Things to note when the hepatitis A antibody is negative

Liver disease is one of the more prevalent diseases in life. The harm caused by liver disease is very serious. Usually, it can bring great pain to the patient's body. When the disease occurs, there will be abnormal pain in the liver area, etc. There are many types of liver disease, among which hepatitis A is a more popular one. People who have hepatitis A antibodies in their bodies should not relax. Let's take a look at what are the precautions for negative hepatitis A antibodies?

In fact, people with negative hepatitis A antibodies have no immunity to hepatitis A and are called susceptible people. The same is true for hepatitis C antibodies. Hepatitis A, a highly contagious viral hepatitis, often occurs in cyclical epidemics. Usually after an epidemic, the number of people with negative hepatitis A antibodies in the population decreases significantly, but after several years, the number of susceptible people increases, creating conditions for another epidemic of hepatitis A.

Statistics show that people with negative hepatitis A antibodies have a very high chance of being infected with hepatitis A. Therefore, this group of people must go to the hospital in time to get the hepatitis A vaccine. When the hepatitis A antibody is positive, it can effectively prevent the invasion of the hepatitis A virus.

The susceptible population for hepatitis A is those with negative hepatitis A antibodies. The younger the age, the lower the positive rate and the more people with negative hepatitis A antibodies, so hepatitis A is more common in children and young people. After an epidemic of hepatitis A, the number of people with negative hepatitis A antibodies in the population decreases significantly, but several years later, the number of susceptible people increases, creating conditions for another epidemic of hepatitis A. Therefore, hepatitis A epidemics are often cyclical.

There is no danger if you are negative for hepatitis A. At that time, people with negative hepatitis A antibodies should not eat raw seafood. Seafood grown in shallow seas is easily polluted by the seawater in which they grow, which may contain hepatitis A virus excreted by hepatitis A patients. If the seafood is not processed and eaten raw, the risk of contracting hepatitis A will be relatively high. Because the hepatitis A antibody is negative, it means that there is no antibody in the body that can fight the hepatitis A virus, it is very easy to be infected with the hepatitis A virus.

Anti-IgG antibodies appear later but last longer and are often negative in the early stages of infection. They are often used in epidemiological surveys. A positive anti-IgM antibody can be diagnosed as hepatitis A. If a low titer is detected, the test should be repeated every 2 weeks, but attention should be paid to false positives caused by rheumatic factors. A positive anti-IgG antibody test indicates a history of hepatitis A infection, but a more than 4-fold increase in the titer of double anti-IgG antibodies also has diagnostic significance.
