The high respiratory viruses' detection rate and availability of results within two hours when using FilmArray-RP were associated with decreases in antibiotic prescriptions and complementary studies and more accurate use of oseltamivir.
The COVID-19 pandemic has forced all nations to take an active role in infection control incorporating recommendations and measures to control viral dissemination. The epidemiological impact is very diverse and dynamic, even within the same region. Scientific knowledge regarding SARS-CoV-2 continues to improve every day with protocols needing to be updated and adjusted on a regular basis. Ophthalmology is a medical specialty identified to be at high risk for several reasons: it has very close doctor-patient contact, the virus has been detected in tears, and the ocular surface serves as a gateway to developing the infection. We have reviewed the current information on SARS-CoV-2 in the ophthalmologic field and provide up-to-date recommendations to help create protocols that can adapt to the dynamic situation of ophthalmologic institutions, patient cases, economic situations and access to diagnostic tests. This paper outlines the main recommendations regarding the initial consultation and outpatient clinics, measures to apply in the operating room (OR), and suggestions for post-surgical controls. Triage, according to the patient's conditions and eye pathology, reduction of the time the patient is at the institution, social distancing, correct use of personal protective equipment (PPE), barrier methods, hygiene, as well as other recommendations mentioned in this document, will allow physicians to take care of the visual health of the patients while reducing the impact of the COVID-19 pandemic.
To determine clinical and virologic characteristics of pandemic (H1N1) 2009 in Buenos Aires, Argentina, we conducted real-time reverse transcription–PCR on samples from patients with influenza-like illness, June 11–30, 2009. Of 513 patients tested, 54% were positive for influenza virus subtype H1N1. Infection rate was lowest for patients ≥60 years of age.
Data on the clinical presentation, risk factors, and outcomes for healthcare personnel (HCP) infected with influenza A H1N1 virus (H1N1) are limited. From June to July 2009, a prospective study was conducted among HCP with influenza-like illness (ILI) at university hospitals in Buenos Aires. A reverse transcription polymerase chain reaction (RT-PCR) was used to diagnose H1N1. A logistic regression model was developed to identify factors associated with H1N1. Among 1519 HCP, 96 (6.3%) were diagnosed with an ILI. Of these, 85 (88.5%) were swabbed for H1N1 detection, with 43 positive cases (2.8%). Seasonal influenza immunization was recorded in 76%. Comparison of H1N1-positive vs. H1N1-negative cases showed that H1N1-positive cases more frequently had asthenia (72% vs. 48%, p = 0.03) and cough (79% vs. 43%, p = 0.008) and less frequently had diarrhoea (9% vs. 29%, p = 0.03) and prior prophylaxis with oseltamivir (5% vs. 31%, p = 0.002). The logistic regression model showed that presence of cough (odds ratio (OR) 6.93, 95% confidence interval (CI) 2.24, 21.4) was associated with an increased risk of H1N1. Prior prophylaxis with oseltamivir (OR 0.08, 95% CI 0.01, 0.43) was associated with a lower probability of H1N1 infection. A high proportion of HCP with an ILI were infected with H1N1. Complication rates were relatively low. Prior prophylaxis with oseltamivir was associated with a lower risk of developing H1N1.
El virus de la viruela símica es un orthopoxvirus de características zoonóticas endémico en las regiones de África Central y África Occidental, donde causa brotes desde 1970. En las últimas décadas se registró un aumento exponencial de casos, probablemente asociado a la disminución en la inmunidad conferida por la vacuna antivariólica, discontinuada luego de la erradicación de la viruela. En los últimos años se registraron casos esporádicos fuera del continente africano, siempre relacionados epidemiológicamente a la permanencia en áreas endémicas o contacto con animales infectados. Desde el 13 de mayo de 2022 se encuentra en curso el mayor brote de viruela símica registrado fuera de las áreas endémicas de África, con casos en los cinco continentes. La extensión, el impacto y la duración del brote permanecen aún inciertos.
