Quarantine effective for control of COVID-19

Embargoed until: Publicly released:
Peer-reviewed: This work was reviewed and scrutinised by relevant independent experts.

Systematic review: This type of study is a structured approach to reviewing all the evidence to answer a specific question. It can include a meta-analysis which is a statistical method of combining the data from multiple studies to get an overall result.

People: This is a study based on research using people.

A new Cochrane review has summarised the evidence available from modelling studies that show how quarantining affects the spread of COVID-19. All the studies found quarantine to be important in reducing the number of people infected and the number of deaths. Results showed that quarantine was most effective, and cost less, when it was started earlier. Combining quarantine with other prevention and control measures had a greater effect than quarantine alone. While early quarantine combined with other public health measures may reduce spread of the disease, there are still uncertainties around how these measures can best be adopted and when they can be relaxed.
