does quarentine really helped??
Answers
Explanation:
Coronavirus disease 2019 (COVID-19) is caused by a new virus that has spread quickly throughout the world. Most infected people either experience no symptoms or suffer mild, flu-like symptoms, but some become seriously ill, and may die.
There is no vaccine (a medicine that stops people catching a specific disease) for COVID-19, so other ways of slowing its spread are needed. One way of controlling the disease is quarantine. This means separating healthy people from other healthy people, who may have the virus after being in close contact with an infected person, or because they have returned from an area with high infection rates. Similar recommendations include isolation (like quarantine, but for people who tested positive for COVID-19) and physical distancing (people without symptoms keep a distance from each other).
Answer:
Currently, there are no effective medicines or vaccines available to treat or prevent COVID-19. For this reason, restrictive public health measures such as isolation, physical distancing, and quarantine have been used in a number of countries to reduce transmission of the virus. Isolation refers to the separation of people with symptoms from others, whereas quarantine is the restriction of people who have no symptoms, but who have had contact with people with confirmed or suspected infection. Quarantine can be implemented on a voluntary basis or can be legally enforced by authorities, and it may be applied at an individual, group, or community level.
This Rapid Review was done in a short space of time as part of Cochrane's organizational effort to meet the need for up-to-date summaries of evidence to support decision-making in combating the effects and impact of COVID-19.
Cochrane researchers used abbreviated systematic review methods to address the following questions as quickly as possible:
- Is quarantine of asymptomatic individuals who were in contact with a confirmed or suspected case of COVID-19 effective to control the COVID-19 outbreak?
- Are there differences in the effectiveness of quarantine in different settings?
- How effective is quarantine when combined with other interventions, such as case isolation, school closures, or antiviral drugs, in reducing transmission, incidence of diseases, and death?
- Is quarantine of individuals coming from a country with a declared COVID-19 outbreak effective in controlling the COVID-19 outbreak?
The authors identified 29 relevant studies. Of these, 10 focused on COVID-19, 15 focused on related evidence on SARS (severe acute respiratory syndrome), two focused on SARS and other viruses, and two focused on MERS (Middle East respiratory syndrome). The 10 studies addressing COVID-19 were all modelling studies simulating outbreak scenarios in China, the UK, and South Korea, and on a cruise ship.
The COVID-19 modelling studies included in the review consistently report a benefit of quarantine measures and show similar findings from studies on SARS and MERS.
The authors of this Cochrane Review concluded that:
- Quarantine of people exposed to confirmed cases may avert high proportions of infections and deaths compared to no measures.
- The effect of quarantine of travelers from a country with a declared outbreak to avert transmission and deaths was small.
- In general, the combination of quarantine with other prevention and control measures, such as school closures, travel restrictions, and physical distancing, had a greater effect on the reduction of transmissions, cases which required critical care beds, and deaths compared with quarantine alone.
- More comprehensive and early implementation of prevention and control measures may be more effective in containing the COVID-19 outbreak.
