The findings, published in the journal Nature Communications, show that the virus acquired mutations before it spread globally. These mutations, which are absent from forms of the virus currently circulating in parts of Africa, cause less severe symptoms in patients, who may have unknowingly spread the virus across borders. https://medicalxpress.com/news/2026-09-mpox-outbreak-severe-virus-reveals.html Tue, 08 Sep 2026 17:20:07 EDT news708105182 The current outbreak of Bundibugyo virus (BDBV) in the Democratic Republic of the Congo highlights the challenges of responding to rare but potentially devastating infectious diseases. Two studies led by researchers from the German Center for Infection Research (DZIF), together with other national and international collaborators, now provide important insights for outbreak response. One study demonstrates how diagnostic tests can be evaluated rapidly during an outbreak; the other investigates the biological properties of the 2026 BDBV strain and whether an existing Ebola vaccine could offer some cross-protection. Both studies were published this month in The Lancet Infectious Diseases. https://medicalxpress.com/news/2026-09-responses-bundibugyo-virus-outbreaks-faster.html Tue, 08 Sep 2026 15:20:09 EDT news708093961 Scientists in China have identified a novel tick-borne virus that causes an influenza-like illness characterized by fever, fatigue, gastrointestinal (GI) symptoms and abnormal lab findings.
