In L. infantum transmission foci, asymptomatic infections and mild clinical forms of VL are indeed frequent in humans [ 12, 13].
Few cases of reported DHF fulfill criterion 3 due to the short duration of severe thrombocytopenia in mild clinical forms (8 ).
Mild clinical forms were common in 20 cases (90.9%), severe forms were determined by the prolonged evolution of the disease and association of neurological complications (polyradiculoneuritis) in 2 cases (9.1%).
In order to determine whether animals with severe clinical disease and animals with a milder clinical form of disease had a different antibody response we compared the two groups using ELISA technique and tested for significant differences.
Although Dengue infection usually manifests itself in its mildest, though often debilitating clinical form, dengue fever, life-threatening complications commonly arise in the form of hemorrhagic shock and encephalitis.
Most of the patients present with mild to moderate clinical forms, but leptospirosis may lead to multiple organ failure and death.
There were no significant differences in the distribution of F and C among asymptomatic, mild, and severe clinical forms of malaria among whole populations from the three study areas collectively, p = 0.297.
Follow-up results from a seronegative cohort demonstrated that none of the persons that seroconverted met the criteria that would define a case of HPS, indicating that mild or asymptomatic clinical forms of the disease developed with greater frequency in those who became infected than did the classic form of HPS.
However, the results of our study suggest that mild sub-clinical forms of radiation hepatitis can be detected by PET/CT earlier; in the two patients in our group who demonstrated increased FDG uptake in the left lobe of the liver 6 weeks after completion of radiation therapy, there were accompanying abnormalities in alkaline phosphatase.
Its course has mostly mild clinical signs.
