METHODS: This is a single-center, cross-sectional study using in-patient data maintained by the Case-Mix Unit of a teaching hospital in Malaysia from 2016 to 2017. The study included all patients with International Classification of Disease (ICD) code 164 (stroke, not specified as hemorrhage or infarct). The significance of association was determined using nonparametric tests in the form of the Mann-Whitney U test and the Kruskal-Wallis test.

RESULTS: A total of 162 stroke patients from 2016 to 2017 from Case-Mix database were included in the study. The age ranged from 31 to 97 years old. The minimum and maximum LOS for patients with stroke ranged from 1 to 17 days. The severity of illness was found to be significantly associated with longer LOS (p < 0.001); however, age, sex, and presence of co-morbidities did not show any significant association.

METHODS: All laboratory-confirmed COVID-19 cases reported to the Petaling District Health Office between 1 February and 26 June 2020 were analysed. Socio-demographic characteristics, symptoms, date of onset, date of exposure, travel history and history of comorbidities were obtained by phone interviews using one of two investigation forms. The descriptive analysis was conducted according to time, place and person.

RESULTS: There were 437 COVID-19 cases, for an incidence rate of 24/100 000 population. Ten (2.3%) deaths and 427 recovered cases were recorded. Of the 437 cases, 35.5% remained asymptomatic and 64.5% were symptomatic. Common symptoms included fever (43.8%), cough (31.6%) and sore throat (16.2%); 67.3% had no comorbidities, 62.5% reported close contact with a confirmed case, and 76.7% were local infections. Transmission occurred in four main groups: religious gatherings (20.4%), corporations (15.1%), health facilities (10.3%) and a wholesale wet market (6.4%). In 31.9% of confirmed cases, an epidemiological link to an asymptomatic case was found.
