Upper respiratory tract infection : causes, complications, diagnosis and treatment

The most common infection in the human population is the upper respiratory tract infection.

The upper respiratory tract covers the Anatomical structure like the pharynx, paranasal, nose proximal part of the trachea, and lyrics.

Most acute forms of upper respiratory tract infection are caused by viruses and bacterial pathogens can also responsible for this infection.

They also cause chronic infection some upper respiratory tract infections because of many complications like sudden airway obstruction caused by epiglottis and diphtheria.

The area which is included in the upper respiratory system larynx with subglottis area of trachea nasal cavity pharynx and nose. In a normal way center in the respiratory by nostrils where it cleaned humidified and heat up in the inner side of the nasal cavity.

Normally air passes from the pharynx to the larynx then enters into the trachea then next to the lower respiratory tract.

 A non-adaptive portion of the upper respiratory tract change standard of inhaled air also affects the activity of the tracheobronchial tree and lungs. Standard mostly common infection in the population for upper respiratory tract infection they include common cold self-limiting disease nasopharynx syndrome swollen and paining of the nasal cavity rhinosinusitis and also swollen of pharynx hypopharynx tonsil and uvula.

Natural occurrence of disease

The major cause of the upper respiratory tract infection is the bacteria and virus which enter the mucosa. Almost upper respiratory tract infections spread from one person to another one come in contact with each other secretion from hand or by breath in the respiratory droplets.

The protective system includes humoral physical-mechanical and cellular immune defense. There are some mechanical hurdles like hair in the nose that protect yourself from pathogens by capturing them from they are entering the stomach. 

Sign and symptoms

These are the following sign and symptoms of the upper respiratory tract.

  • Infection running nose to nasal obstruction cough which most common is the dry increased rate of the citizen.
  • Fever which up and down with time. It is mostly found in children which are younger than 5 years. In some cases, fever cannot be notified.
  • The specific type of virus is responsible for diarrhea which is an upper respiratory tract infection.
  • In the case of infants, the symptoms are most common like easy crying decreases.
  • Desire to eat vomiting time of sleeping is also disturbed and breath problem in younger infants. In older children most common type of symptom chill and headache.

Diagnostic options


As almost all infections of the upper respiratory tract infection are caused by different kinds of viruses and there or not the availability of suitable therapies for any kind of viruses. During testing, some kind of virus cannot be indicated except several viruses like influenza and patient of the immunocompromised. In some cases, several types of searches are performed for the bacteria causing infections.

In most cases, there is a group of infections that are caused by a streptococcal certainly with colloquially, pharyngitis which is known as strep throat. Ten percent of cases of pharyngitis in adults are caused by the B hemolytic Streptococcus agent is most common which is notified. There is some clinical future which is civil length arithmetic for 24 hours fever with a temperature of 38 degrees centigrade at least. Tender anterior lymph nodes. The absence of the cough is notified as common in the cause of viral illness.

The age of patients is between 5 to 15 years if clinical symptoms or at a higher level then there is no requirement of many tests and start the use of the antibiotics as possible.

When the diagnosis is not identified then there is a need for any kind of the for test if an antigen like a group of a strip Tokas is given then it is showing result in about half an hour and it is very satisfactory. Throat culture used to lead in the process of indication and investigation of the breakdown of group B hemolytic disease which helps in the distribution of antibiotic-resistant in most cases search for bacterial causative cannot be indicated with the suspected culture of the bacteria.

In a real dangerous equation, sinus puncture aspiration can be performed by the person which is fully trained for it. If the disease shows a prolonged effect then a search is compulsory for an agent that can be able to cause rhinosinusitis. In some cases tests for the identification of diphtheria performed which are very specific.

Nasal endoscopy and Laryngoscopy

Nasal endoscopy performs an important role in the recognition of the disease but it is not used to the patient with the severe off disease who require special interaction for the first time but it is used only to those who observe an excess of a symptom of the disease.

Some major types of URTI

Rhinitis and Rhinosinusitis

Rhinitis mostly referred to swelling of the membrane of the nose which includes the nose which is running, it also includes are characterized by centers and also difficulties in breathing with the nose instead of the mouth. There are two classes of rhinitis which are chronic and acute this acute and chronic rhinitis based on time off symptoms and change of fluid of nose.

