Could it be pneumonia without fever
Pneumonia (a pneumonia) is an inflammatory disease that affects the lung tissue. According to the world health organization at the global level, this disease is the third leading cause of death, high mortality from this disease was, especially in developing countries. In our country every year, according to experts, the incidence of over 100,000 cases.
Because the disease is quite relevant, a considerable number of people interested in the question regarding his symptoms, in particular, is whether pneumonia without fever, what are the specific symptoms of pneumonia without fever, can have pneumonia without fever and other symptoms is more dangerous than the classic?
Increased risk of pneumonia is present in people weakened by other serious diseases (e.g. cancer, disease, etc.). A higher incidence of pneumonia observed in the groups of smokers, alcoholics and drug addicts. As a rule, the more frequent is pneumonia contagious in children rarely occurs in adults, in a group of people over fifty years of age incidence curve rises again.
The disease can be classified from different points of view. Based on the time course of inflammation acute and chronic illness. According to the lung – unilateral or bilateral pneumonia. In accordance with the origin distinguish pneumonia and infectious to non-infectious.
Regardless of the causative agent and the origin, inflammatory pulmonary process able be able to exist without showing any special sign. In this case, there is a pneumonia with no symptoms (ie, pneumonia without fever and cough, because it is less noticeable symptoms still present). This disease is, to some extent, can be considered more dangerous than a classic form of the disease, because people are often not aware of the presence of infection in the body, referring to the usual fatigue. Symptoms of pneumonia without fever include weakness, perhaps, headache, General malaise. Cough is usually absent.
Pneumonia without fever occurs most often in the case of immunodeficiency. Also, there are cases of this type of uncontrolled disease after receiving drugs from the group of antibiotics.
Pneumonia without fever and no cough is a threat to humans, because when coughing is derived from the body sputum and, with it, an adverse microorganisms. Temperature, in turn, warns of the presence of an infection. In the absence of manifestations of the disease, the person may not even know about the problem, moreover, all the pathogens remain in the body because he can't get rid of them by coughing.
Types of pneumonia
The basis of non-infectious pneumonia can include, for example, in the inhalation (aspiration) of stomach contents or other pollutant, in this case, refers to aspiration pneumonia. Aspiration of gastric contents frequently occurs when a person is unconscious or in a state of alcoholic intoxication.
To the penetration of the contents of the gastrointestinal tract into the respiratory system may be reached in the case of some developmental disorders. For example, if there is abnormal connection between the esophagus and the trachea, in case of untimely detection of these defects can for example cause of pneumonia in children of early age. Lung tissue damaged by the acidic pH of the gastric contents, as well as bacteria that are in food.
In addition to the contents of the gastrointestinal tract, aspiration pneumonia can also be caused by, among other things, inhalation of a foreign body, there are cases "of the disease of fire-eaters" when it comes to unintentional aspiration of kerosene. In a typical clinical picture is present are symptoms of aspiration pneumonia, as acute shortness of breath and cyanosis (ie, blue-purple tone of the skin and mucous membranes) may be added, and the temperature. However, the disease can occur even in secret, with a dry or productive cough, without high temperature.
A source of non-infectious inflammation of the lungs may be breathing in toxic fumes, gases or hot air, this state is described as inhalation pneumonia. Inhalation of contaminants often occurs in connection with accidentsindustrial production, in case of fire, etc. This condition is usually in the acute phase reflects the irritating coughing, sneezing, shortness of breath, cyanosis. When the first aid in this case, it is especially important the safe transport of the victim from contaminated area to fresh air.
The cause of infectious pneumonia are primarily respiratory pathogens. In our environment is the most common bacterial or viral pneumonia, but perhaps even presence as agents of some parasitic or fungal agents of inflammation.
In everyday life, as a rule, there are streptococcal infection, staphylococcal, can also be the causative agent Haemophilus coli, some species of chlamydia or Mycoplasma, Klebsiella, Legionella and other bacteria, as well as a number of viruses.
In contrast to non-infectious inflammation, people with infectious pneumonia is contagious, especially in the acute phase of respiratory infections, from the point of view of infection in the environment is insecure also incubation period.
Pneumonia, mainly, is based on infections caused by bacterial or viral agents, less often, parasites and fungi. Despite the fact that it was identified more than 100 strains of infectious agents, in most cases, the disease may cause only a few of them. Mixed infection caused by bacteria and viruses, there are, approximately, 45% of diseases in children and 15% of diseases in adults. The cause of the disease cannot be determined, approximately 50% of cases despite thorough diagnosis and examination.
The term pneumonia is sometimes more broadly, refer to any disease that causes inflammation of the lungs (caused, in particular, autoimmune disorders chemical burns or medications). These types of inflammation, belong to a different category – pneumonitis. Infectious agents in the past, based on the supposed manifestations were subdivided into typical and atypical, but the evidence did not support this distinction and, therefore, this classification is no longer used.
Disorders and risk factors that can cause susceptibility to pneumonia include Smoking, immunosuppression, alcoholism, chronic renal and hepatic diseases, chronic obstructive pulmonary disease. The use of drugs that suppress stomach acid, such as H2 receptor blockers or proton pump inhibitors, are also associated with an increased risk of developing the disease, similarly as getting older.
Bacteria represent the most frequent causative agent of community-acquired pneumonia. Almost 50% of cases, illness is caused by Streptococcus pneumoniae. Other commonly isolated bacteria include Haemophilus influenzae infection (20%), Chlamydophila pneumonia (13%) and Mycoplasma pneumonia (3%), other agents are Staphylococcus aureus, Legionella and gram-negative bacilli. However, increasingly, there are drug-resistant variants of the above bacteria, including drug-resistant Streptococcus pneumoniae and methicillin-resistant Staphylococcus aureus.
Viruses are the causative agent in adults, about 1/3 and in children for about 15% of cases of pneumonia. Usual pathogens include rhinoviruses, coronaviruses, influenza virus, RSV, parainfluenza virus, and adenovirus. HPV is the causative agent of the disease is rare except in newborns, people suffering from cancer who have had organ transplants and people with severe burns. People, after organ transplantation or those who are suffering from lower immunity, higher risk of pneumonia caused by cytomegalovirus. Individuals who suffer from viral infections may be secondarily infected with pneumococcus, Staphylococcus, or Haemophilus infection, especially in the case of related health problems. At any time of the year is dominated by other viruses – for example, during flu season, the flu virus can cause more than half of the cases of viral pneumonia. Sometimes this disease can be caused by other viruses, such as Hantaviruses, and coronaviruses.
Treatment of pneumonia depends on the cause and severity. Standard in the treatment of pneumonia, especially, is represented by the introduction of antibiotics, are also suitable medication to reduce fever, cough, etc.
