D. Modes of Transmission Hepatitis D is usually spread though exposure to blood or serous fluids, often by contaminated needles or syringes, or by use of contaminated plasma derivatives such as clotting factor. Your disease may remain in this incubation period for a long time, anywhere from 2 weeks to 6 months. An infected person is still highly contagious even without the presence of symptoms.

This manual answers commonly asked questions regarding the surveillance and reporting of vaccine-preventable diseases and provides information on enhancing existing surveillance systems. Krugman. E. Incubation Period The incubation period for hepatitis A ranges from 15 to 50 days, with an average of 28 to 30 days. An individual infected with HBV should be considered infectious any time hepatitis B surface antigen (HBsAg) is present in the blood. The range is 2 to 9 weeks; mean incubation period is around 6 weeks but has varied from 26 to 42 days in different epidemics. It can cause serious symptoms that can lead to lifelong liver damage and even death. Discusses all aspects of viral hepatitis, from structure and molecular virology, and natural history and experimental models, to epidemiology, diagnosis and prevention. Hepatitis C. Hepatitis C is transmitted through exposure to body fluids containing the hepatitis C virus (HCV). Chronic infection can occur in up to 70% of individuals while up to 30% will spontaneously resolve their infection. E. Incubation period. Symptoms may develop over a period of 3 months (incubation period) but once evident can last for between 2 and 12 weeks. A, nonB hepatitis suggests that the incubation period is variable, usually longer than hepatitis A and shorter than hepatitis B, with a mean of 10.5 weeks. If the fever is of short duration, leukopenia may be the only other sign, but if it persists for >1 day, acute illness develops.

Incubation Period In those people who do develop symptoms, the average period from exposure to symptom onset is 2–12 weeks (range: 2–26 weeks). F. Period of communicability All persons with detectable HDV RNA in their blood are potentially infectious to others. How long the incubation period lasts is dependent on the number of virus particles a person is exposed to. TREATMENT MEDICATIONS Antiviral monotherapy Severe acute hepatitis, pre-existing liver disease, concomitant hepatitis C/D infection, immunocompromised, elderly Acute hepatitis Post-exposure prophylaxis HBV vaccine and immunoglobulin Chronic hepatitis Combination therapy (e.g. Peak infectivity probably occurs just prior to onset of acute illness, when particles containing delta antigen are readily detected in the blood.
