The Transmission of SARS-CoV-2 Infection on the Ocular Surface and Prevention Strategies.

Cells 2021 04 2;10(4). Epub 2021 Apr 2.

Department of Ophthalmology, Kyoto Prefectural University of Medicine, Kyoto 6020841, Japan.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a global health problem. Although the respiratory system is the main impaired organ, conjunctivitis is one of its common findings. However, it is not yet understood if SARS-CoV-2 can infect the eye and if the ocular surface can be a potential route of SARS-CoV-2 transmissions. Read More

Molecular Characterization of Coxsackievirus A24v from Feces and Conjunctiva Reveals Epidemiological Links.

Microorganisms 2021 Mar 5;9(3). Epub 2021 Mar 5.

Immunovirology Unit, Department of Clinical Sciences, Skåne University Hospital, Lund University, 22185 Malmo, Sweden.

Coxsackievirus A24 variant (CVA24v), the main causative agent of acute hemorrhagic conjunctivitis (AHC), can be isolated from both the eyes and lower alimentary tract. However, the molecular features of CVA24v in feces is not well-documented. In this study, we compared the VP1 and 3C sequences of CVA24v strains isolated from feces during AHC epidemics in Cuba in 1997, 2003, and 2008-2009 with those obtained from conjunctival swabs during the same epidemic period.

Quantitative investigation of viral load in acute to subacute human adenovirus type 54 conjunctivitis.

Jpn J Infect Dis 2021 Mar 31. Epub 2021 Mar 31.

Division of Ophthalmology and Visual Science, Faculty of Medicine, Tottori University, Japan.

To understand the clinical course of human adenoviral (HAdV) conjunctivitis for establishing a better treatment regimen, thirty-eight eyes of 19 patients with HAdV-54 conjunctivitis for less than one week from onset were evaluated for clinical signs and symptoms and DNA copy numbers. It is observed that a viral load of 10-10 is required to develop symptoms of HAdV conjunctivitis, as symptoms were present in all the eyes whose viral load was ≥10 at least once during the course. Next, it is observed that asymptomatic infections in contralateral eyes are common as the virus was detected in most eyes that did not develop conjunctivitis. Read More

[COVID-19 in children: SARS-CoV-2-related inflammatory multisystem syndrome mimicking Kawasaki disease].

Bull Acad Natl Med 2021 Mar 18. Epub 2021 Mar 18.

PHC, Service des Urgences pédiatriques, Hôpital Robert Debré, Assistance Publique-Hôpitaux de Paris.

SARS-CoV-2 pandemics is characterized by a high level of infectivity and a high mortality among adults at risk (older than 65 years, obesity, diabetes, systemic hypertension). Following a common viral pneumonia, a multisystem inflammatory syndrome sometimes occurs, including an Acute Respiratory Distress Syndrome (ARDS) carrying a high mortality. Unlike most common respiratory viruses, children seem less susceptible to SARS-CoV-2 infection and generally develop a mild disease with low mortality. Read More

Povidone iodine for the treatment of adenoviral conjunctivitis.

Clin Exp Optom 2021 Apr 11;104(3):308-314. Epub 2021 Feb 11.

School of Optometry and Vision Science, The University of New South Wales, Sydney, Australia.

Adenoviral conjunctivitis is the most common cause of ocular viral infection in the world, but currently has no approved therapeutic treatments. The antiseptic povidone-iodine (PVP-I) has been used as an off-label treatment for the condition, but high-quality evidence for its use is limited. This paper aims to review the literature surrounding the use of PVP-I in the management of adenoviral conjunctivitis. Read More

Adenovirus and the Cornea: More Than Meets the Eye.

Viruses 2021 02 13;13(2). Epub 2021 Feb 13.

Massachusetts Eye and Ear, Harvard Medical School, 243 Charles Street, Boston, MA 02114, USA.

