Get to know Hepatitis B


What is hepatitis B?

Hepatitis B is a virus that infects the liver. Most adults who get hepatitis B have it for a short time and then get better. This is called acute hepatitis B.
You can have hepatitis B and not know it. You may not have symptoms. If you do, they can make you feel like you have the flu. But as long as you have the virus, you can spread it to others.
Sometimes the virus causes a long-term infection, called chronic hepatitis B. Over time, it can damage your liver. Babies and young children infected with the virus are more likely to get chronic hepatitis B.

What causes hepatitis B?

Hepatitis B is caused by the hepatitis B virus. It is spread through contact with theblood and body fluids of an infected person.
You may get hepatitis B if you:
  • Have sex with an infected person without using a condom.
  • Share needles (used for injecting drugs) with an infected person.
  • Get a tattoo or piercing with tools that were not cleaned well.
  • Share personal items like razors or toothbrushes with an infected person.
A mother who has the virus can pass it to her baby during delivery. If you arepregnant and think you may have been exposed to hepatitis B, get tested. If you have the virus, your baby can get shots to help prevent infection with the virus.
You cannot get hepatitis B from casual contact such as hugging, kissing, sneezing, coughing, or sharing food or drinks.

What are the symptoms?

Many people with hepatitis B do not know they have it, because they do not have symptoms. If you do have symptoms, you may just feel like you have the flu. Symptoms include:
Most people with chronic hepatitis B have no symptoms.

How is hepatitis B diagnosed?

A simple blood test can tell your doctor if you have the hepatitis B virus now or if you had it in the past. Your doctor also may be able to tell if you have had the vaccine to prevent the virus.
If your doctor thinks you may have liver damage from hepatitis B, he or she may use a needle to take a tiny sample of your liver for testing. This is called a liver biopsy.

How is it treated?

In most cases, hepatitis B goes away on its own. You can relieve your symptoms at home by resting, eating healthy foods, drinking plenty of water, and avoiding alcohol and drugs. Also, find out from your doctor what medicines and herbal products to avoid, because some can make liver damage caused by hepatitis B worse.
Treatment for chronic hepatitis B depends on whether your infection is getting worse and whether you have liver damage. Most people with chronic hepatitis B can live active, full lives by taking good care of themselves and getting regular checkups. There are medicines for chronic hepatitis B, but they may not be right for everyone. Work with your doctor to decide whether medicine is the right treatment for you.
Sometimes, chronic hepatitis B can lead to severe liver damage. If this happens, you may need a liver transplant.

Can hepatitis B be prevented?

The hepatitis B vaccine is the best way to prevent infection. The vaccine is a series of 3 or 4 shots. Adults at risk and all babies, children, and teenagers should be vaccinated.
A combination vaccine (Twinrix) that protects against both hepatitis B and hepatitis A also is available.
To avoid getting or spreading the virus to others:
  • Use a condom when you have sex.
  • Do not share needles.
  • Wear latex or plastic gloves if you have to touch blood.
  • Do not share toothbrushes or razors.

THE CLASSIC STAGES OF CLINICAL INFECTIONS

As the body of the host responds to the invasive and toxigenic activities of a parasite, it passes through four distinct phases of infection and disease: the incubation period, the prodromium, the period of invasive, and the convalescent period.             The incubation period the time form initial contact with the infectious agent to the appearance of the first symptoms. During the incubation period, the agent is multiplying at the portal of entry but has not yet caused enough damage to elicit symptoms. Although this period is relatively well defined and predictable for each microorganism, it does vary according to host resistance, degree of virulence, and distance between the target organ and the portal of entry (the farther apart, the longer the incubation period). Overall, an incubation period can range from several hours in pneumonic plaque to several years in leprosy. The majority of infections, however,...

Blood types chart

Blood is the river of life, which courses through our bodies. It is the medium through which nutrients and oxygen are transported to each and every part of the body and waste is taken out. It also functions as the defense mechanism, through antigen mechanism present in red blood cells and the white blood cells. When blood transfusion, that is blood transfer from one man to another, was attempted, it was discovered that there are blood types! You cannot randomly transfer blood from one man to another without checking if their blood types match. This article explains why it's important to have a blood type test and how a blood group is determined. A ready reference in the form of a blood types chart has been provided, which indicates blood transfusion compatibility. How is a Blood Type Determined? Why are there blood types? How is a blood type determined? Before we talk about a blood types chart, let us find answers to these questions. To understand why there are  blood types ...

The ELISA

ELISA is stand for Enzyme-linked immunosorbent assay. It is an immunological or serological test to check antigen present in the serum. It have 2 types Direct ELISA or Sandwich ELISA Test and Indirect ELISA test. For Direct ELISA test, it is used to diagnose various microbial infections (such as HIV, Hepatitis A and C, Cholera Vibrio, Helicobacter pylori,...), cancer and other immunological disorders. Different from Direct ELISA, Indirect ELISA is used to diagnosed Hantavirus, rubella virus, toxoplasma.... Procedure of Sandwich ELISA Pour known antigen of specific antibodies on well containing micro titer plate and wait for 2-3 hours or over night then wash with buffer to remove unbound antibodies.  Add patient serum specimen on the well and wait for 1-2 hours and then wash with buffer.  Add Enzyme labelled (linked or conjugated) antibodies on the well and wash with buffer.  Finally, add the substrate (colorless substance) on the well and wait for 1-2 hours to obs...
