Why outbreaks like coronavirus spread exponentially, and how to “flatten the curve”

Coronavirus disease (COVID-19) is an infectious disease caused by a new virus.The disease causes respiratory illness (like the flu) with symptoms such as a cough, fever, and in more severe cases, difficulty breathing. You can protect yourself by washing your hands frequently, avoiding touching your face, and avoiding close contact (1 meter or 3 feet) with people who are unwell.

HOW IT SPREADS

Coronavirus disease spreads primarily through contact with an infected person when they cough or sneeze. It also spreads when a person touches a surface or object that has the virus on it, then touches their eyes, nose, or mouth.

Prevention

There’s currently no vaccine to prevent coronavirus disease (COVID-19).You can protect yourself and help prevent spreading the virus to others if you:

Do

Wash your hands regularly for 20 seconds, with soap and water or alcohol-based hand rub
Cover your nose and mouth with a disposable tissue or flexed elbow when you cough or sneeze
Avoid close contact (1 meter or 3 feet) with people who are unwell
Stay home and self-isolate from others in the household if you feel unwell

Don't

Touch your eyes, nose, or mouth if your hands are not clean

Simulations Features

The simulation is designed to be simple to use via dropdown menu. the option are self explanatory.

Exponential spread is modelled using a random velocity and random direction, the spread of the virus from sick to healthy is probabilistic based on closeness or collision. The reason why each country is preventing this rapid growth rate to prevent filling up the hospitals to their maximum capacity, forcing emergency rooms to close their doors to new patients. This will likely lead to more deaths due to COVID-19.
