- Indian Prime Minister recently announced 21-day lockdown period in the entire country to contain the COVID- 19 pandemic.
- 21day quarantine was encouraged extensively during Ebola crisis as well.
- The calculations are based on the estimated incubation period of the virus in the human host.
- Usually, incubation period for any infection is 14 days epidemiologically.
- Another week is added to ensure that the infection dies out and the host is entirely safe.
- Since, this is a novel corona virus, the scientists have estimated the time between entry of virus to the onset of infection, falls within this period, known as median incubation period.
- It was also recently reported that the median incubation period for COVID19 is just over ﬁve days.
- 97.5% of people who develop symptoms do so within 11.5 days of infection.
- This is the most eﬀective way of preventing the spread of infection.
- Maintaining personal hygiene and practising personal distancing are other ways of prevention.
Important value additions:
- Ebola virus disease (EVD) is also known as Ebola haemorrhagic fever.
- It is viral haemorrhagic fever of humans and other primates caused by ebolaviruses.
- The virus causes severe bleeding, organ failure and can lead to death.
- Humans may spread the virus to other humans through contact with bodily fluids such as blood.
- Quarantine is a restriction on the movement of people and goods which is intended to prevent the spread of disease or pests.