Acute viral common cold

An acute effect of rhinitis almost part of an upper respiratory tract infection which is famous as the name of the common cold. The rhinovirus of human beings is responsible for 50 to 80% of all common cold it is also signed by various which is known as the Coronavirus adenovirus influenza virus they are also different varieties of viruses like respiratory syncytial virus or enterovirus.

The infection of the common cold is varied by age. In the case of children who are younger than 5 years which have almost a 38 percent chance of common cold per year, it is an average of common cold disease.

Acute Bacterial Rhinosinusitis

Children are the most famous for this and signs of acute bacterial rhinosinusitis and fever difficulty in breathing flow of the tidal fluid. These are some common symptoms of acute bacterial Rhino sinusitis some other symptoms of acute bacterial rhinosinusitis for more than 10 days are moderate to high-grade fever. It is a sugar state a secondary infection of the bacteria inpatient with symptoms of acute bacterial rhinosinusitis is the purulent discharge of fluid from the nose which is never controlled with the help of medicines.

Hyposmia is common in the case of an adult which pain is the most noted symptom. The cough in acute bacterial rhinitis is the most common notified and it shows excess in the early morning or beginning of the day after waking up is a result of the addition of the secretion during the whole night in the posterior pharynx. The increasing quantity of Beta-lactamase secrets. Pathogen upon upper respiratory tract separation.

Chronic rhinitis

Chronic rhinitis disease a prolonged effect of viral rhinitis. Prolonged inflammation or effect is caused by a lower amount of humidity and airborne hurdles may include in it.

It may be also present in chronic infected diseases which are included syphilis blastomycosis, histoplasmosis, and tuberculosis. All of these diseases or called by the formation of granulomas resulting in the breakdown of the soft tissue bone and cartilage. Chronic rhinitis has many more symptoms but, which included a hurdle in the nasal cavity, acute discharge, and flew off blood also included.

A special type of chronic rhinitis is chronic atrophic rhinitis. Atrophic rhinitis maybe contains two types which are primary atrophic rhinitis which is also called Ozona and other is secondary atrophic rhinitis.

Acute bacterial pharyngitis

Acute bacterial pharyngitis and tonsillopharyngitis mostly occur in the season of the month which are colder than normal months. The most common and abundant case of acute bacterial pharyngitis and tonsillopharyngitis is A beta-hemolytic Streptococcus which causes 15 to 30 percent of most almost cases of pharyngitis in case of children and case of adult it is responsible for 10% of acute bacterial pharyngitis.


Epiglottis is the part of the oropharynx and it also forms the back wall of the space which is present below the foundation of the tank. It also helps in the protection of the trachea and larynx from respiration during the act of swallowing. The infection of the epiglottis is caused by the direct involvement of epithelium by a microbial pathogen. The posterior wall of the nasopharynx is initially the source of the bacteria.

Hence epiglottis main causes life-threatening Airway obstruction. In the case of children the symptom of epiglottis Nation in time of few hours in case of children these are the most common symptom of epiglottis which include sore throat loss of voice, fever, etc.


The cause of the occurrence of the lift area is Gram-Positive bacilli Corynebacterium diphtheria. The individual which is infected by Gram-Positive bacilli gains in self-respiratory diseases or infections which is separated in most cases with direct contact with respiratory secretion and also from regions on the front of human skin.

The infection of disease is also separated by cow’s milk. Diphtheria occurs throughout the whole year but more frequently occurs in winter. At the start patient suffer from swelling of the throat and fever with the low-grade patient with an excess of this disease has developed cervical lymph node enlargement and swelling of the neck.

The patient who is suffering from a disease of diphtheria needs treatment at the hospital and also should give antitoxins and an antibiotic against diphtheria. Antitoxin and the first step are used against the treatment of diphtheria. The administration is first of all some antitoxins against the disease of diphtheria without waiting for the result.

In Enslaver case of diphtheria when the patient is unable to breathe normally the administration of the hospital use breathing tubes for the survival of an individual but this kind of step taken in serious extreme hard conditions.


Tracheitis actually in most cases refers to the swelling of the bronchia, trachea, and larynx in most cases effect of tracheitis is caused by bacteria and viruses. The epithelium of the trachea is injured by an excess of smoke. Hence infection of tracheitis affects the patient at any age or infection of the trachea is age-independent.