Human adenoviruses cause disease at multiple mucosal sites, including the respiratory, gastrointestinal, and genitourinary tracts, and are common agents of conjunctivitis. One site of infection that has received sparse attention is the cornea, a transparent tissue and the window of the eye. While most adenovirus infections are self-limited, corneal inflammation (keratitis) due to adenovirus can persist or recur for months to years after infection, leading to reduced vision, discomfort, and light sensitivity.

Whole-genome analysis to describe a human adenovirus D8 conjunctivitis outbreak in a tertiary hospital.

J Med Virol 2021 Feb 5. Epub 2021 Feb 5.

Department of Microbiology, Hospital de la Santa Creu i Sant Pau, Institut d'Investigació Biomèdica Sant Pau, Barcelona, Spain.

Conjunctivitis is a frequent ocular disorder caused by human adenoviruses (HAdVs). Only a few of the 45 HAdV-D species are associated with epidemic keratoconjunctivitis, including HAdV-D8. Nosocomial outbreaks due to HAdV-D8 have been rarely described, because keratoconjunctivitis cases are clinically diagnosed and treated without having to characterize the causative agent. Read More

Intensive ocular sampling for the detection of subclinical canine herpesvirus-1 shedding in dogs with experimentally-induced latent infection.

Vet Microbiol 2021 Mar 27;254:109001. Epub 2021 Jan 27.

Department of Population Medicine and Diagnostic Sciences, College of Veterinary Medicine, Cornell University, Ithaca, NY, 14853, USA.

Latent canine herpesvirus-1 (CaHV-1) infections are common in domestic dogs, but viral shedding patterns in dogs are poorly understood. Previous research failed to detect spontaneous subclinical ocular CaHV-1 shedding in dogs following ocular infection, a situation that is fundamentally distinct from many of the alphaherpesviruses closely related to CaHV-1. One possible explanation for this finding is that the sampling interval in the prior studies evaluating ocular shedding patterns was too infrequent to detect rapidly cleared, brief ocular viral shedding episodes.

The Ocular Manifestations of COVID-19 Through Conjunctivitis.

Cureus 2020 Dec 22;12(12):e12218. Epub 2020 Dec 22.

Research, Mayo Clinic, Jacksonville, USA.

There is growing evidence that the novel coronavirus (SARS-CoV-2) is capable of transmission through the eye. Research suggests that infection by SARS-CoV-2 can produce an inflammation of the conjunctiva, which leads to redness and itchiness of the eyes. Furthermore, viral particles have been detected in conjunctival secretions of SARS-CoV-2 patients who present with conjunctivitis and is likely another mode of transmission. Read More

Cohort profile: Study on Zika virus infection in Brazil (ZIKABRA study).

PLoS One 2021 5;16(1):e0244981. Epub 2021 Jan 5.

Department of Sexual and Reproductive Health and Research, World Health Organization, Geneva, Switzerland.

Zika virus (ZIKV) has been detected in blood, urine, semen, cerebral spinal fluid, saliva, amniotic fluid, and breast milk. In most ZIKV infected individuals, the virus is detected in the blood to one week after the onset of symptoms and has been found to persist longer in urine and semen. To better understand virus dynamics, a prospective cohort study was conducted in Brazil to assess the presence and duration of ZIKV and related markers (viral RNA, antibodies, T cell response, and innate immunity) in blood, semen, saliva, urine, vaginal secretions/menstrual blood, rectal swab and sweat.

Ophthalmic manifestations of COVID-19; a less-appreciated yet significant challenge.

Int Ophthalmol 2021 Mar 2;41(3):1141-1147. Epub 2021 Jan 2.

Department of Neuroscience, School of Advanced Medical Sciences and Technologies, Shiraz University of Medical Sciences, Shiraz, Iran.

Aim: The current world has changed in all shapes since the emergence of the novel coronavirus (nCoV-2) also known as COVID-19. Among the extra-pulmonary manifestations of nCoV-2, ophthalmic symptoms have less been systematically studied. The so far existing body of evidence indicates that nCoV-2 has the potential to affect both anterior and posterior chambers of the eye. Read More
