The common colds and influenza
People can develop colds throughout the year, but it is more common in late winter
and early spring. Colds are not caused by cold or rainy weather, but by viruses such
as rhinoviruses (there are more than 100 different varieties) and corona viruses. You will develop immunity against a virus that makes you ill, which lasts for a few years.
Most viruses can make you ill only once, but because there are so many cold causing
viruses, a person can have multiple colds through their life. The average adult has two to three colds per year, while children get up to twelve colds per year.
Colds viruses are carried on the hands of infected people, and are transmitted from
person-to-person by direct contact, by touching contaminated surfaces (such as
counter tops, telephones or door handles) and then touching your nose or mouth, or by inhaling droplets containing viral particles, released when a person with a cold
breathes, sneezes or coughs. Influenza tends to occur in epidemics, especially during winter, causing severe illness
in millions of people, and leads to between 250,000 and 500,000 deaths worldwide. Influenza viruses can also cause pandemics, such as that of 1918, which killed at least
20 million people. Influenza is caused by a group of viruses, the orthomyxoviruses. Three types of influenza virus are known, namely A (related to swine, equine and
avian flu, and responsible for most epidemics in humans), B (causes small epidemics every 3 to 6 years) and C (cause minor upper respiratory tract infection and is
Both the common cold and influenza start with a scratchy, sore throat, followed by a
runny nose and nasal congestion on the second day. Influenza however starts more abruptly compared to the gradual onset of a cold. A productive (wet) cough may
develop, which will eventually become dry. Influenza also causes other symptoms not
typically associated with the common cold, such as headache, fever, general weakness and aching joint and muscle aches. A person suffering from influenza looks
ill, and wants to stay home and sleep or rest (malaise). The symptoms will last about seven to ten days and will go away on their own. A person suffering from a cold can
usually go to work or school. Complications of both infections include sinusitis, lower
respiratory infections, such as pneumonia or bronchitis and otitis media (middle ear infection).
There is no treatment that can cure a cold or flu, only the symptoms can be relieved.
It is often said that a cold or influenza will resolve in seven days with symptomatic
treatment, and one week if it is not treated.
