affected areas.
