⭐ Core Definition: COVID-19 testing

COVID-19 testing involves analyzing samples to assess the current or past presence of SARS-CoV-2, the virus that causes COVID-19 and is responsible for the COVID-19 pandemic. The two main types of tests detect either the presence of the virus or antibodies produced in response to infection. Molecular tests for viral presence through its molecular components are used to diagnose individual cases and to allow public health authorities to trace and contain outbreaks. Antibody tests (serology immunoassays) instead show whether someone once had the disease. They are less useful for diagnosing current infections because antibodies may not develop for weeks after infection. It is used to assess disease prevalence, which aids the estimation of the infection fatality rate.

Individual jurisdictions have adopted varied testing protocols, including whom to test, how often to test, analysis protocols, sample collection and the uses of test results. This variation has likely significantly impacted reported statistics, including case and test numbers, case fatality rates and case demographics. Because SARS-CoV-2 transmission occurs days after exposure (and before onset of symptoms), there is an urgent need for frequent surveillance and rapid availability of results.

👉 COVID-19 testing in the context of COVID-19 pandemic

The global COVID-19 pandemic (also known as the coronavirus pandemic), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), began with an outbreak in Wuhan, China, in December 2019. Soon afterward, it spread to other parts of Asia and then worldwide in early 2020. The World Health Organization (WHO) declared the outbreak a public health emergency of international concern (PHEIC) on 30 January 2020, and assessed it as having become a pandemic on 11 March. The WHO declared the public health emergency caused by COVID-19 had ended in May 2023.

COVID-19 symptoms range from asymptomatic to deadly, but most commonly include fever, sore throat, nocturnal cough, and fatigue. Transmission of the virus is often through airborne particles. Mutations have produced many strains (variants) with varying degrees of infectivity and virulence. COVID-19 vaccines were developed rapidly and deployed to the general public beginning in December 2020, made available through government and international programmes such as COVAX, aiming to provide vaccine equity. Treatments include novel antiviral drugs and symptom control. Common mitigation measures during the public health emergency included travel restrictions, lockdowns, business restrictions and closures, workplace hazard controls, mask mandates, quarantines, testing systems, and contact tracing of the infected.

COVID-19 testing in the context of COVAX

COVID-19 Vaccines Global Access, abbreviated as COVAX, was a worldwide initiative aimed at equitable access to COVID-19 vaccines directed by the GAVI vaccine alliance, the Coalition for Epidemic Preparedness Innovations (CEPI), and the World Health Organization (WHO), alongside key delivery partner UNICEF. It was one of the four pillars of the Access to COVID-19 Tools Accelerator, an initiative begun in April 2020 by the WHO, the European Commission, and the government of France as a response to the COVID-19 pandemic. COVAX coordinated international resources to enable low-to-middle-income countries equitable access to COVID-19 tests, therapies, and vaccines. UNICEF was the key delivery partner, leveraging its experience as the largest single vaccine buyer in the world and working on the procurement of COVID-19 vaccine doses, as well as logistics, country readiness and in-country delivery.

By 19 October 2020, 184 countries had joined COVAX.

COVID-19 testing in the context of COVID-19 surveillance

COVID-19 surveillance involves monitoring the spread of the coronavirus disease in order to establish the patterns of disease progression. The World Health Organization (WHO) recommends active surveillance, with focus of case finding, testing and contact tracing in all transmission scenarios. COVID-19 surveillance is expected to monitor epidemiological trends, rapidly detect new cases, and based on this information, provide epidemiological information to conduct risk assessment and guide disease preparedness.

COVID-19 testing in the context of 2020 Singaporean general election

General elections were held in Singapore on 10 July 2020 to elect members of Parliament. They were the fifteenth general elections since the introduction of self-government in 1959 and the thirtheenth since independence in 1965. Parliament was dissolved and the general election called by President Halimah Yacob on 23 June, on the advice of Prime Minister Lee Hsien Loong. The number of elected seats was increased from 89 to 93 from the previous election.

The election was significantly influenced by the COVID-19 pandemic, which became a central issue in the campaign. The ruling People's Action Party (PAP) emphasised its management of the crisis, including securing supplies of face masks and ramping up testing. In contrast, opposition parties criticised the government's handling of the pandemic, particularly the high number of COVID-19 cases in foreign worker dormitories and the Ministry of Health's reversal of its guidance on mask usage. Beyond the pandemic, other key issues that emerged during the election included the cost of living, housing affordability, population growth and immigration policies. The election also featured constituency political broadcasts, a televised programme hosted by Mediacorp, which replaced physical rallies that were suspended as part of social distancing measures.
