The World Health Organization is gearing up to test vaccines to stop the spread of the new Marburg virus, but if anything, Africa's flare-up is showing just how unprepared the world still is for outbreaks like these: 📸: Science Source
The World Health Organization is now planning to start trials of some of the experimental vaccines using what’s known as ring vaccination. “It means we will offer the vaccine to the close contacts of the cases,” says Ana-Maria Henao Restrepo, co-lead of the WHO’s R&D Blueprint for epidemics. “This is, in our experience, about 20 to 50 people, depending on the social network of each case.
This would patch up one hole in the Marburg response, but there are still others. In Tanzania, two weeks passed between the fisherman’s death and authorities announcing the spread of the then unknown illness. By that point, three of the fisherman’s family had also died from the virus. And if a virus like Marburg is spreading, being able to do genetic sequencing locally is particularly useful; it helps researchers keep track of any changes to the virus, and how these could affect patients. But in countries like Tanzania and Equatorial Guinea, sequencing capacity is limited.
