    Scarlet fever - «purple fever", because at the end of the XVII century
    It called the disease better known as scarlet fever. In past centuries, scarlet fever
    took away thousands of lives during epidemics every third patient died of this
    infection. It was compared with the plague, funds from the scourge existed and
    I could only pray for salvation. Today the situation has changed,
    the incidence decreased significantly, but the infection is still there. AT
    Basically, doctors recorded cases of scarlet fever in children, because the causes and symptoms of scarlet fever should know each

    What is scarlet fever?

    Scarlet fever - an acute infectious disease caused by
    beta-hemolytic streptococcus group A, which is found in angina,
    chronic tonsillitis, streptococcal impetigo, erysipelas skin is
    cause of rheumatic fever and acute glomerulonephritis.

    Streptococci may inhabit the tonsils and the child's skin, but scarlet fever
    It occurs only under favorable conditions when they begin to show
    septic properties, i.e. penetrate into the surrounding tissue tonsils fall
    in the blood and viscera, causing secondary damage and poisoning
    organism. It plays a role allergic factor causing the appearance of
    scarlet rash and the development of complications such as rheumatic fever or vasculitis.

    Where does scarlet fever - the etiology of the disease

    The source of infection is a sick man. Infection
    It occurs through airborne droplets when communicating with patients, singling out
    microbes with saliva droplets when coughing, sneezing and talking. Special
    risk of contact with an infected person in the early days of the disease and
    Over the next 3 weeks. In addition, infection may streptococcus
    dirty hands, household items, kitchenware, toys or clothes.

    "To catch" scarlet fever pathogen can be a healthy
    person who is a carrier of infection. Up to 20% of adults are
    carriers of beta-hemolytic streptococci and it does not have symptoms of scarlet fever.

    The susceptibility of children and adults to toxigenic strains
    A beta-hemolytic streptococcus high. Immunity after myocardial
    tipospetsifichen disease, that is, if a child, a man suffered
    scarlet fever caused by streptococcus distinguishing erythrogenic toxin type A,
    do not interfere with scarlet fever ill again, provided that the new
    pathogen belongs to a different serovar.

    Pathogenesis of scarlet fever

    Scarlet fever is manifested general intoxication, sore throat,
    punctate rash on the body. From there the symptoms of scarlet fever? incubation period
    disease ranges from 1 to 10 days. So much time is necessary to
    Streptococcus began to show toxigenic properties launched in the body of the child
    pathological processes inherent in such diseases as scarlet fever. The incubation period is completed the development of the inflammatory process at the site of penetration
    A beta-hemolytic streptococcus - develops scarlet angina.

    In the process of life pathogen scarlet highlights
    toxins that affect the small blood vessels in the skin and internal
    organs, causing a scarlet rash. Increased and more
    permeability of small blood vessels in the skin accompanied by edema surrounding
    tissues and malnutrition, which leads to the death of cells in the epidermis,
    keratinization and subsequent flaking.

    In response to the introduction of streptococci in the child's body begin
    generated antibodies, which are fixed on the membranes and internal organs
    participate in the development of autoimmune reactions, the basis for such diseases as
    glomerulonephritis, rheumatic fever, endocarditis, arteritis.

    The causative agent of scarlet fever goes from tonsils in regional
    lymph nodes, and collects them in the lymphoid tissue causes inflammation.
    Breakthrough the barrier and the blood rushing, streptococci are spread
    body, it affects various organs and tissues, causing secondary foci of infection,
    eg, purulent otitis, meningitis, lymphadenitis.

    Stop scarlet fever
    It can only be timely treatment. With the development of a child's sore throat,
    a rash on your body, consult your pediatrician for further
    disease diagnosis.
