What is a cold?

The common cold is a viral infection of your upper respiratory tract (that is, your nose and throat). More than 200 types of viruses can cause a cold,¹ though they are usually caused by a type of virus called rhinoviruses. Symptoms of a cold tend to peak about 1 to 3 days after you get infected, and typically last 7-10 days.^2,3 In some cases though, they can linger for more than 3 weeks.^2,3

How to prevent catching a cold?

Colds are spread by coming into contact with virus particles, for example by touching surfaces that an infected person has touched (e.g., door handles) or when you come into contact with an infected person’s cough or sneeze.

To avoid catching a cold, practice good hygiene by:

• Washing your hands regularly and properly with soap and water, and avoid touching your face with unclean hands
• Prevent spreading the cold by sneezing and coughing into your elbow or a tissue (then throwing it away immediately)
• Clean commonly touched surfaces regularly
• Avoid sharing personal items like cups, plates, cutlery and towels
• Stay home if you are sick and avoid close contact with others

Be aware that antibiotics aren’t effective against colds or the flu, as they only treat illnesses caused by bacteria, while colds and the flu are caused by viruses.

What is the flu?

The flu, or influenza, is a highly contagious viral infection caused by the influenza virus, primarily strains called influenza A and B. Have you ever wondered, is it a cold or the flu? It may help to remember that flu symptoms typically start suddenly, and a key sign of having the flu vs cold is the presence of a fever, which can last 3-4 days.³ While the flu can be mild, it can also cause serious illness in otherwise healthy people. There is often an outbreak of flu every year during winter, and how bad it depends on the strain and strength of the virus, and how susceptible the community is to infection.

How to prevent catching the flu?

Like colds, influenza viruses can be transmitted by close contact with an infected person, so good hygiene practices like washing hands frequently and covering coughs and sneezes is important to prevent the spread.

However, one of the most important strategies for preventing the flu is getting a flu vaccination. Vaccination is the best way to reduce your risk of contracting the flu, as well as reduce your risk of serious illness if you do become infected. The influenza virus can change from season to season, so it’s important to get a vaccination every year. Annual flu vaccination is recommended for everyone over 6 months of age,^4,5 and it is free for certain groups of people who are considered to be at greater risk of complications from the flu.

There is no vaccine for the common cold.

How to relieve the flu?

Colds and flu can be treated in similar ways. If you are suffering from flu symptoms, you can relieve them with rest and self-care at home, using similar strategies to relieve symptoms of the common cold.
