The researchers used the dengue sur Dengue cases veillance data published by the Malaysian Ministry of Health during the 3 phases of MCO (which ranged between COVID-19 17th March 2020 and 28th April 2020) was used for determining the cumulative number of dengue patients. GIS Thereafter, the dengue cases were mapped using the Geographical Information System (GIS). The results indi Malaysia cated that during the 42 days of MCO in Peninsular Malaysia, 11,242 total cases of dengue were reported. The daily trend of the dengue cases showed a decrease from 7268 cases that occurred before the MCOs to 4662 dengue cases that occurred during the initial 14 days of the COVID-19 pandemic (i.e., MCO I), to 3075 cases occurring during the MCO II and 3505 dengue cases noted during MCO III. The central peninsular region showed a maximal decrease in new dengue cases (52.62%), followed by the northern peninsular region (1.89%); eastern coastal region (1.25%) and the southern peninsular region (1.14%) during the initial MCO implementation. However, an increase in the new dengue cases was noted during the MCO III period, wherein all states showed an increase in the new dengue cases as compared during MCO II. The decrease in the pattern was not solely based on the MCO, hence, further investigation is necessary after considering different influencing factors. These results have important implication for future large-scale risk assessment, planning and hazard mitigation on dengue management. 1. Introduction eventually renamed SARS-CoV-2 [16].

The visualization of the 91 districts in Peninsular Malaysia. For reporting purposes, this map was divided into fivemain regions namely (i) Northern Region (Perlis, Kedah, Penang, Perak), (ii) East Coast Region (Kelantan, Terengganu, Pahang), (iii) Central Region (Selangor, Kuala Lumpur, Putrajaya) (iv) West region (Negeri Sembilan & Malacca) and (v) Southern Region (i.e. Johor). soon made their way to other Asian countries (including Japan, (ii) Make it mandatory to examine the health status of every individual Thailand, Singapore and Malaysia), Australia, Europe and North arriving in the country; (iii) Restrict the operating hours of essential America [23].

This Malaysian MCO was based on a similar initiative particularly during the month of March, 2020. This alarming disclosure implemented by other countries like China, UK, India, Italy, Spain, led to the Malaysian government’s introduction of several counter France, etc., which restricted the movement of people. Following the measures. These included the installing of an inspection system to implementation of the MCO included a few vital courses of action; 1) a quickly diagnose infected individuals, the carrying out of instantaneous full movement prohibition and broad national meetings, 2) Full re case isolation and thorough tracking, and the quarantining of those striction of all Malaysian travel abroad; 14 days quarantine is required verified to have been in close contact with individuals diagnosed posi for returnees abroad, 3) Full limitation of the entry to the country for tive.

This MCO was based on the Police Act 1967 and the Prevention and Vector control and management, community participation, and Control of Infectious Disease Act (PCID Act 1988) [20]. The MCO I was enforcement are the main components, of the three-pronged dengue implemented in the country between 18th and 30th March 2020. This control strategy employed by the Malaysian government. Vector control MCO was primarily implemented for controlling and decreasing the mostly entails the extensive use of insecticides, to diminish the mosquito spread of COVID-19 in Malaysia, since a sudden spike was noted in the population, in areas where positive cases have been detected. The space reported cases due to several Islamic religious gatherings, consisting of spray application of insecticides (particularly pyrethroids) is executed in 12,000 people, which took place in Sri Petaling, Kuala Lumpur, between the cold or thermal fogging mode (ref.).
