A cross-sectional study of 540 married Akha and Lisaw women of reproductive age was conducted in Chiang Rai Province, Thailand, between June 1st and August 31st, 1999, in order to determine the seroprevalence of HBsAg and identify the risk factors for chronic HBsAg carriage. HBsAg was detected by the reverse passive hemagglutination technique (RPHA). Data were obtained by questionnaires and serological testing. There were 164 Lisaws and 376 Akhas: most were illiterate (88.71%) and the annual family income was < or = 9,999 baht (50.93%). The seroprevalence of HBsAg was 8.15%. Logistic regression analysis, controlling for possible confounding factors, revealed that one to five injections in the year prior to the study increased the risk of HBsAg carriage by a factor of 4.84 (95% CI = 1.42-16.49); more than six injections increased the risk by a factor of 5.84 (95% CI = 1.47-23.18).

Hepatitis

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...

Viral Hepatitis I: Introduction

Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
Trichomoniasis01:18

Trichomoniasis

Trichomonas vaginalis is a flagellated protozoan parasite and the causative agent of trichomoniasis, one of the most prevalent non-viral sexually transmitted infections in the United States. This extracellular parasite primarily colonizes the lower genitourinary tract in women—particularly the vagina—and in men, the urethra and prostate. Its structural and functional adaptations enable its survival, motility, and pathogenicity within the host environment.Structural Features and Host EntryT.
