WHO says water contamination is suspected in one of the Congo villages struck by illness

Authorities investigating the deaths of at least 60 people in northwestern Congo suspect the water source in one of the areas may have been contaminated, the World Health Organization said Friday. But the agency said it's too early for any definitive conclusion.

Doctors are investigating more than 1,000 illnesses that emerged since late January in five villages in Congo's Equateur province, where high rates of malaria have complicated efforts to diagnose the cases and where officials have said they've been unable so far to confirm the main cause.

WHO emergencies chief Dr. Michael Ryan said during an online briefing Friday that for one of the villages there is “a very strong level of suspicion of a poisoning event related to the poisoning of a water source."

Ryan did not clarify whether he was referring to contamination by accident, negligence or deliberate action. He also did not identify the village where the poisoning was suspected.

"We will not stop investigating until we are sure that the true cause or the absolute cause of what is occurring here is fully investigated,” Ryan said.

Illnesses were first detected in late January in the village of Boloko after three children ate a bat and died within 48 hours.

Twelve cases and eight deaths in total have been recorded in Boloko, with no new cases recorded since January, officials say, adding that nearly half of deaths there occurred within hours of the onset of symptoms.

The village of Bomate in Basankusu health zone, around 200 kilometers (125 miles) from Boloko, has been hit the most: 98% of the cases and 86% of deaths have been recorded there, health officials say.

WHO said on Thursday that hundreds of the patients have tested positive for malaria, which is common in the region. In addition to common malaria symptoms such as fever and body aches, patients have also shown symptoms like chills, sweating, stiff neck, runny or bleeding nose, cough, vomiting and diarrhea.

The health crisis has caused fear among residents, some of whom have said they fled the villages to avoid falling sick.

Experts say access to the sick has been hindered by the remote locations of the affected villages and that several people died before medical teams were able to reach them.

The World Health Organization on Friday said water poisoning is a suspect in the illnesses that have killed at least 60 people and infected more than 1,000 others in northwestern Congo. The agency, however, added that detailed investigations are still ongoing to make a definitive conclusion.

Indications from authorities in Congo show "a very strong level of suspicion of a poisoning event related to the poisoning of a water source” in one of the affected villages, WHO emergencies chief Dr. Michael Ryan said during an online briefing.

"Clearly, at the centre of this, we have some kind of poisoning event. We will not stop investigating until we are sure that the true cause or the absolute cause of what is occurring here is fully investigated,” Dr Ryan said.

Another likely suspect could be a "toxic-type event either from a biological perspective like meningitis or from a chemical exposure,” the WHO emergencies chief said, citing systematic investigations carried out so far by experts.

Officials, though, haven’t been able to confirm the main cause of the illnesses, he said, adding that the high rates of malaria and other common illnesses in the villages are making it difficult to determine the cause.

Up to five villages in Congo's Equateur province have recorded the illnesses first detected in the village of Boloko after three children ate a bat and died within 48 hours.

Twelve cases and eight deaths in total have been recorded in Boloko, with no new cases recorded since January, officials say, adding that nearly half of deaths there occurred within hours of the onset of symptoms.
