Viral infections may involve all ocular tissues and may have short and long-term sight-threatening consequences. Among them, ocular infections caused by herpesviruses are the most frequent. HSV-1 keratitis and kerato-uveitis affect approximately are the leading cause of infectious blindness in the Western world, mainly because of corneal opacification caused by recurrences. For this reason, they may warrant long-term antiviral prophylaxis.
Herpes zoster ophthalmicus, accounts for 10 to 20% of all shingles locations and can be associated with severe ocular involvement (keratitis, kerato-uveitis) of which a quarter becomes chronic/recurrent. Post herpetic neuralgias in the trigeminal territory can be particularly debilitating. Necrotizing retinitis caused by herpesviruses (HSV, VZV, CMV) are seldom, but must be considered as absolute visual emergencies, requiring urgent intravenous and intravitreal antiviral treatment.
Clinical pictures depend on the immune status of the host. Adenovirus are the most frequent cause of infectious conjunctivitis. These most often benign infections are highly contagious and may be complicated by visually disabling corneal lesions that may last over months or years. Some arboviruses may be associated with inflammatory ocular manifestations. Among them, congenital Zika infections may cause macular or optic atrophy. Conjunctivitis is frequent during the acute phase of Ebola virus disease.
Up to 15% of survivors present with severe chronic inflammatory ocular conditions caused by viral persistence in uveal tissues. Finally, COVID-19-associated conjunctivitis can precede systemic disease, or even be the unique manifestation of the disease. Utmost caution must be taken because of viral shedding in tears. Pain is a common health problem all around the world. The pain symptoms are various depending on the underlying disease or the direct cause of pain itself. Viral infection could cause arthralgia or acute-onset arthritis, moreover in pandemic era of SARS-CoV-2 detection.
The patients might experience arthritis, arthralgia, joint pain, or musculoskeletal pain. Viral infection including parvovirus B19, hepatitis virus, human immunodeficiency virus, arthropod-borne virus, and coronavirus could cause various types of pain. The pathogenesis of these symptoms is similar to each other despite of different causative organism. This review will discuss about pain caused by various causative organisms.
An Unbiased Approach to Mapping the Signaling Network of the Pseudorabies Virus US3 Protein
The US3 serine/threonine protein kinase is conserved among the alphaherpesvirus family and represents an important virulence factor. US3 plays a role in viral nuclear egress, induces dramatic alterations of the cytoskeleton, represses apoptosis, enhances gene expression and modulates the immune response.
Although several substrates of US3 have been identified, an unbiased screen to identify US3 phosphorylation targets has not yet been described. Here, we perform a shotgun and phosphoproteomics analysis of cells expressing the US3 protein of pseudorabies virus (PRV) to identify US3 phosphorylation targets in an unbiased way. We identified several cellular proteins that are differentially phosphorylated upon US3 expression and validated the phosphorylation of lamin A/C at serine 404, both in US3-transfected and PRV-infected cells.
These results provide new insights into the signaling network of the US3 protein kinase and may serve as a basis for future research into the role of the US3 protein in the viral replication cycle. Pseudocowpox is a zoonosis caused by pseudocowpox virus (PCPV), which mainly affects cows but can be an occupational disease of humans. The aim of the study was to validate a quantitative polymerase chain reaction (qPCR) assay for the detection of PCPV.
The assay was able to detect up to 1000 copies of PCPV per µL in field samples, with a sensitivity of 80% and a specificity of 100%. We did not observe any cross-reactivity between PCPV-positive samples and samples that were positive for other genetically similar viruses. The repeatability and reproducibility were adequate according to parameters preestablished in official test validation manuals.[Ocular manifestations of viral diseases]
Portable Rabies Virus Sequencing in Canine Rabies Endemic Countries Using the Oxford Nanopore MinION
As countries with endemic canine rabies progress towards elimination by 2030, it will become necessary to employ techniques to help plan, monitor, and confirm canine rabies elimination. Sequencing can provide critical information to inform control and vaccination strategies by identifying genetically distinct virus variants that may have different host reservoir species or geographic distributions.
However, many rabies testing laboratories lack the resources or expertise for sequencing, especially in remote or rural areas where human rabies deaths are highest. We developed a low-cost, high throughput rabies virus sequencing method using the Oxford Nanopore MinION portable sequencer.

A total of 259 sequences were generated from diverse rabies virus isolates in public health laboratories lacking rabies virus sequencing capacity in Guatemala, India, Kenya, and Vietnam. Phylogenetic analysis provided valuable insight into rabies virus diversity and distribution in these countries and identified a new rabies virus lineage in Kenya, the first published canine rabies virus sequence from Guatemala, evidence of rabies spread across an international border in Vietnam, and importation of a rabid dog into a state working to become rabies-free in India. Taken together, our evaluation highlights the MinION’s potential for low-cost, high volume sequencing of pathogens in locations with limited resources.
