Bishkek (AKIpress) - No one knows for sure just how many people Patrick Sawyer came into contact with the day he boarded a flight in Liberia, had a stopover in Ghana, changed planes in Togo, and then arrived in Nigeria, where authorities say he died days later from Ebola, one of the deadliest diseases known to man, the AP reports.
Health experts say it is unlikely he could have infected others with the virus that can cause victims to bleed from the eyes, mouth and ears. Sawyer’s death on Friday has led to tighter screening of airline passengers in West Africa, where an unprecedented outbreak that emerged in March has killed more than 670 people in Guinea, Sierra Leone and Liberia. But some health authorities expressed little confidence in such precautions.
The World Health Organization is awaiting laboratory confirmation after Nigerian health authorities said Sawyer tested positive for Ebola, WHO spokesman Gregory Hartl said. The WHO has not recommended any travel restrictions since the outbreak came to light.
The risk of travelers contracting Ebola is considered low because it requires direct contact with bodily fluids or secretions such as urine, blood, sweat or saliva, experts say. Ebola can’t be spread like flu through casual contact or breathing in the same air.
Patients are contagious only once the disease has progressed to the point they show symptoms, according to the WHO. And the most vulnerable are health care workers and relatives who come in much closer contact with the sick.
Nigerian authorities so far have identified 59 people who came into contact with Sawyer and have tested 20, said Lagos State Health Commissioner Jide Idris. Among them were officials from ECOWAS, a West African governing body, airline employees, health workers and the Nigerian ambassador to Liberia, he said. He said there have been no new cases of the disease.
