This paper attempts to ascertain the impacts of population density on the spread and severity of COVID-19 in Malaysia. Besides describing the spatio-temporal contagion risk of the virus, ultimately, it seeks to test the hypothesis that higher population density results in exacerbated COVID-19 virulence in the community. The population density of 143 districts in Malaysia, as per data from Malaysia’s 2010 population census, was plotted against cumulative COVID-19 cases and infection rates of COVID-19 cases, which were obtained from Malaysia’s Ministry of Health official website. The data of these three variables were collected between 19 January 2020 and 31 December 2020. Based on the observations, districts that have high population densities and are highly inter-connected with neighbouring districts, whether geographically, socio-economically, or infrastructurally, tend to experience spikes in COVID-19 cases within weeks of each other. Using a parametric approach of the Pearson correlation, population density was found to have a moderately strong relationship to cumulative COVID-19 cases (p-value of 0.000 and R2 of 0.415) and a weak relationship to COVID-19 infection rates (p-value of 0.005 and R2 of 0.047). Consequently, we provide several non-pharmaceutical lessons, including urban planning strategies, as passive containment measures that may better support disease interventions against future contagious diseases.

Anthrax is a neglected zoonotic disease that remains a global issue because it can cause regular epidemics. Anthrax affects not only health systems but also social-economic conditions, safety, and welfare of the people. This paper aimed to give an overview of human anthrax, prevalence, and prevention in Indonesia. A literature search was performed using search engines such as Google Scholar, Crossref, Mendeley, PLoS One, Elsevier, dan the Ministry of Health official website. The literature used were published between 2015-2020. Anthrax is caused by Bacillus anthracis that affects animals and humans. The virulence factors of these bacteria are determined by the tripartite toxin complex and poly-γ-D-glutamic acid capsule. Anthrax in humans can be found in four forms, namely cutaneous, gastrointestinal, inhalational, and injection anthrax. Each form of anthrax can develop into meningitis and sepsis. Anthrax treatment is commonly done by administering antibiotics. In Indonesia, 14 provinces have been declared anthrax endemic areas. The prevalence of human anthrax in Indonesia is fluctuating and most of it is cutaneous anthrax. Prevention and control of anthrax can be done mainly by vaccination, obeying the rules or standard operating procedures of the authorities, multisectoral cooperation, strengthening anthrax surveillance, increasing resources for diagnosis, increasing public knowledge, and awareness.
