Due to the COVID-19 pandemic, many countries have implemented movement control orders (MCO). Globally, including in Malaysia, such bans have reduced pollution. Thus, this study used remote sensing to examine the particle dispersion and intensity of PM10. Unlike previous research, this technique used Landsat 8 Operational Land Imager (OLI) satellite images to estimate anthropogenic level changes within the study area. Eight models are used to estimate PM10 levels. The models work well because they were developed and tested in India, which has a similar climate to Malaysia. Two models returned results that matched the study area's CAQMs station. Between 10th March 2020 and 26th March 2020 the CAQMS showed an average PM10 concentration of 17-32 g/m3. The pixel based PM10 estimation is 30-35% off in g/m3. However, the percent reduction of PM10 before and during MCO was within 2% of Model 5 and 7. Incorporating geospatial technology into baseline studies to assess current air quality is clearly beneficial. Since the first MCO in March 2020, toxic pollution emissions have decreased significantly. © 2022, Prince of Songkla University. All rights reserved.

The World Health Organization (WHO) declared the 2019-20 coronavirus disease (COVID-19) outbreak a pandemic on 11th of March 2020. The Ministry of Health, Malaysia has made preparations for the involvement of all government hospitals, including some teaching hospitals. This report elaborates and discusses the early establishment of the Hospital Canselor Tuanku Muhriz Crisis Preparedness and Response Centre (HCTM CPRC), highlighting how teaching hospitals function in handling the clinical and epidemiological management of COVID-19 among hospital staff. The setting comprises of four critical functions of the HCTM CPRC, namely case investigation, close contact tracing, surveillance for data reporting and risk communication. This report highlighted that a CPRC in teaching hospitals benefits not only the patients and the hospital administration but also all hospital staff, especially in managing COVID-19 pandemic emergency crisis. © 2021 Penerbit Universiti Kebangsaan Malaysia.
