From ABC News:
Nigerian health authorities raced to stop the spread of Ebola on Saturday after a man sick with one of the world’s deadliest diseases brought it by plane to Lagos, Africa’s largest city with 21 million people.
The fact that the traveler from Liberia could board an international flight also raised new fears that other passengers could take the disease beyond Africa due to weak inspection of passengers and the fact Ebola’s symptoms are similar to other diseases.
Officials in the country of Togo, where the sick man’s flight had a stopover, also went on high alert after learning that Ebola could possibly have spread to a fifth country.
Reportedly, the traveler did not show any signs of Ebola infection when he first boarded the flight. By the time he reached Lagos, he was suffering from diarrhea and vomiting. I’m not sure how long the flights were, but the close proximity of the countries would suggest that his symptoms progressed quite rapidly. That, or his symptoms were ignored when he first boarded the flight. The traveler was identified as Patrick Sawyer, a consultant for the Liberian Ministry of Finance.
I posted about this outbreak before as it’s the largest outbreak ever. It was initially confined within three countries in a regional outbreak. Now, there are two additional countries, Nigeria and Togo, that are on alert and looking for cases. In addition, two US citizens have been infected with the virus while working to help contain and treat the outbreak in Liberia. Both people work in the medical field, and that field has a significant risk due to the proximity of infected persons.
