Observation over

Observation over dynamics of clinical semiology during flu epidemics has shown, that in the beginning of epidemic the flu proceeds more hardly, with typical clinical implications, and in the end of epidemic the easy forms of illness reminding on clinical picture of other aetiology start to prevail, and to carry out differential diagnostics begins more difficultly. order ultram 1mg In epidemic beginning the clinical semiology allows to allocate a flu from among other respiratory diseases. Illness begins acutely, the body temperature with a fever already in the first days reaches a maximum level (39... 40 °). The headache with localisation in frontal area, arches is sharply expressed. Only for a flu the pain in eyeballs (retroorbital) which appears at movement by eyes is characteristic, at pressing on eyeballs. The dacryagogue and a photophobia also are observed at a flu, but they can be and at others . Only at a flu strong pains in muscles of all body become perceptible. At others ( diseases, the parainfluenza and so forth), even in the presence of a high fever, muscular pains does not happen. The general intoxication is shown also in an adynamia, the raised sweating, depression of arterial pressure. At a high fever and sharply expressed toxicosis the boring of cerebral covers (a meningism, entsefalopat1/I) can be observed.
For differential diagnostics that the fever at a flu in overwhelming majority of cases (85 %) does not proceed more than 2 is very important... 4 days. If the fever remains over 5 days it not the flu or begins any complication of a flu (a pneumonia, etc.). From the flu differs first of all more expressed implications of the general intoxication and that it proceeds in the form of epidemics grasping many countries, and even pandemics, especially if there is a new antigenic variant of a virus of a flu And.
Gravity of disease at circulation of various strains of a virus of a flu, hour complication at different epidemic flashes essentially differ. The first patients at flu epidemic offensive can already be as though the standard on which it is possible to judge features of a flu in the river this concrete epidemic flash.
For a flu most typical presence of the expressed tracheitis. This place of the strongest inflammatory process. At sick the flu becomes perceptible change and other departments of a respiratory tract (a rhinitis, a pharyngitis, a laryngitis). Whereas the tracheitis is very poor clinical implications, and symptoms of a rhinitis, a pharyngitis and a laryngitis at some patients are expressed weakly, in such cases the diagnosis flu forms is quite often established. Actually such form of illness not . It is important for vpxl 1mg differential diagnostics. At a flu always to find, let even weakly expressed, inflammatory changes of mucosas of respiratory tracts, first of all a tracheitis. It is especially important for difference of a flu from so-called forms of other infectious diseases (an ornithosis, a salmonellosis, etc.).
In interepidemic on a flu time flu viruses in structure of case rate take very small place, making I..... 5 % from all case rate acute respiratory illnesses. Hence, at this time the probability of a flu is very insignificant. Besides, during interepidemic time the clinical semiology of a flu essentially varies. Diseases proceed mainly in the easy form with weakly expressed intoxication, there are no such important implications, as muscular pains, 5 in eyeballs, the high fever, the raised sweating. The clinical picture of a flu during this period as though approaches with semiology of other aetiology. During the interepidemic period reliably to differentiate a flu from others it is possible only on the basis of datas of laboratory. However a small specific gravity of a flu among others in time usually constrains carrying out of similar researches.
Laboratory acknowledgement of a flu probably by virus detection in slime of a fauces and a nose by means of a method of fluorescent antibodies. This method is suitable for express diagnostics as the answer can be received in some hours. Serologichesky methods can be used only for retrospective diagnostics as it is necessary to investigate : Serums (the first take till 6th day of the illness, the second - later 10... 14 days). By this time all implications of a flu already pass also researches often have only scientific value. Carry out such researches at atypical forms of a flu. Basically flu diagnostics remains clinical.
