Most of the children get exposed to hepatitis A virus due to not so good sanitation. Only few of them get hepatitis and rest get sub-clinical infection. Most of them get recovered and get immunity to the infection. Even to day also most of the rural Indian population takes treatment from the unqualified doctors. They get the hepatitis B infection from them. Most of the children recover from the infection and get immunity against the hepatitis B virus infection. Same is true for other strains of the hepatitis viruses.
Children with hepatitis A often exhibit asymptomatic cases due to their generally robust immune response and the mild nature of the virus in younger populations. Their immune systems can effectively manage the infection without triggering severe symptoms, leading to a higher likelihood of asymptomatic cases compared to adults. Additionally, the viral load in children may be lower, resulting in minimal impact on liver function and overall health. Consequently, many children may not exhibit the classic symptoms associated with hepatitis A, such as jaundice or abdominal pain.
If anti-HBs is reactive, it indicates that the person is immune to the hepatitis B virus either due to vaccination or a past infection. This means that the person has developed antibodies against the hepatitis B surface antigen, providing protection against future hepatitis B infections.
Yes, a child can die from chickenpox, but the vast majority of children recover from chickenpox with no long-term effects.
Vaccinations are intended to prevent diseases - they are much less useful if given after exposure to the disease. It makes sense to vaccinate children before they have much chance of exposure. Remember that Hepatitis B & C are not just transmitted sexually, but can also be transmitted by blood contact such as stepping on a used needle. If we have as many people as possible who are immune to Hepatitis B, then there will be less of it in the population and therefore less chance of it being caught by the people who are not immune (such as people who do not react to the vaccine).
A must to work as a dental nurse is to be Hepatitis B immune
Infants born to hepatitis B-infected mothers have a greater-than-95% chance of being protected against the virus if they receive the first dose of vaccine and immune globulin within 12 hours of birth.
The RNA interferences treatments for AIDS, hepatitis and cancer have once thing in common as all tend to boost our immune system.
first Hepatitis A is an acute infectious disease of the liver caused by Hepatitis A (HAV) Hepatitis A does not have a chronic stage, is not progressive, and does not cause permaneHepatitis A does not have a chronic stage, is not progressive, and does not cause permanent liver damage. Following infection, the immune system makes antibodies again liver damage. Following infection, the immune system makes antibodies against HAV that confer immunity against future infection. The disease can be prevented by vaccination and hepatitis A vaccine has been proven effective in controlling outbreaks worldwide.
NO. It would not be advisable. Any form of liver inflammation is called Hepatitis. This inflammation can be caused by drugs, viruses, fatty tissue, heredity or bacteria. Prior alcohol abuse and binge drinking is another of the causes. Auto immune Hepatitis is very similar to Lupus Erythematosus and can severely damage the liver. Auto immune hepatitis results from the bodies own antibody defenses actively attacking the liver. Alcohol would work that already damaged liver unnecessarily. Crohns disease works in much the same way, it is suspected. While a cause is yet unknown, what is known is that Crohns Disease is an inflammation of the digestive tract and can affect other organs. Consumption of alcohol often exacerbates symptoms in the already sensitive bowel by forcing that liver to produce excess bile and releasing it into the bowel. Like putting acid on a wound.
AIDS (Acquired Immune Deficiency Syndrome) is a condition that occurs after someone has been infected with HIV (Human Immunodeficiency Virus.) HIV uses cells associated with immune function for replication and AIDS is not contagious. Hepatitis is a virus that attacks the liver.
HBsAg non-reactive does NOT mean immune to hepatitis B. To understand this we have to discuss what exactly HBsAg is. The hepatitis B virus has several components. It is an encapsulated virus, meaning that its central DNA core is protected by an outer shell. This shell is sometimes called the "surface". On this surface are some antigens, which are simply proteins that induce an immune response in the body. We abbreviate these antigens as HBsAg, which is shorthand for "hepatitis B surface antigen". If a blood test reveals that there are no detectable hepatitis B surface antigens, this simply means that the individual has no evidence of being currently infected with hepatitis B. Otherwise, there would be some hepatitis B surface antigens (with hepatitis B DNA inside them) floating around in the bloodstream. To determine if a person is immune to hepatitis B, we must draw a different test. This test checks for the presence of antibodies to the hepatitis B surface antigens. Sometimes this is abbreviated as HBAb, or as Hepatitis B IgG. If the patient has antibodies to Hepatitis B surface antigens, and has no detectable HBsAg in their bloodstream, then it is likely that they are immune. But be careful! Simply having Hepatitis B surface antibodies does not indicate immunity! It may mean that the person is actually infected with Hep B. This is why both tests are necessary to document immunity.
The weakening of the immune system increases the possibility of acquiring an infectious disease.
