Essential tips and cold and flu prevention


The common cold and flu are caused by viruses that spread from person to person. Ways you can contract cold and flu include:

  • Breathing in tiny droplets containing the viruses that are launched into the air every time someone who has a cold or flu sneezes, coughs or speaks.
  • By touching a contaminated surface, like a tissue used by an infected person, door handles, hand rails and telephones, and then touching your nose or eyes
  • Avoid contact with an infected person


What’s the difference between a common cold and flu?

It’s sometimes hard to tell. Many of the symptoms are the same and both are caused by viruses, not bacteria, which means you can’t treat colds and flu with antibiotics. Cold symptoms are generally milder than those of flu, and they do not tend to lead to any serious health complications, which flu can.

The common cold at a glance

The common cold is a viral infection affecting the upper respiratory system. Causes include rhinoviruses, respiratory syncytial virus (RSV), parainfluenza virus, adenovirus and coronavirus. Symptoms can appear within 10-12 hours of exposure and can include:

  • Runny nose
  • Sore or irritated throat
  • Coughing
  • Sneezing
  • Low-grade fever (mostly in young children)

Flu at a glance

There are three types of flu virus. Type A viruses cause most cases of human flu and some disease in animals. Type B are less common and cause less severe illness. Type C viruses usually only cause mild flu and are rare. Symptoms of flu tend to be more serious than those of the common cold and can include:

  • Sudden fever (usually 39°C or above)
  • Dry cough
  • Achy muscles
  • Headache
  • Sore throat
  • Extreme tiredness
  • Runny or blocked nose
  • Nausea, vomiting and diarrhoea (more common in children)

How Long is Flu Contagious?

The incubation period for flu is usually 1-3 days after exposure. If you have picked up a flu infection, you can infect someone the day before your symptoms develop, and sometimes up to five days after your symptoms appear. That means you can pass on the flu to someone else before you know you have it.

Most people make a full recovery from flu, but it can lead to complications

including bronchitis, pneumonia and in rare cases meningitis.

Five ways to beat colds and flu this winter

Germs are everywhere and you come into contact with about 60 000 of them everyday. This is according to Philip M. Tierno, author of The Secret Life of Germs: Observations and lessons from a Microbe hunter. But, he adds that only 1-2% of these may be harmful.

By touching a contaminated surface, like a tissue used by an infected person, door handles, hand rails and telephones, and then touching your nose or eyes you become more susceptible to this percentage of harmful germs.

Here are Dettol’s five tips on how you can protect yourself and your family:

  1. Wash your hands – a lot: If you have come in contact with someone who is contagious, getting rid of the germs with a sanitising handwash can stop a cold in its tracks. Sanitising handwipes, or a hand sanitiser
  2. Use sanitising wipes or try and keep some of the ten germiest hotspots clean. These are wallets or purses, remote controls, public bathrooms, shopping trolleys, cutting boards, yoga mats, schools, doctors rooms, restaurants and offices
  3. Light exercise: Research presented to the British Journal of Sports Medicine says that you are 50% likely to get a cold if you feeling fit are active.
  4. Get enough sleep: A tired body is less able to fight a virus.
  5. Stay away from sick people: Avoiding contact with infected people prevents your chances of infection.
