Q) What do we know about immunity from COVID-19?

Most people who are infected with COVID-19 develop an immune response within the first few weeks after infection.

Research is still ongoing into how strong that protection is and how long it lasts. WHO is also looking into whether the strength and length of immune response depends on the type of infection a person has: without symptoms (‘asymptomatic’), mild or severe. Even people without symptoms seem to develop an immune response.

Globally, data from seroprevalence studies suggests that less 10% of those studied have been infected, meaning that the vast majority of the world’s population remains susceptible to this virus.

For other coronaviruses – such as the common cold, SARS-CoV-1 and Middle East Respiratory Syndrome (MERS) – immunity declines over time, as is the case with other diseases. While people infected with the SARS-CoV-2 virus develop antibodies and immunity, we do not yet know how long it lasts.

Q) What is WHO’s position on ‘lockdowns’ as a way of fighting COVID-19?

Large scale physical distancing measures and movement restrictions, often referred to as ‘lockdowns’, can slow COVID‑19 transmission by limiting contact between people.

However, these measures can have a profound negative impact on individuals, communities, and societies by bringing social and economic life to a near stop. Such measures disproportionately affect disadvantaged groups, including people in poverty, migrants, internally displaced people and refugees, who most often live in overcrowded and under resourced settings, and depend on daily labour for subsistence.

WHO recognizes that at certain points, some countries have had no choice but to issue stay-at-home orders and other measures, to buy time.

Governments must make the most of the extra time granted by ‘lockdown’ measures by doing all they can to build their capacities to detect, isolate, test and care for all cases; trace and quarantine all contacts; engage, empower and enable populations to drive the societal response and more.

WHO is hopeful that countries will use targeted interventions where and when needed, based on the local situation.
