An Analysis of 38 Pregnant Women with 2 COVID-19, Their Newborn Infants, and Maternal-Fetal Transmission of SARS-CoV-2: Maternal Coronavirus Infections and Pregnancy Outcomes
Schwartz studied 38 pregnant women with COVID-19 in China to understand the effects of COVID-19 on pregnancy outcomes and found that there were no maternal deaths, no confirmed cases of intrauterine transmission of SARS-CoV-2 from mothers to their fetuses, and all neonatal specimens tested negative for SARS-CoV-2. Schwartz (Mar 17, 2020). An Analysis of 38…

Epidemiology of 2019 Novel Coronavirus Disease-19 in Gansu Province, China, 2020
Fan et al identify the clinical and epidemiologic characteristics that differed significantly during the first and second waves of illness in Gansu Province, which could be helpful in developing more effective local infection control policies and recommendations. Fan et al. (Mar 16, 2020). Epidemiology of 2019 Novel Coronavirus Disease-19 in Gansu Province, China, 2020. Emerg…
Environmental contamination of the SARS-CoV-2 in healthcare premises: An urgent call for protection for healthcare workers
In this investigation of 626 surface samples in hospital in Wuhan, the authors describe the most contaminated zones, objects and personal protection equipment: ICU for novel coronavirus pneumonia (NCP), 31.9%; Obstetric Isolation Ward for pregnant women with NCP, 28.1%; Isolation Ward for NCP, 19.6%; self-service printers, 20%; hand sanitizer dispenser, 20.3%; and gloves, 15.4%. The…

Potential Presymptomatic Transmission of SARS-CoV-2, Zhejiang Province, China, 2020
After investigating a 2-family cluster of persons infected with COVID-19 in Zhejiang Province, China, the authors suggest that infection resulted from contact with a potentially pre-symptomatic traveler from the city of Wuhan. Tong et al. (Mar 9, 2020). Potential Presymptomatic Transmission of SARS-CoV-2, Zhejiang Province, China, 2020. Emerg Infect Dis. https://doi.org/10.3201/eid2605.200198
Indirect Virus Transmission in Cluster of COVID-19 Cases, Wenzhou, China, 2020
The authors investigated a cluster of COVID-19 cases associated with a shopping mall in Wenzhou, China to determine possible modes of virus transmission. The results indicate that indirect transmission potentially occurred via virus contaminated objects, aerosolization in a confined space or spread from asymptomatic infected persons. Cai et al. (Mar 13, 2020). Indirect Virus Transmission…
The time scale of asymptomatic transmission affects estimates of epidemic potential in the COVID-19 outbreak
This study argues for the need to assess both duration and incidence of asymptomatic cases, which can help in evaluating post-pandemic outcomes. Park et al. (Mar 9, 2020).

Epidemiological and clinical characteristics of COVID-19 in adolescents and young adults
A study of 46 hospitalized COVID-19 patients aged 10 to 35 years indicates that adolescents and young adults may have a longer incubation period, a shorter serial interval and may be more likely to be asymptomatic. Liao et al. (Mar 10, 2020). Epidemiological and clinical characteristics of COVID-19 in adolescents and young adults. Pre-print downloaded…
A case report of neonatal COVID-19 infection in China
While most studies in the literature so far have not indicated vertical transmission of COVID-19, this study reports a case of neonatal COVID-19 infection in China 36 hours after birth. Wang et al.

SARS-CoV-2 Infection among Travelers returning from Wuhan, China
In this correspondence based on a follow-up on 94 people who boarded an evacuation flight from Wuhan to Singapore on Jan 30th, the authors highlight the importance of understanding transmission of COVID-19 from asymptomatic people or those with very mild symptoms for successful containment strategies. Ng et al. (Mar 12, 2020). SARS-CoV-2 Infection among Travelers…
Lack of vertical transmission of severe acute respiratory syndrome coronavirus 2, China
This article reiterates that mother-to-child transmission of SARS-CoV-2 is unlikely and highlights the importance of effective implementation of protective measures during delivery. Li et al. (Mar 5, 2020). Lack of vertical transmission of severe acute respiratory syndrome coronavirus 2, China. Emerging Infectious Disease. https://doi.org/10.3201/eid2606.200287
