COVID-19 was first detected in Wuhan, Hubei Province, China. The virus spread rapidly, prompting the World Health Organization (WHO) to classify COVID-19 as a global pandemic. In Indonesia, the virus spread at a fast pace. According to WHO data, there have been 6,535,354 COVID-19 cases globally, with 387,155 deaths.

In Indonesia, there have been 29,521 confirmed cases with 1,770 deaths, while in West Nusa Tenggara (NTB), 798 cases and 22 deaths have been reported. The high number of cases has placed significant stress on the public, both mentally and physically, due to the pressures brought on by the pandemic.
