Close interaction between avian influenza (AI) viruses and humans in Egypt appears to have resulted in many of the worldwide cases of human infections by both H5N1 and H9N2 AI viruses.
There has been substantial MERS-CoV research since 2012, but significant knowledge gaps persist, especially in epidemiology and natural history of the infection. There have been few rigorous studies of baseline prevalence, transmission, and spectrum of disease.
An international study provides a new model to help identify and understand superspreaders and other forms of extreme competence, including less studied "superdiluters" that may protect individuals against infection risk.
Researchers surveilled camels in Egypt, Tunisia, and Senegal to include other domestic mammalian species in contact with infected camels.
The results of this study change our understanding of Japanese encephalitis virus (JEV) transmission in densely populated regions and may help to explain JEV outbreaks without the presence of arthropod vectors.
Ebola virus can persist in immunologically protected body sites in survivors of Ebola virus disease, creating the potential to initiate new chains of transmission.
Ross River virus is Australia’s most common mosquito-borne disease. It infects around 4,000 people a year.
Highly pathogenic avian influenza A(H5N8) clade 188.8.131.52 spread in France during 2016–2017. Researchers assessed the biosecurity and avian influenza virus infection status of 70 backyard flocks near H5N8-infected commercial farms. Backyard flocks linked to commercial farms had elevated risk for H5 infection.
Humans act as a main driver of disease transmission, responsible for African swine fever virus introduction to domestic pig farms and long-distance transmission jumps. By transporting contaminated meat and discarding meat products so that they end up as waste or kitchen leftovers in pig stables or in nature inhabited by wild boar.
The virus that causes severe fever with thrombocytopenia syndrome (SFTS) may have been transmitted person-to-person via aerosols at a hospital in South Korea, indicating that airborne precautions should be added to standard precautions to prevent nosocomial spread of the virus, researchers say.
