| Drug treatment programs should screen all patients for immunity to hepatitis B. Routine screening for hepatitis D is not indicated in persons who are HBsAg positive but asymptomatic. However, the following screening and prevention procedures may be appropriate:<ref>Center for Substance Abuse Treatment. Screening for Infectious Diseases Among Substance Abusers. Rockville (MD): Substance Abuse and Mental Health Services Administration (US); 1993. (Treatment Improvement Protocol (TIP) Series, No. 6.) Chapter 15 - Viral Hepatitis D.</ref>

| *Patients known to be [[HBsAg]] positive who have acute or chronic hepatitis may be tested for [[hepatitis D]]. The followup care and counseling, however, of a person co-infected with hepatitis D is not different from that of a person who is HBsAg positive. Therefore, knowing if the patient is co-infected with hepatitis D is of limited clinical significance.
| |
| *Patients with acute hepatitis B who are not yet HBsAg positive, but are [[immunoglobulin M]] (IgM) hepatitis B core antibody ([[anti-HBc]]) positive, may be tested for HDV; however, again, the presence of HDV antibody will not alter the care or counseling of such a patient.
| |
| *Patients who are HBsAg positive and/or HDV antibody positive should be advised not to share razors, toilet articles, or drinking and eating utensils.
| |
| *Patients who are not already immune to [[hepatitis B]] virus should be vaccinated against the virus.
| |
| *Screening is not necessary in the general population at no risk for HBV or HDV.
