People of all ages who experience fever and/or cough associated withdifficulty breathing/shortness of breath, chest pain/pressure, or loss of speech or movement should seek medical attention immediately.
How does COVID 19 spread ?
People can catch COVID-19 from others who have the virus. The disease spreads primarily from person to person through small droplets from the nose or mouth, which are expelled when a person with COVID-19 coughs, sneezes, or speaks. These droplets are relatively heavy, do not travel far and quickly sink to the ground. People can catch COVID-19 if they breathe in these droplets from a person infected with the virus. This is why it is important to stay at least 1 meter) away from others. These droplets can land on objects and surfaces around the person such as tables, doorknobs and handrails. People can become infected by touching these objects or surfaces, then touching their eyes, nose or mouth.

COVID-19 is mainly spread through respiratory droplets expelled by someone who is coughing or has other symptoms such as fever or tiredness. Many people with COVID-19 experience only mild symptoms. This is particularly true in the early stages of the disease. It is possible to catch COVID-19 from someone who has just a mild cough and does not feel ill.Some reports have indicated that people with no symptoms can transmit the virus.

A “novel” coronavirus means that it is a new coronavirus that has not been previously identified in humans. This means it is different from coronaviruses that cause the common cold, and those that caused SARS in 2002 and MERS in 2012.
Like, SARS and MERS, the novel coronavirus is a zoonotic disease. The definition of a zoonotic disease is one that begins in animals and is transmitted from animals to people.
