Background: Ensuring consistent adherence to antiretroviral therapy (ART) is crucial for effective HIV treatment and achieving viral suppression. Within prisons, the prevalence of HIV is notably high, and incarcerated individuals face an increased risk of transmitting the virus both during and after incarceration. However, facilitators and barriers to ART adherence among these individuals in low- and middle-income countries remain inadequately explored.

The Zika virus (ZIKV) epidemic elicited a rapid commitment to the development of animal models for ZIKV research. Non-human primates (NHPs) and mice have made significant contributions to this research, but NHPs are expensive, have a long gestation period, and are available only in small numbers; non-genetically modified mice are resistant to infection. To address these deficiencies, we have established the laboratory opossum, , as a small animal model that complements the mouse and monkey models.

The hepatitis B virus (HBV) infects approximately 290 million people globally, with chronic infection sustained by persistent viral gene expression. Recent single-cell analyses of HBV viral transcripts have uncovered novel features of HBV transcription and provided fresh insights into its regulation at the single-cell level. In this review, we summarize the latest advancements in understanding HBV viral transcription in individual hepatocytes and highlight emerging technologies that hold promise for future research.

Porcine reproductive and respiratory syndrome (PRRS), characterized by reproductive failures in breeding pigs and respiratory diseases in growing pigs, is a widespread and challenging disease. The agent, PRRSV, is a single-strand RNA virus that is undergoing continuous mutation and evolution, resulting in the global spread of multiple strains with different genetic characteristics and variable antigens. There are currently no effective measures to eradicate PRRS, and vaccination is crucial for controlling the disease.

Objectives: Although bluetongue is not a contagious disease, it is easily transmitted and spread by appropriate insect vectors, causing great economic damage. Climate change has led to the fact that vectors and diseases have spread to the top of Northern Europe, causing great economic losses in livestock production. An even greater problem is controlling the disease, because numerous species of domestic and wild ruminants are susceptible to bluetongue.
