Whether ethnicity is an independent risk factor for severe Covid-19 disease is unclear.PurposeReview the association between ethnicity and poor outcomes including all-cause mortality, hospitalisation, critical care admission, respiratory and kidney failure.Data SourcesMEDLINE, EMBASE, Cochrane COVID-19 Study Register, WHO COVID-19 Global Research Database up to 15/06/2020, and preprint servers.

This is due to an uneven increase in vehicle vehicles to road infrastructure. The p ea k o f traffic jam at Intersection o f Junction often occurs at 16.00-17.30 WIB. The problem at this junction is the amount o f time delay and the length o f the queue. One way to reduce congestion problems at the Intersection is to construct road infrastructure, one underpass. Based on these problems, research on the effect o f underpass application on congestion parameters at several other intersections adjacent to the intersection o f Kentungan. This research is a M ulti Channel M ulti Phase model configuration, by creating an underpass model o f the Autodesk Infraworks 360 software. Before modeling underpass conditions, it is done in advance o f the existing model o f Intersection o f Kentungan. The data inputted to this existing model is the total data o f vehicles crossing the intersection o f Kentungan fo r one hour. Verification model in this research is done by visual testing and check the duration o f green light at the time o f simulation done. Validation in this research is done by using hypothesis test, paired t-test. Then the parameters fo r validation are data ie the average waiting time o f the vehicle, the maximum queue length and the number o f vehicles passing through the green light in one cycle.In this study using two scenarios, in scenario 1 is the underpass model with the condition o f the intersection and the scenario 2 is the underpass model with the roundabout condition. The results obtained from both scenarios are compared with the existing model results. The compared parameters are the average vehicle delay time and maximum queue length on each approach. It is expected from the comparison analysis to show that the Kentungan Intersection after the built underpass has decreased significantly on the average delay time and maximum queue length.
