Effectiveness of Physical Distancing: Staying 6 Feet Over to Put Respiratory Viruses 6 Feet Under.
Community transmission of severe acute respiratory illness Coronavirus-2 (SARS-CoV-2) in Arizona was noted in March 2020. It was our hypothesis that the associated implementation of physical distancing and masking led to a decline in circulation and detection of common respiratory viruses. Nasopharyngeal swabs processed with the Biofire, Film Array respiratory panel at Mayo Clinic Arizona were reviewed from January 1, 2017, to July 31, 2020. ⋯ Positivity for a second virus occurred in a mean of 2.1 positive tests (3.3%) in Period A but was absent in Period B. Implementation of distancing and masking coincides with a marked reduction in respiratory virus detection and likely circulation. Data from the fall/winter of 2020 will help clarify the potential role for distancing and masking as a mitigation strategy, not only for SARS-CoV-2 but also in the seasonal battle against common respiratory viruses.

Observational Study
SARS-CoV-2 infection causes pulmonary shunt by vasodilatation.
Patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may present a significant hypoxemia. The exactly mechanism of such hypoxemia in patients with coronavirus disease 2019 (COVID-19) is not well described. It has been suggested that microthrombosis contributes to this mechanism, increasing pulmonary dead space. ⋯ Ten patients were recruited; one patient was excluded due to low quality of echocardiographic image, and nine patients were included. IPVD was found in seven (78%) patients, with different grades, including patient with normal compliance and the one without invasive ventilation. We demonstrated that shunt by IPVD is present among patients with COVID-19, and this mechanism is probably implicated in significant hypoxemia observed.

CT chest analysis of 2019 novel coronavirus pneumonia: An Indian perspective.
Since its outbreak, the COVID-19 pneumonia pandemic is rapidly spreading across India; although computed tomography of chest (CT chest) is not recommended as a screening tool, there is a rapid surge in the CT chest performed in suspected cases. We should be aware of the imaging features among the Indian population. ⋯ COVID-19 pneumonia showed multifocal predominantly subpleural basal posteriorly located GGOs and/or consolidations which were predominantly well defined. "Crazy paving" was prevailing in the intermediate stage while early traction bronchiectasis among the patients presented later in the course of illness.

Since the outbreak of severe acute respiratory coronavirus 2 (SARS-CoV-2), the coronavirus disease 2019 has had a wide range of effects on human health. This paper summarizes the data related to the effects of the SARS-CoV-2 infection on human reproduction. Both the male and female reproductive tract express high levels of receptors and proteins needed for viral cell entry. ⋯ Those who are symptomatic for SARS-CoV-2 are more likely to have increased rates of prematurity and intrapartum fetal distress than those who are asymptomatic. Vertical transmission cannot be completely ruled out, but neonatal infection rates are low. Vaccination appears to be safe and is indicated for use in pregnant and lactating women because the benefits outweigh the risks.

Case ReportsCOVID-19 Presenting with Spontaneous Pneumothorax.
The coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The disease mainly affects respiratory system. Its common clinical findings include fever, cough and shortness of breath. ⋯ COVID-19 was diagnosed on testing of nasopharyngeal swab. In conclusion, spontaneous pneumothorax is one of the rare presentations of COVID-19 pneumonia and should be kept in mind in patients presenting with shortness of breath and chest pain. Key Words: Spontaneous pneumothorax, Corona, pneumonia.
