How to determine the etiology of upper respiratory tract infection according to the original primary data.
1, in terms of morbidity, 85-90% of the virus, bacteria is probably less than 10%, in addition, mycoplasma and other can also cause;
2, bacteria: poisoning symptoms are heavy, the spirit is still bad after the fever subsides; virus: poisoning symptoms are light, the spirit is as normal after the fever subsides;
3.Bacteria: Most of the cases are of the tachyphylaxis type (body temperature goes up and down); viruses: Most of the cases are of the retention fever type (body temperature remains high);
4.Tonsils with pus, bacteria; tonsils with herpes, follicles, virus;
5.Tonsillar congestion, uneven surface, dark, bacteria; tonsillar congestion, smooth surface, bright color, virus;
6, with khat symptoms (clear snot), viral; with pus snot, purulent discharge, bacterial;
7, viral infection often accompanied by skin, the
8, small age group (infants and children), more bacteria; large age group, more viruses;
9, upper sensation > 3 to 5 days, more combined with bacterial infection;
10, clear snot, thin sputum, mostly viral infections, but some people believe that a few of them are bacillary infections;
11, cough sputum, mostly bacteria; cough sputum less, mostly viruses;
12, Chinese medicine believes: clear sputum (snot) is cold, yellow (pus) sputum (snot) is hot, modern medicine believes from another side: the former is a viral infection, but there are exceptions, a small number of bacilli, the latter is a bacterial infection;
13, blood picture: the initial stage of viral infection: WBC can be mildly elevated, but N more than not high. Bacteria: generally both are high, but there are three cases.
A, WBC is elevated, N is not high;
B, WBC normal/slightly low, N elevated —– mostly negative bacteria;
C, WBC elevated, N elevated —– more positive bacteria.
Classification is more meaningful than the total number.
14, machine check blood WBC classification and manual difference, should be manual for more accurate;
15, fever with chills, may be bacterial infection;
16, fever with cold hands and feet, may be negative bacterial infection (gram stain negative bacterial sepsis, be alert to shock);
17, in the symptoms, signs and symptoms are not typical, and the blood picture and the “four not like”, should be combined with CRP, NALP and other tests comprehensive analysis.
