What is the structure of hepatitis B virus?
The infectious HBV virion (Dane particle) has a spherical, double-shelled structure 42 nm in diameter, consisting of a lipid envelope containing HBsAg that surrounds an inner nucleocapsid composed of hepatitis B core antigen (HBcAg) complexed with virally encoded polymerase and the viral DNA genome..
Can you get hepatitis B from saliva?
HBV is unlikely to be spread through saliva, but is possible through abrasions or mouth sores that may occur a result of rigorous kissing, bites, or trauma from dental appliances or braces when blood exchange may occur. HBV is not spread by eating food prepared by someone who is infected.
How long can you live with hepatitis B untreated?
The hepatitis B virus can survive outside the body for at least 7 days.
Which hepatitis can become chronic?
Chronic hepatitis is inflammation of the liver that lasts at least 6 months. Common causes include hepatitis B and C viruses and certain drugs. Most people have no symptoms, but some have vague symptoms, such as a general feeling of illness, poor appetite, and fatigue.
What is the best treatment for chronic hepatitis B?
Treatment for chronic hepatitis B may include: Antiviral medications. Several antiviral medications — including entecavir (Baraclude), tenofovir (Viread), lamivudine (Epivir), adefovir (Hepsera) and telbivudine (Tyzeka) — can help fight the virus and slow its ability to damage your liver.
How do I know if I have chronic or acute hepatitis B?
If you test positive for HBsAg for longer than six months, it means you have a chronic hepatitis B infection. But, if you no longer test positive (or “reactive”) for HBsAg after six months and you develop hepatitis B surface antibodies (HBsAb), then you have cleared hepatitis B after an “acute” infection.
Which Hepatitis does not cause chronic hepatitis?
Hepatitis A: According to the Centers for Disease Control and Prevention, there were about 2,007 instances of acute hepatitis A infections in the U.S. in 2016. This form of hepatitis does not lead to a chronic infection and usually has no complications. The liver usually heals from hepatitis A within several months.
Which hepatitis is not curable?

Can chronic hepatitis B be cleared?
Most people are able to clear hep B from the body within six months of becoming infected. If they clear it, they are no longer infected, nor can they infect others. Additionally, they now have hepatitis B antibodies, which will protect them from future reinfection.
Can you get hepatitis B from a toilet seat?
Hepatitis B is NOT transmitted casually. It cannot be spread through toilet seats, doorknobs, sneezing, coughing, hugging or eating meals with someone who is infected with hepatitis B.
What happens if you are not immune to hepatitis B?
Persons exposed to HBsAg-positive blood or body fluids who are known not to have responded to a primary vaccine series should receive a single dose of hepatitis B immunoglobulin (HBIG) and restart the hepatitis B vaccine series with the first dose of the hepatitis B vaccine as soon as possible after exposure.
What does it mean if you are not immune to hepatitis B?
A hepatitis B vaccine “non-responder” refers to a person who does not develop protective surface antibodies after completing two full series of the hepatitis B vaccine and for whom an acute or chronic hepatitis B infection has been ruled out.
What do chronic hepatitis infections result in?
For some people, hepatitis B infection becomes chronic, meaning it lasts more than six months. Having chronic hepatitis B increases your risk of developing liver failure, liver cancer or cirrhosis — a condition that permanently scars of the liver.
Does Soap kill hepatitis B?
Due to soaps’ molecular makeup, a drop of any ordinary soap in water is potent enough to rupture, dislodge or kill many types of bacteria and viruses, including the new coronavirus, HIV, hepatitis B and C, herpes, Ebola, dengue and many other bacteria that attack the intestines and respiratory tract.
How long is hepatitis B contagious?
