The winter season for the majority of the Northern Hemisphere is not a
pleasant time. Temperatures often plunge into the minuses as snow makes
a regular appearance, as does ice, resulting in inevitable pandemonium
for vehicle drivers and walking pedestrians.
Also prevalent at this time of the year are a huge number of colds,
cases of flu, and various respiratory illnesses. Contagious viruses are
of course active throughout the year, but winter is when we are most
vulnerable. When it is cold, many people understandably choose to stay
indoors, meaning a virus can spread rapidly through households.
Flu is transmitted between people when
the infected individual then sneezes or coughs, releasing droplets into
the air. Even touching a surface where the virus has been deposited can
you put at risk of developing said virus.
It is worth noting there is a difference between a ‘cold’ and the
flu, although they have some of the same symptoms and thus, are often
mistakenly self-diagnosed. It is thought that around a third of Brits
assume they just have a ‘bad cold’, when it is in fact the flu. This is a
worrying statistic as thousands die each year from complications
arising from flu.
A runny nose, coughing, a sore throat and sneezing are
characteristics most common in colds, and usually develop over one or
two days, lasting no more than a few days. However, some colds may last
for as long as two weeks.
Flu usually strikes more suddenly than a common cold, symptoms are
more serious and it lasts for a longer period of time. Flu symptoms
include: sudden fever of 38-40°C (100-104°F), aches and pains in muscles
and joints, sweats, a dry cough, headache and a feeling of
exhaustion/needing to lie down.
One to three days following infection is the time when flu symptoms
rear their ugly head, but many find they recover within one week, but a
feeling of tiredness lingers for slightly longer than this. Severe
colds may cause muscle aches and fever, which explains why many people
struggle to differentiate the two.
Regardless of if it is a cold or flu you have, you must seek
medical help if you also have chronic health condition such as asthma,
diabetes, or heart disease, or are experiencing a high fever, a severe
headache, or abdominal or chest pain.
You can take preventative steps though to try and protect yourself and those around you by:
. Coughing or sneezing into a tissue.
. Disposing of used tissues straight away.
. Washing hands as soon as possible.
. Get an annual flu jab if you are in one of high-risk groups.
. Throwing a used tissue away as soon as possible.
. Washing your hands as soon as possible.
. Having a flu jab every year if you’re in an at-risk group (i.e.
children under the age of 5, adults over the age of 65, pregnant women).
Painkillers, such as paracetamol, ibuprofen and aspirin, can help to
ease your symptoms if you just have a cold – although aspirin should not
be given to anyone under the age of 16. You should also rest, drink
plenty of fluids, and eat healthily (a low-fat, high-fibre diet is
generally advised).
You can usually treat yourself in the comfort of your own home if you
have the flu. Make sure to get plenty of rest (most people know when
they feel fit enough to carry on with their normal activities), keep
yourself warm, and drink plenty of fluids.
Paracetamol or anti-inflammatory medicines such as ibuprofen can help
to lower your high temperature and relieve aches if you are unwell with
a fever.
Prescription antiviral medications such as Tamiflu (oseltamivir) are also widely used for both flu prevention and treatment.
Tamiflu stops the chemical neuraminidase – made by the influenzavirus
– from having an impact that is. The virus relies on neuraminidase to
spread in the airways, but because Tamiflu blocks neuraminidase from
having an effect, the spread of the influenzavirus in the airways is
reduced and the body’s immune system is more easily able clear-up the
infection.
