The Ebola virus causes a disease that is often fatal, in part by infecting white blood cells called macrophages and disrupting their immune response. Boston University scientists found that using drugs that block the protein TLR4 can suppress this response and potentially control infection.

Macrophages are responsible for detecting and destroying pathogens, but the Ebola virus activates them through the Toll-like receptor 4 (TLR4) pathway, causing an inappropriate immune response. The Ebola-infected macrophages end up producing excess cytokines and chemokines—proteins that promote inflammation and worsen the disease.

The majority of cases in the world's largest outbreak of Ebola were caused by a tiny handful of patients, research suggests.

The analysis, published in Proceedings of the National Academy of Sciences, shows nearly two thirds of cases (61%) were caused by 3% of infected people.

The young and old were more likely to have been "super-spreaders".

Genomic analysis confirmed that the 2015 death of a 9-month-old Guinean infant from Ebola virus was the result of transmission through the breast milk of her asymptomatic mother, according to a recent case study.

23 DECEMBER 2016 | GENEVA - An experimental Ebola vaccine was highly protective against the deadly virus in a major trial in Guinea, according to results published today in The Lancet. The vaccine is the first to prevent infection from one of the most lethal known pathogens, and the findings add weight to early trial results published last year.

The vaccine, called rVSV-ZEBOV, was studied in a trial involving 11 841 people in Guinea during 2015. Among the 5837 people who received the vaccine, no Ebola cases were recorded 10 days or more after vaccination. In comparison, there were 23 cases 10 days or more after vaccination among those who did not receive the vaccine.

The trial was led by WHO, together with Guinea’s Ministry of Health and other international partners.
