Abstract: The result of investgation showed that the patients with different course and different phase of the disease and different clinical manifestation varied from serum specific IgG antibody -GMT.As following prolongation of the course and dhase of the disease, having exasperate, the level of GMT- antibody has graduatdolly g rising.This phenomenna could be explained by the situation of the Humoral-immuno reaction correlated.to severity of the disease, especially to different clinlcal features. Among normal population in the local the latent infection rate of EHF is lower, therefore, the GMT is also lower.In general speaking, the patient, whose serum titter of specific IgG antibody is in 1:320,and associated with their clinical manifestations , could be diagnosed. Early There was no obvious difsirence in latent infection in the population before anp later in prevalence, and no relationship between prevalence and ABO blood type was found.
