Pathogens behind Respiratory Illnesses in Uganda Identified

A study led by researchers at Center for Infection and Immunity (CII) reports on the use of a genetic sequencing method to identify viral pathogens behind unexplained respiratory illnesses in Uganda over a five-year period. The method, called VirCapSeq-VERT and developed at CII, identified nine clusters of infections, including one potentially related to tourism from the U.K.

Virus Transmission: Highly Infectious Vehicle Discovered

Researchers have found that a group of viruses that cause severe stomach illness—including the one famous for widespread outbreaks on cruise ships— get transmitted to humans through membrane-cloaked "virus clusters" that exacerbate the spread and severity of the disease. Previously, it was believed that these viruses only spread through individual virus particles.

The discovery of these clusters, the scientists say, marks a turning point in the understanding of how these viruses spread and why they are so infectious. This preliminary work could lead to the development of more effective antiviral agents than existing treatments that mainly target individual particles.
