What is the percentage of people who need to be immune against COVID-19 in order to achieve herd immunity?
We are still learning about immunity to COVID-19. Most people who are infected with COVID-19 develop an immune response within the first few weeks, but we don’t know how strong or how long that immune response is or how it differs for different people. There were also reports of people infected with COVID-19 for the second time. Until we better understand immunity to COVID-19, it will not be possible to know how much of the population is immune and how long that immunity lasts, let alone make future predictions. These challenges should prevent any plans that try to increase immunity within a population by allowing people to become infected.
Why is herd immunity important in the context of the COVID-19 pandemic? Herd immunity occurs when a large part of the population becomes immune to an infectious disease, usually through vaccination – thereby limiting the risk of person-to-person transmission of the infection through the community.

Social and physical distancing measures aim to slow the spread of the disease by stopping the chains of transmission of COVID-19 and preventing the emergence of new ones. These measures ensure physical distance between people (at least one meter) and reduce contact with contaminated surfaces, while encouraging and maintaining virtual social connection within families and communities.

There is currently no evidence that food or food packaging is linked to the transmission of COVID-19. Unlike food-borne gastrointestinal (GI) viruses such as norovirus and hepatitis A, which people often get sick from through contaminated food, SARS-CoV-2, which causes COVID-19, is a virus that causes respiratory disease, not gastrointestinal disease. , and food exposure to this virus is not known to be a route of transmission. It is possible that a person can get COVID-19 by touching a surface or object that has the virus on it and then touching their own mouth, nose or possibly eyes, but this is not thought to be the main way the virus spreads.
