Why social distancing might last for some time
Near the end of World War One, a nasty flu started spreading around the world. The virus responsible for the disease, which became known as Spanish flu, infected over a quarter of the world's population. With an estimated death toll of between 50 million and 100 million, it was one of the deadliest pandemics in human history.

Uncertain Time Frame

Top experts say the virus is going to be circulating for a year or two and can keep infecting people, causing outbreaks until there is a vaccine or treatment to stop it. If we drop the unpleasant and strict measures, the virus outbreak can know no boundaries or limits of infections. It won’t simply go away in two weeks.

Guidelines by WHO

  • Wash your hands regularly, and for at least 20 seconds.
  • Cover your cough or sneeze with a tissue, then dispose of it properly.
  • Clean and disinfect doors, handles and objects that are touched all the time.
  • Contact a health professional if you have symptoms; fever and a dry cough are most common.
  • DON’T touch your face.
  • DON’T go out of your home.

  • Pandemic is a worldwide spread of a new disease. 
  • Epidemic

Public health measures

  • Social distancing is a slew of tactics meant to keep people at a six feet distance from each other to keep droplets from an infected person's nose or mouth from landing on another person.
  • Quarantine is restricting the movement of, or isolating, people who might have been exposed to an infection but who aren't sick.
  • Isolation is separating people with confirmed or probable infections from other healthy people.
  • Lockdown is a term used by public health officials or lawyers to refer to anything from mandatory geographic quarantine to non-mandatory recommendations to shelter in place, to anything in between.
  • Cordon sanitaire is the restriction of movement in and out of a region or city.
  • Shelter in place is an order requesting people to stay at home, except for trips to the grocery store, pharmacies, and other essential errands.

Medical equipment

  • A ventilator is a machine that assists a patient in breathing when they have trouble breathing on their own.
  • PPE (Personal protective equipment), such as masks, gloves, face shields, and other gear that keeps health care workers from catching an infection.
  • A respirator is a face mask that seals around the mouth and filters out particles from the air before they are breathed in.
  • Surgical mask or face mask are loose-fitting masks that don't filter out all the particles but stop a wearer from spreading droplets of contagion when they sneeze or cough.

Disease Event Classification

Epidemiology is the branch of medicine that handles the following:

  • Incidence: the occurrence of a disease over a specified period.
  • Prevalence: how many people are affected within a population.
  • Control of diseases: an appropriate public health response.

Two measurable factors mostly define the level of disease occurrence:

  • The pattern and speed by which a disease moves.
  • The size of the susceptible population.

The terms an epidemiologist use

  • Sporadic refers to a disease that occurs infrequently or irregularly.
  • Cluster refers to a disease that occurs in larger numbers even though the actual number or cause may be uncertain.
  • Endemic refers to the constant presence and/or general prevalence of a disease in a geographic population.
  • Hyperendemic refers to persistent, high levels of disease well above what is seen in other populations.
  • Epidemic refers to a sudden increase in the number of cases of a disease above what is normally expected.
  • Outbreak is the same as an epidemic but is often used to describe a more limited geographic event.
  • Pandemic refers to an epidemic that has spread over several countries or continents, usually affecting a large number of people.
