Influenza virus is a highly contagious zoonotic respiratory disease that causes seasonal outbreaks each year and unpredictable pandemics occasionally with high morbidity and mortality rates, posing a great threat to public health worldwide. Besides the limited effect of vaccines, the problem is exacerbated by the lack of drugs with strong antiviral activity against all flu strains. Currently, there are two classes of antiviral drugs available that are chemosynthetic and approved against influenza A virus for prophylactic and therapeutic treatment, but the appearance of drug-resistant virus strains is a serious issue that strikes at the core of influenza control. There is therefore an urgent need to develop new antiviral drugs. Many reports have shown that the development of novel bioactive plant extracts and microbial extracts has significant advantages in influenza treatment. This paper comprehensively reviews the development and effects of chemosynthetic drugs, plant extracts, and microbial extracts with influenza antiviral activity, hoping to provide some references for novel antiviral drug design and promising alternative candidates for further anti-influenza drug development.

Hepatitis B virus (HBV) infects cells by attaching to heparan sulfate proteoglycans (HSPG) and Na/taurocholate cotransporting polypeptide (NTCP). The endothelial lipase LIPG bridges HSPG and HBV, facilitating HBV attachment. From a randomized peptide expression library, we identified a short sequence binding to LIPG.

Introduction: Dietary diversity is the utilization of food and food groups consumed by individuals over 24 h, which is an indicator of a diet's micronutrient adequacy. Dietary management in people with HIV patients is the key to sustaining their day-to-day activities and contributing to their lively hood. The level of dietary diversity among HIV-positive patients in Ethiopia shows considerable variation, ranging from 29 to 71.

Background: Direct acting antivirals (DAAs) have demonstrated remarkable efficacy, in achieving hepatitis C viral (HCV) elimination rates higher than 90%. One particular concern associated with treatment failure is the emergence of resistance associated substitutions (RASs) in the genome. The occurrence of RASs highlights the adaptability and resilience of the HCV.

MicroRNAs (miRNAs) are highly conserved endogenous non-coding RNAs that play a crucial role in fish immune response by regulating gene expression at the post-transcriptional level. In recent years, the viral diseases caused by infectious hematopoietic necrosis virus (IHNV) have caused significant economic losses in rainbow trout (Oncorhynchus mykiss) aquaculture, whereas the immune regulatory mechanisms of miRNAs involved in rainbow trout resistance to IHNV infection remains largely undefined. In this study, we analyzed the structural characteristics of Oncorhynchus mykiss tumor necrosis factor receptor-associated factor 3 (OmTRAF3) by bioinformatics software and explored the molecular mechanism of miR-203-3p in rainbow trout resistance to IHNV by regulating OmTRAF3 in vivo and in vitro.

Nucleoside analogs (NAs), as antiviral drugs, play a significant role in clinical medicine, constituting approximately 50 % of all antiviral therapies in current use. Nucleoside inhibitors function by mimicking the structure of natural nucleosides, integrating themselves into viral genetic material during replication, and subsequently inhibiting the virus's ability to reproduce. They are used to treat a variety of viral infections, including herpes simplex, hepatitis B, and acquired immunodeficiency syndrome (AIDS).
