  Information About Hepatitis Investigation
Hepatitis Investigation: Hepatitis B Virus (HBV)

Hepatitis Investigation: Hepatitis B

The Los Angeles County Department of Public Health (LACDPH) is investigating viral hepatitis infections in people who received intravenous medication (injection of medications into the vein) while receiving procedures at the Advanced Pain Treatment Center in San Pedro, California between January 16, 2006 and August 18, 2010. LACDPH recommends that patients who received intravenous medication at this clinic during that time to contact their primary care physicians or health care providers to get tested for hepatitis B and hepatitis C and HIV. LACDPH is notifying these people and their primary physicians or healthcare providers (based on their medical records at this clinic). If you were a patient at this clinic who received intravenous medication between January 16, 2006 and August 18, 2010 and did not receive a letter from LACDPH, call 213-240-7941 to verify you are on the patient list.

If you received intravenous medication at this clinic between January 16, 2006 and August 18, 2010, we recommend that you get tested for hepatitis B and hepatitis C as a precaution, even though the risk that you got infected at the time of your procedure is low. The hepatitis B and C test is a blood test. If you do test positive there are treatments available. We recommend that you be evaluated and tested by your regular healthcare provider (HCP) because he/she will know your health history and provide complete care. If you are known to have been previously infected with HBV, HCV or HIV, testing for that specific virus is not necessary. In this situations, testing for the other viruses should still be done. We have provided a letter give to your HCP when he/she does your testing (or wherever you are tested) as the letter tells the HCP exactly what tests we recommend. If you test positive for HBV, HCV or HIV, it will be important for your HCP to report your infection to the LACDPH and to provide appropriate counseling and treatment.

Call your HCP for evaluation, testing and questions. Only if you do not have health insurance see the clinics listed below for evaluation and testing at a low or no cost.

Hepatitis B Virus (HBV)

Hepatitis B is a serious liver disease caused by the hepatitis B virus (germ). The virus enters the blood stream, attacks the liver, causes illness and may even cause death. Hepatitis B can cause either short-term (acute) or long-term (chronic) infection. Acute ion ranges from asymptomatic or mild disease to--rarely--fulminant hepatitis. Disease is more severe among adults aged >60 years. Approximately 95% of adults recover completely from HBV infection and do not become chronically infected.

The signs and symptoms of HBV infection vary by age. Most children under age 5 years and newly infected immunosuppressed adults are asymptomatic, whereas 30%__50% of persons aged > 5 years have initial signs and symptoms. When present, signs and symptoms can include

  • Fever
  • Fatigue           
  • Loss of appetite
  • Nausea
  • Vomiting
  • Abdominal pain
  • Dark urine
  • Clay-colored bowel movements
  • Joint pain
  • Jaundice

Persons with chronic HBV infection might be asymptomatic, have no evidence of liver disease, or have a spectrum of disease ranging from chronic hepatitis to cirrhosis or hepatocellular carcinoma (a type of liver cancer).

Symptoms begin an average of 90 days (range: a60--150 days) after exposure to HBV. They typically last for several weeks but can persist for up to 6 months.
