There is currently no specific treatment for<unk>  infection. However, the viral infection is usually cleared to undetectable levels by the immune system. According to the Centers for Disease Control and Prevention, the body's immune system clears<unk>  naturally within two years for 90% of cases (see Clearance subsection in Virology for more detail). However, experts do not agree on whether the virus is eliminated or reduced to undetectable levels, and it is difficult to know when it is contagious. Follow up care is usually recommended and practiced by many health clinics. Follow-up is sometimes not successful because a portion of those treated do not return to be evaluated. In addition to the normal methods of phone calls and mail, text messaging and email can improve the number of people who return for care.
