Objective To assess oral health knowledge and behaviors of self-care among HIV infected patients in Yunnan, China. Methods Questionnaire survey was performed to collect the information about behaviors of oral self-care and seeking medical advice and diets of 216 HIV-infected patients who came from the Third Hospital of Kunming. The data were then statistically analyzed. Results Half of the patients were diagnosed over six months. The smoking of the HIV-positive were serious and the gingival bleeding was less, but there was obvious discomfort in oral cavity when eating. In addition,the standard method of cleaning teeth was below 20%, less of 50%patients could clean the oral cavity in time after diet and they didn't replace their toothbrushes timely. Over half of patients asked artificial tooth and exodontias on treatment. Conclusion It is necessary to pay more attention to the oral health knowledge and self-care behaviors of HIV-infected patients so as to improve the quality of life.

OBJECTIVETo determine the incidence of human herpes virus (HHV) 1-4 type including herpes simplex virus type-1 (HSV-1), herpes simplex virus type-2 (HSV-2), varicella-zoster virus (VZV), Epstein-Barr virus(EBV) in the saliva of human immunodeficiency virus (HIV) -infected patients.

METHODSThe incidence of salivary HSV-1, HSV-2, VZV and EBV from 245 HIV-seropositive individuals and control group was used to investigate by polymerase chain reaction(PCR) or nested PCR. The data was analyzed by SPSS 18.0 statistical software.

RESULTSIn the 245 HIV-seropositive individuals, the detection rates of HSV-1, HSV-2, VZV, EBV were 29.0%, 3.3%, 4.1%, 82.0%. In the control group, the detection rates of HSV-1, HSV-2, VZV, EBV were 13.3%, 0, 0, 36.7%. Four HHVs were significantly more prevalent in the salivas of HIV-seropositive persons than those in the control group (P < 0.01). The detection rates of HSV-1, HSV-2, VZV and EBV DNA were no difference between the HIV-positive group with highly active antiretroviral therapy (HAART) and HIV-positive group without HAART (P > 0.05).

CONCLUSIONThere is a high prevalence of HHV infection in HIV-infected people in Yunnan. The most common virus are EBV, followed by HSV-1, but VZV and HSV-2 are rarely detected. HHV co-infection is also observed.
