Monkeypox infection is caused by the Orthopoxvirus (OPXV) genus of the Poxviridae family, closely resembling its more famous sibling smallpox. Recently World Health Organization (WHO), have renamed monkeypox as Mpox citing racial concerns, so we will be referring monkeypox as Mpox There has been a recent outbreak in May 2022 when more than 31,800 confirmed and suspected cases of Mpox were identified in all 6 WHO regions. On 23 July 2022, WHO declared it a public health emergency. Prior to the current outbreak, Mpox had been reported in people from several parts of central and west African countries; and almost all Mpox cases in people outside of Africa were linked to international travel to countries where the disease commonly occurs or through imported animals...

To investigate the antigenic changes in parechovirus 1 (PeVA1), seroepidemiological analyses were performed against the Harris strain (Harris), isolated in 1956, and PeVA1/Yamagata.JPN/2021-4785, isolated in 2021, using immune sera and 207 and 237 human serum specimens collected in 2021 and 1976, respectively. Although rabbit immune sera showed the highest neutralization antibody (NT-Ab) titers against the immunized viruses at 1:12800~1:102400, they were cross-reactive at 1:400~1:800. All 62 Yamagata isolates obtained between 2001 and 2021 (Yamagata strains), belonging to phylogenetic lineage 1B, reacted more strongly (mostly 4-64 times) to antiserum against PeVA1/Yamagata...

Yellow fever (YF) virus is a mosquito-borne virus belonging to the Flaviviridae family that circulates in tropical and subtropical areas of Africa and South America. Despite the availability of an effective vaccine, YF remains a threat to travelers, residents of endemic areas, and unvaccinated populations. YF vaccination and natural infection both induce the production of neutralizing antibodies. Serological diagnostic methods detecting YF virus-specific antibodies demonstrate high levels of cross-reactivities with other flaviviruses...

The current COVID-19 vaccination program requires frequent booster vaccination to maintain sufficient neutralization levels against immune evasive SARS-CoV-2 variants. However, prior studies found more potent and durable immune response in convalescing individuals, raising the possibility of less frequent booster vaccination for them. Here, we conducted a longitudinal immunological study based on two prospective cohorts of booster vaccinated convalescing COVID-19 patients or healthcare workers (HCW) without COVID-19 history in Xiangyang, China...

Cancer management is major concern of health organizations and viral cancers account for approximately 15.4% of all known human cancers. Due to large number of patients, efficient treatments for viral cancers are needed. De novo drug discovery is time consuming and expensive process with high failure rate in clinical stages. To address this problem and provide treatments to patients suffering from viral cancers faster, drug repurposing emerges as an effective alternative which aims to find the other indications of the FDA approved drugs...

Viral metagenomics has been extensively applied for the identification of emerging or poorly characterized viruses. In this study, we applied metagenomics for the identification of viral infections among pediatric patients with acute respiratory disease but who tested negative for SARS-CoV-2. Twelve pools composed of 8 nasopharyngeal specimens were submitted to viral metagenomics. Surprisingly, in two of the pools, we identified reads belonging to the poorly characterized Malawi polyomavirus (MWPyV). Then, the samples composing the positive pools were individually tested using qPCR for identification of the MWPyV index cases...

Measles virus (MeV) has been an excellent vector platform for delivering vaccines against many pathogens because of its high safety and efficacy, and induction of long-lived immunity. Early in the COVID-19 pandemic, a recombinant MeV (rMeV) expressing the prefusion full-length spike protein stabilized by two prolines (TMV-083) was developed and tested in phase 1 and 1/2 clinical trials but was discontinued because of insufficient immunogenicity and a low seroconversion rate in adults. Here, we compared the immunogenicity of rMeV expressing a soluble prefusion spike (preS) protein stabilized by two prolines (rMeV-preS-2P) with a rMeV expressing a soluble preS protein stabilized by six prolines (rMeV-preS-6P)...

Recent findings in permanent cell lines suggested that SARS-CoV-2 Omicron BA.1 induces a stronger interferon response than Delta. Here, we show that BA.1 and BA.5 but not Delta induce an antiviral state in air-liquid interface (ALI) cultures of primary human bronchial epithelial (HBE) cells and primary human monocytes. Both Omicron subvariants caused the production of biologically active type I (α/β) and III (λ) interferons and protected cells from super-infection with influenza A viruses...

BACKGROUND: Statins may protect against adverse outcomes from Coronavirus disease 2019 (COVID-19) through their pleiotropic effects. Endothelial dysfunction seems to be implicated in the pathophysiology of COVID-19, and can be attenuated by statins. This study assessed the role of preadmission statin therapy and its interaction with endothelial function, measured using flow-mediated dilation (FMD) at hospital admission, in predicting in-hospital outcomes among patients with COVID-19 having high-to-very high cardiovascular risk...
