VEHICLE TIGHTING THROAT

It starts with a viral infection

Throat inflammation usually starts with an infection caused by true A influenza viruses, enteroviruses, Epstein-Barr virus, Rhinovirus, Coronavirus, Adenovirus, parainfluenza virus, etc. Viruses infecting the nose and throat cause inflammation and gradually destroy the epithelial lining of the nose and throat. This initiates an immune alarm associated with the abundant production of the so-called inflammatory mediators. Mediators of inflammation - bradykinins, cytokines, histamine, etc. destabilize the blood vessels and secretory glands of the nasal mucosa and the local nervous system. The result is the leakage of blood plasma from small blood vessels in the mucosa and abundant mucus secretion causing mucosal edema. Swelling of the mucous membrane blocks the sinuses of the paranasal sinuses, causes complications in the form of: acute mucosal inflammation, sinusitis and pharyngitis.



Symptoms of sore throat

Symptoms of pharyngitis are: difficulty in swallowing caused by acute pain and malaise. Often accompanied by a runny nose and a dry cough. The mucous membrane of the throat is congested. If the symptoms of sore throat exacerbate and persist for over 3 days or worsen - the development of bacterial infection and purulent streptococcal angina may be presumed. Report this type of symptoms to your contact doctor.


Causes of sore throat

The reason for easy infection of the throat and nose may be the physiological protection of the nose against germs, and especially against viruses. The flow of air through the nose in normal conditions takes place through both nasal cavities, but one of them always puts more resistance to the air flowing through. These changes occur cyclically every 3-8 hours. This physiological blockage results from alternating contraction and dilatation of venous sinuses and does not require correction. Impaired nasal breathing can lead through the nasopharyngeal reflex, to the increase of bronchial resistance and impaired lung ventilation.


Diseases that damage the physiological shield against germs

The main diseases that damage the nasal mucosa are: frequent acute cold infections, allergies and vasomotor non-allergic rhinitis. These causes cause chronic acute inflammation of the nose and throat, which is accompanied by high activity of immune cells and the production of a large amount of substances irritating the mucous membrane - the so-called inflammation mediators (bradykinin, cytokines, histamine, etc.). Chronic viral infections, allergies, asthma, lung disease, etc. diseases damage the physiological shield against germs - the ciliary mucosa.


Throat immune protection - Waldeyer's throat ring.

This mysterious sounding name means a specific immune barrier in the throat closely related to the entire immune system. It is a local "defensive" defense in the mucous membrane of the throat - extremely responsive to pathogenic viruses and bacteria. They are immune cells, lymphocytes, etc., interferons, antibodies, etc. Chronic viral infections, allergies, asthma, lung disease, weakness of immunity due to systemic diseases weakens the immune self-defense of the throat.
 

How this disease attacks

The throat is a common vestibule of the alimentary and respiratory tract. It is therefore a place of particular exposure to constant contact with viruses, bacteria and other substances contained in the inhaled air and food intake. Thus, acute inflammations of the throat include the mucous membrane of the throat as well as the lymphatic tissue.


Who is attacking the pharyngitis?

Throat inflammation is also common in children and adults.However, due to the immaturity of the immune system, small children are particularly at risk. The peak of illness usually occurs between 4 and 7 years of age. The most common diseases occur in the cold season, and the increased risk of illness includes children attending nurseries and kindergartens.


What is the acute throat inflammation?

Severe pharyngitis generally starts as a viral infection. Symptoms of acute throat inflammation are difficulty in swallowing caused by acute pain and malaise. Often accompanied by a runny nose and a dry cough. The mucous membrane of the throat is congested. If the symptoms persist for more than 3 days or get worse, see a doctor.

VIRUS ANGINA

Which germs cause angina viral?

It is believed that viral infection is the cause of acute tonsillitis in more than 70% of cases. The most common are infections caused by: adenoviruses, rhinoviruses, coronaviruses, enteroviruses (Coxackie virus), RS, parainfluenza, Epstein-Barr virus.

What circumstances trigger viral angina?

The initiation of this form of angina is favored by strong infections of cold and runny nose viruses and other factors that weaken the local resistance of the throat. An important role in the development of bacterial angina is residing in the throat of a small number of pathogenic bacteria from the group of streptococci and the local local weakness of the immune system, which allows their rapid development.

Symptoms of viral angina

This is called angina erythematosus, which is characterized by congestion of the mucous membrane - palatal arches, tonsils and posterior pharyngeal wall. There are no raids on the tonsils, only serous exudate in the tonsides. Symptoms of acute rhinitis and laryngitis often coexist. Viral warts usually last for 5-7 days, the symptoms of streptococcal angina persist longer, and the symptoms of infectious mononucleosis may be present for many weeks.

OTHER CAUSES OF THROAT PAIN

Sore throat and colds

Pain usually accompanies colds and flu. In the case of colds, this is a common occurrence. In the case of influenza, it occurs only sometimes.

Sore throat caused by mechanical injuries.

Small children put on the face, deliberately or accidentally, various objects that can cause rubbing or injury to the mucous membrane of the throat. In such cases, you should go to the doctor with your child.

Sore throat associated with acute infectious children's diseases:

- rubella,
- Chickenpox
- measles (before the onset of rash) and may persist for several days.

Pain accompanying the inflammation of the mouth

Severe sore throat is also accompanied by herpetic stomatitis. The child then has difficulty swallowing fluids. In turn, severe sore throat obstructing swallowing, fever, enlargement of the tonsils with the presence of secretion on them is characteristic of scarlet fever and infectious mononucleosis. The child must necessarily check with a doctor who will recommend appropriate treatment.