It is also present in children due to disturbance of the airway of children. The infection of this disease occurs more at the subglottic area because the subglottic area is the closest part of the trachea. In some cases accumulation of mucopurulent fluid take place. The bronchial excess activity may revoke upper respiratory tract infection.

The patient who carry cough for more than 3 weeks they have got excess of symptoms of upper respiratory tract infections. The patient who carries Cup from 3 to 8 weeks is considered this kind of patient carry post-infectious cough. In the case of most patients, a specific agent which is called an etiologic agent could not present.

Complications of upper respiratory tract infection

  • In most cases, respiratory tract diseases resolve totally but in a minor number of cases, complications may emerge. 
  • It has as of late been shown in balanced models controlling for the presence of key infections, microbes, and intense otitis media risk variables that intense otitis media hazard was autonomously associated with tall respiratory syncytial viral stack with pneumoniae and H. influenza. The chance was higher for the nearness of bocavirus and H. influenza together.
  • The conclusion was that intense otitis media hazard contrasted with particular infections and microscopic organisms included which the preventive endeavors ought to consider strategies for diminishing infections caused by RSV, bocavirus, and adenovirus in addition to intense otitis media bacterial pathogens.
  • The bronchial hyperreactivity may be improved or provoked by respiratory tract contaminations. 
  • Patients with persistent obstructive pneumonic infection may to involvement an exacerbation. Patients who have diligent hack enduring for more than 3 weeks after they have got through intense indications of upper respiratory tract contamination, may have a post-infectious hack. 

Prevention of upper respiratory tract infection

Upper respiratory tract infection prevented in many ways some of these are given as:

  •     You should not meet with a person who carries upper respiratory tract infections.
  •     If you are ill with an upper respiratory tract infection then you could not go outside and most remain at your home it is helpful to avoid the upper respiratory tract infection for separating and healthy person.
  •     It is most important that you prevent touching your hand to your face if your hand or unwashed.
  •      Upper respiratory tract infections may also be prevented by the use of tobacco at your home and also at the public place.
  •      If you go to public places then it returns you wash your hands with high-quality soap all the time you use tissue for sneezing.

Treatment options for URTI

Upper respiratory tract contaminations (URIs) are commonly treated in family physicians. Uncomplicated URIs account for 25 million visits to family doctors and approximately 20 to 22 million days of nonattendance from work or school each year within the Joined together States.

  1.  In spite of the larger part of these contaminations being viral, a tall rate is treated with antibiotics.
  2.  Think about from a huge, outpatient mobile arrange of more than 52,000 cases of URI appeared that anti-microbial was endorsed in 65 percent of patients. Abuse of anti-microbial may lead to resistance, expanded taken a toll, and expanded rate of unfavorable impacts, counting anaphylaxis. There is not present any specific treatment for most kinds of viruses. More power in case of treatment of Influenza some medicine or still present in the market.
  3. About 70 to 80% of diseases are caused by the influenza A virus or prevented by some amantadine. Amantadine and rimantadine both of these drugs reduce the severity of the disease and help in the reduction of the disease.
  4. The drug amantadine used in the case of children who are older than 12 months but rimantadine used in the case of children who are above 13. The use of both drugs amantadine and rimantadine have many side effects which is given as they also decrease efficiency in some infections of the Influenza virus. It is considered that both these drugs amantadine and rimantadine are cheaper as compared to Other Drugs which are available in market.
  5. Upper respiratory tract infection or also treated in home with the physical hard working with the support of family members. Upper respiratory tract infections are treated in many ways most of the upper respiratory tract infections or treated with the help of antibiotics and the use of penicillin is also effective in the case of upper respiratory tract infections. Antibiotics used as an antibiotic agents and play an important role against bacteria.
  6. The growth of that bacteria is inhibited by the use of antibiotics are also the reason for any kind of side effects like diarrhea etc.
  7. Penicillium is also used as an anti-microorganism agent. A low concentration of penicillin is effective for upper respiratory tract infections.
  8. Upper respiratory tract infections are also treated by the physical practice which is performed with the help of family members. In most cases of upper respiratory tract infections, the disease is treated with himself at home without any medical treatment

In most cases upper respiratory tract infection or recognized by the symptom and physical examination. Some diseases of upper respiratory tract infection can also be treated at home. Its symptoms are more dangerous in some circumstances as an immunocompromised persons. That person needs medical attention the target is to detect the agent which causes it, it can make us able to sufficient therapy.
