Every cold season we meet everywhere with runny noses, coughing and wheezing. It speaks of colds, flu or infection - but what lies behind these terms? We will try to explain these meanings, because differentiation between cold and flu are no longer a problem.


What does a cold?

By colds describe a viral disease that is manifested by colds, coughs and other general symptoms. Over 200 types of viruses can cause a cold, so it is possible to get a cold several time consecutively for short periods of time.

Pathogens are so varied (rhinovirus, adenovirus and coronary virus) vaccination that is not possible - but fortunately, usually these disorders not life-threatening us. Colds are more common in cold weather, but summer colds are possible. But true influenza infections are completely different.


How to install the flu?

The flu is caused by influenza virus. This virus is ordered into 3 groups and their genetic material is constantly changing - therefore exposed persons are recommended annual vaccination against influenza. The problem of influenza infection is the disease with typical cold symptoms but much more accentuated, which can affect the lungs (pneumonia), heart (pericarditis) or brain (inflamed tissue).

In recent years we have faced a number of infectious diseases with symptoms of influenza, which have sparked a wave of international concern - SARS and bird flu are just two examples of viral infections that can be dangerous to humans.


Feels like cold and flu?

Cold and Flu is manifested initially through the same discomfort and the same symptoms. A sore throat, runny noses, coughing and wheezing are typical symptoms. Most often followed by chills indicate an increase in temperature is accompanied by fever and chills waves. Add to this the headaches and limbs, sore throat, general weakness and loss of appetite. However, completes the picture of the disease. If actual flu symptoms and discomfort are spontaneous and very strong, so that its victims can call exactly when flu was triggered.

Diseases that starts with cold or excessive tearing of the eyes are manifold, eg allergies to pollen or dust. By catarrh, coughs, hoarseness makes its presence felt and another group of diseases - those of childhood: measles, mumps, rubella, etc. After a few days but appear irritation to the skin, thus simplifying the diagnosis. In case of repeated or long-term illness among children, a possible cause could be a hereditary immunological defect, but up to six colds per year during childhood is not a concern.


Stuffy nose, typical symptom for colds

Stuffy nose has a frequency of 80% in cases of colds. Once cold spreads to the sinuses, we are already talking sinusitis. A mild infection of connective tissue or an extension of pathogens in the eardrum (the Eustachian tube) leading to an infection of the eardrum in the first days of illness. When viruses extend to the lungs, bronchi cough indicate impairment (acute bronchitis) which can turn into pneumonia if they do not interfere with treatment.

Including among children, the banalest colds can lead to a deterioration of general condition. Babies breathe almost exclusively through the nose - and refuse to drink fluids when they have a runny nose, because the exchange between breathing and swallowing is too difficult. The little ones, mucosal inflammation often leads to infection of the eardrum.

The nose is almost always affected the common cold, as well as paranasal sinuses, eyes and ears, and bronchi, fortunately rarer. While in case of common colds, extending to neighboring organs, paranasal sinuses, eyes or bronchi, it can be seen as a complication if influenza influenzas can be affected lungs, heart or brain. Extending viruses can cause pneumonia, pericarditis or inflammation of brain tissue.

Given that the disease weakens the immune system and mucous membranes are sensitive, it is easier for bacteria to grow (eg pneumococcal) can cause so-called superinfection (secondary infection). Viral pneumonia overlaps with the bacteria.


Getting a diagnosis

• History (setting journey disease). The duration and severity can determine whether we are dealing with a cold or flu.

• Clinical examination (control) includes inspection (visual examination), palpation (examination by hand), percussion (tapping and repeated) and auscultation (examination of internal organs by listening with a stethoscope). A runny nose is easily recognized by lining red, swollen, and if tapping the forehead or cheek bones causes pain, often indicate a sinus infection. If the eardrum infection by using otoscope will be seen reddened eardrum and fluid even in the back. Mouth and throat are often red and inflamed tonsils are the secondary bacterial infection or if, shows even white dots on the surface. If cough, by listening with a stethoscope, you can hear noise from the bronchi. In case of pneumonia, breathing sound is modified in the affected area.

• ultrasounds, radiographs, computed tomography (CT) and magnetic resonance imaging (MRI). Most times, diagnostic imaging procedures are unnecessary in cold case. An acute sinus infection can be identified using ultrasound or radiography. To rule out the possibility of pneumonia, in most cases it will call the method of radiography. CT and MRI procedures are used in case of an avian influenza dramatic progress to exclude damage to the heart or brain.

• extensive examinations in case of complications. When there is suspicion of a secondary bacterial infection, can achieve a pharyngeal exudate, sampling may mucosa or blood tests to determine the exact type of pathogens. In case of pneumonia, radiographs indicate the disease - infection gives a date of beginning treatment or formed an abscess? In case of pericarditis, heart rhythm changes, which can be controlled by an electrocardiogram (EKG). ( for more health tips visit http://health-tips.ca )


The importance of a competent immune system

Competent immune system is the basic condition to be able to get healthy winter. A diet rich in vitamins, fruits and vegetables in full motion long outdoor sauna sessions or regular application methods Kneipp Kneipp (methods using water in treatment and prevention of diseases extremely varied) are just a few ways strengthening the immune system. A weakened immune system will allow the infection to manifest consecutively with symptoms becoming more pronounced.

Besides eating and movement recommended, there are several tips you can follow the season of colds: Avoid other people shaking hands, avoid crowded situations and practice inhalations. Real flu there is only one remedy: annual vaccination. Mainly older people, chronically ill patients are considered risk -they should pay special attention to influenza and pneumococcal vaccination.

Given that the genetic material of influenza viruses is changing, protection by a vaccine should be repeated annually.


Traditional recipes and remedies against colds

Every family is transmitted from generation to generation prescriptions and remedies against colds and influenza - be it the aunt onion tea or chicken soup we eat in childhood. Many of these recipes are so effective that even we do not need anything else to cure a cold. Do not forget inhalations as they will help inflamed mucosa of the nose to clear.

If headaches and limb, often help a painkiller or a pharmaceutical product colds issued without prescription - be it aspirin, paracetamol or another active ingredient. Note: because of side effects, never treat children with acetylsalicylic acid (aspirin)! Given that both viral infections and flu are caused by viruses, antibiotics will not help. They will be included in treatment only if installing a secondary bacterial infection. If the symptoms persist for an extended period, consult a doctor to avoid any serious complications!
