Information on COVID-19

Information on COVID-19 for medical personnel in radiology department
JRS Data Repository for Surveillance of Virus Pneumonia in Japan
Japan Radiological Society (JRS) has started surveillance on diagnostic imaging of virus pneumonia in order to grasp the novel coronavirus clusters and the spread of the virus infection in Japan.
JRS has provided this information sequentially to the governmental strategy team, and to the surveillance section and the viral cluster section in the Ministry of Health, Labor and Welfare.
Number of infected people is still increasing, and there is a possibility of outbreak anywhere at any time in Japan.
On this surveillance, data are voluntarily collected from radiologists and its accuracy is only guaranteed when data are registered correctly.
Results will be largely reflected in future governmental and prefectural strategies against the virus, so we would appreciate if you could actively provide information.

Implementing Singapore model of segregation
<Summary>
A tertiary hospital in Singapore shares its experience of handling the work during the outbreaks of infectious diseases, namely during the severe acute respiratory syndrome (SARS) and the coronavirus disease (COVID-19) epidemics. Focusing on the operations of the radiology department, it offers recommendations that may be useful for other hospital units too.

COVID-19 pneumonia: infection control protocol inside computed tomography suites
https://link.springer.com/article/10.1007/s11604-020-00948-y
<Summary>
A novel coronavirus (severe acute respiratory syndrome coronavirus 2) causes a cluster of pneumonia cases in Wuhan, China. It spread rapidly and globally. CT imaging is helpful for the evaluation of the novel coronavirus disease 2019 (COVID-19) pneumonia. Infection control inside the CT suites is also important to prevent hospital-related transmission of COVID-19. We present our experience with infection control protocol for COVID-19 inside the CT suites.
A novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was identified as the etiology for a cluster of pneumonia cases in Wuhan, a city in the Hubei Province of China. It spread rapidly throughout China, resulting in a nation-wide epidemic; moreover, there were reports of sporadic cases globally. Previously published reports describe the imaging features of patients with the novel coronavirus disease 2019 (COVID-19) pneumonia. These reports have highlighted the clinical importance of chest computed tomography (CT) for the detection and management of patients infected with SARS-CoV-2. On the other hand, the infection control in the CT suite is also critically important because high rate of presumed hospital-related transmission of COVID-19 (41.3%) was reported. Radiologists should not only be aware of the CT features of patients with COVID-19 pneumonia but they must also be well informed of the infection control protocols to be followed inside the CT suite to prevent the spread of infection. Herein, we present our experience with infection control protocol for COVID-19 inside the CT suite.
Chest CT Findings in Cases from the Cruise Ship “Diamond Princess” with Coronavirus Disease 2019 (COVID-19)
https://pubs.rsna.org/doi/10.1148/ryct.2020200110
<Summary>- Of 104 cases analyzed, 76 (73%) were asymptomatic, 41 (54%) of which had pneumonic changes on CT. Other 28 (27%) cases were symptomatic, 22 (79%) of which had abnormal CT findings.
- Asymptomatic cases showed more GGO predominance over consolidation (83%), while symptomatic cases were more likely to show a consolidation predominance over GGO (41%).
- Asymptomatic cases showed milder CT severity score than symptomatic cases

<Summary>
As of April 7 in 2020, a total of 55,311 people in Japan underwent polymerase chain reaction (PCR) tests for coronavirus (COVID-19), of which 48,357 were for patients within the country. As of the same day, a total of 3,906 cases were confirmed positive with the virus. According to the source, number of PCR tests conducted in the national institute of infectious diseases and local institutes of health in the country amounted to 82,465 cases as of April 5.
