Patricia Aguilar, PhD, assistant professor of Pathology, has found that a recently discovered virus is able to spread to healthy neighboring cells by a mechanism previously unseen in other arthropod-borne viruses. Severe fever with thrombocytopenia syndrome (SFTS) virus, a tick-borne bunyavirus discovered in China that causes severe fever and can lead to death, was first described by a team of scientists, including UTMB experts, in 2011.
