The role of respiratory viruses in community-acquired pneumonia (CAP) in human immunodeficiency virus (HIV)-infected patients has not been extensively investigated. The objective was to study the implication of respiratory viruses in HIV patients with CAP, through a prospective, three-year study in a third-level hospital. Respiratory viruses were implicated in 14 of the 67 cases of CAP diagnosed and were the only microorganism isolated in 8 of them. Evolution of the disease was similar in patients with CAP associated with respiratory virus infection and those with CAP alone. Respiratory virus infection in HIV-infected patients with CAP is not associated with a poorer prognosis.

Equid alphaherpesvirus 4 (EqAHV4; , ; equine rhinopneumonitis virus) has seldom been associated with complications such as abortion and myeloencephalopathy, given the low tendency of this virus to induce viremia. We investigated the frequency of EqAHV4 viremia in horses with fever and respiratory signs. Case selection included all equids with EqAHV4 quantitative real-time PCR (qPCR)-positive nasal secretions (defined as EqAHV4 qPCR-positive cases) submitted to a diagnostic laboratory.

Porcine reproductive and respiratory syndrome virus (PRRSV) is one of the most harmful pathogens in the swine industry. Our previous studies demonstrated that the small extracellular domain (ECL2) of CLDN4 effectively blocks PRRSV infection. In this study, we explored the in vivo administration of swine ECL2 (sECL2) and found that it blocked HP-PRRSV infection and alleviated histopathological changes in organs.

The coronavirus disease 2019 (COVID-19) epidemic has brought major challenges to the global health system, and influenza is also a problem that cannot be ignored. We aimed to explore and compare the clinical characteristics of COVID-19 and influenza to deepen the understanding of these two diseases and provide some guidance for clinicians to make differential diagnoses. We searched PubMed, Embase and Web of Science for articles and performed a meta-analysis using Stata 14.
