Background: Testing for SARS-CoV-2 using polymerase chain reaction (PCR) and SARS-CoV-2 antibody tests is a significant part of the effort to combat the COVID-19 pandemic. Mass testing of healthy individuals raises several issues, however, and the results can be challenging to interpret.
Case Presentation: A healthy 19-year-old man entered the military after two weeks of quarantine. The recruit had no respiratory symptoms or fever before, during or after his enrolment, and no history of SARS-CoV-2 exposure. At enrolment, he had a positive rapid test and a venous blood sample showed antibodies against SARS-CoV-2. PCR tests of specimens obtained from the upper respiratory tract were negative at enrolment and at week three, but were positive at week six.
Interpretation: The overall assessment of all the tests indicates a probable asymptomatic infection. This case report illustrates the challenge of interpreting screening results in asymptomatic individuals.

Background: Public health is seriously threatened by transmission of zoonotic infection through the food chain. Factors like increasing population, deforestation, high demand for animal protein, and trade of sub-clinically infected animals are the main causes of the spread of infections from asymptomatic animals to humans. Despite several national programs like (The Clean India Mission) prevention of open defecation and water, sanitation, and hygiene (WASH), the incidence of diarrhoeal diseases remains high in India.

Middle East respiratory syndrome coronavirus (MERS-CoV) is an important zoonotic pathogen. The aim of this paper is to report one polymerase chain reaction (PCR)-positive case of MERS-CoV in a 27-year-old man who was involved in a nationwide longitudinal surveillance study of certain zoonotic diseases in Jordan including MERS-CoV. Whole-blood and nasal swab samples were collected from the man and five camels in the vicinity of his living area.

Severe Acute Respiratory Syndrome-Related Coronavirus 2 (SARS-CoV-2) infection during pregnancy was associated with a number of adverse pregnancy outcomes, including miscarriage, preeclampsia, preterm birth, and stillbirth. The virus persistence can last for a long time, and the consequences of a previous coronavirus infection are currently under study. This study aimed to establish the clinical features of the course of pregnancy and childbirth in women with a history of asymptomatic coronavirus disease 2019 (COVID-19).

The scientific evidence supporting recommendations for dietary supplement use to prevent or treat coronavirus disease 2019 (COVID‑19) is not well‑established. This cohort study investigates the relationship between dietary supplement usage and COVID‑19 symptoms among 27,181 adults tested for COVID‑19. Using data from surveys following COVID‑19 testing, conducted by the University of Arkansas for Medical Sciences, associations between dietary supplement usage, symptomatology, and COVID‑19 status were explored.

Unlabelled: Testing for the causative agent of coronavirus disease 2019 (COVID-19), severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has been crucial in tracking disease spread and informing public health decisions. Wastewater-based epidemiology has helped to alleviate some of the strain of testing through broader, population-level surveillance, and has been applied widely on college campuses. However, questions remain about the impact of various sampling methods, target types, environmental factors, and infrastructure variables on SARS-CoV-2 detection.
