What Are The Common Types Of Viral Hepatitis
Although the most common types of viral hepatitis are HAV, HBV, and HCV, some clinicians had previously considered the acute and chronic phases of hepatic infections as “types” of viral hepatitis. HAV was considered to be acute viral hepatitis because the HAV infections seldom caused permanent liver damage that led to hepatic failure. HBV and HCV produced chronic viral hepatitis. However, these terms are outdated and not currently used as frequently because all of the viruses that cause hepatitis may have acute phase symptoms . Prevention techniques and vaccinations have markedly reduced the current incidence of common viral hepatitis infections however, there remains a population of about 1 to 2 million people in the U.S. with chronic HBV, and about 3.5 million with chronic HCV according to the CDC. Statistics are incomplete for determining how many new infections occur each year the CDC documented infections but then goes on to estimate the actual numbers by further estimating the number of unreported infections .
Types D, E, and G Hepatitis
Individuals who already have chronic HBV infection can acquire HDV infection at the same time as they acquire the HBV infection, or at a later time. Those with chronic hepatitis due to HBV and HDV develop cirrhosis rapidly. Moreover, the combination of HDV and HBV virus infection is very difficult to treat.
Living With Hepatitis C
Coping with hepatitis C isnt easy. You may feel sad, scared, or angry. You may not believe you have the disease. These feelings are normal, but they shouldnt keep you from living your daily life. If they do or if they last a long time you may be suffering from depression. People who are depressed have most or all of the following symptoms nearly every day, all day, for 2 weeks or longer:
- Feeling sad, hopeless and having frequent crying spells.
- Losing interest or pleasure in things you used to enjoy .
- Feeling guilty, helpless, or worthless.
- Thinking about death or suicide.
- Sleeping too much or having problems sleeping.
- Loss of appetite and unintended weight loss or gain.
- Feeling very tired all the time.
- Having trouble paying attention and making decisions.
- Having aches and pains that dont get better with treatment.
- Feeling restless, irritated, and easily annoyed.
Talk to your doctor if you notice any of these symptoms. Your doctor can help by recommending a support group or a therapist. He or she may also prescribe a medicine for you to take.
Sometimes The Infection Goes Away On Its Own
Acute hepatitis is C is a short-term illness that occurs within the first six months after being exposed to the virus. Like the human papillomavirus , early acute hepatitis C can clear on its own without treatment this happens about 25% of the time.
However, it’s more likely that the virus will remain in your body longer than six months, at which point it’s considered to be chronic hepatitis C infection.
“Being younger or a woman tends to be a factor in whether the virus clears on its own, and genetics may play a role,” Reau says. “But we can’t determine with certainty which people are certain to clear the infection and which aren’t.”

What Do I Need To Know About Having Hepatitis B
If you have chronic hepatitis B, getting the right medical care can help you stay healthy. Taking good care of your liver is important. Talk with your doctor before you take any prescription medication, over-the-counter drugs, vitamins, or nutritional supplements to make sure they wont hurt your liver. You should also stay away from alcohol, because drinking can damage your liver.
How Common Is Hepatitis C In The United States
In the United States, hepatitis C is the most common chronic viral infection found in blood and spread through contact with blood.14
Researchers estimate that about 2.7 million to 3.9 million people in the United States have chronic hepatitis C.13 Many people who have hepatitis C dont have symptoms and dont know they have this infection.
New screening efforts and more effective hepatitis C treatments are helping doctors identify and cure more people with the disease. With more screening and treatment, hepatitis C may become less common in the future. Researchers estimate that hepatitis C could be a rare disease in the United States by 2036.17

What Is Acute Fulminant Hepatitis
Rarely, individuals with acute infections with HAV and HBV develop severe inflammation, and the liver fails . These patients are extremely ill with the symptoms of acute hepatitis already described and the additional problems of confusion or coma , as well as bruising or bleeding . In fact, up to 80% of people with acute fulminant hepatitis can die within days to weeks therefore, it is fortunate that acute fulminant hepatitis is rare. For example, less than 0.5% of adults with acute infection with HBV will develop acute fulminant hepatitis. This is even less common with HCV alone, although it becomes more frequent when both HBV and HCV are present together.
Hepatitis B Symptoms & Treatment
- Hepatitis B is a virus found in infected blood, semen and vaginal fluids.
- Its a sexually transmitted infection that can be passed on through unprotected sex. You can also get it from contaminated needles and syringes. Its also commonly passed on from a mother to her baby during birth.
- There is a vaccine to prevent hepatitis B, which is routinely offered to infants as well as at-risk groups.
- You can prevent hepatitis B by practising safer sex, never sharing needles and syringes, and avoiding unlicensed tattoo parlours and acupuncturists.
- Most people dont need treatment for acute hepatitis B. If the infection becomes chronic, there is no cure, but it can be managed with treatment.

What Are Treatment Options For Hepatitis A
Hepatitis A has no particular treatment however, infected people are treated based on their symptoms. The body will get rid of the virus eventually, although it may take a few months for complete recovery.
A person must maintain a proper diet, drink plenty of fluids, and get plenty of rest to recover. Their surroundings should be well ventilated, and the patient should wear loose clothing and avoid hot showers to reduce the intensity of itching if any. The doctor may prescribe antihistamine drugs to control itching.
The doctor will advise you to avoid alcohol, certain medications, such as acetaminophen, and vitamins that require the liver for metabolism. These may increase liver inflammation and damage. It is highly recommended to consult the doctor before taking any over-the-counter medications.
Hospital admission may be required in patients with severe diseases, such as those with acute liver failure or symptoms, such as severe pain, excessive vomiting, confusion, tremors, severe dehydration, and jaundice.
Treatment For Chronic Hepatitis B
If blood tests show that you still have hepatitis B after 6 months, your doctor may recommend medication to reduce the risk of complications of hepatitis B and regular tests to assess the health of your liver.
Treatment is usually offered if:
- your immune system is unable to control the hepatitis B by itself
- there’s evidence of ongoing liver damage
Hepatitis B medications can help keep the virus under control and stop it damaging your liver, although they will not necessarily cure the infection and some people need lifelong treatment.
The main medicines for chronic hepatitis B include peginterferon alfa 2-a and antiviral medicines.

Can Hepatitis C Be Prevented Or Avoided
The only way to prevent hepatitis C is to avoid coming in contact with an infected persons blood. Always have protected sex . Dont do intravenous drugs. Dont share personal care items with a person who has hepatitis C. If youre a health care worker, follow your workplaces standard safety practices.
How Do I Get Hepatitis B Treatment
Usually for adults, hepatitis B goes away on its own and you wont need treatment. Your doctor might tell you to rest, eat well, and get plenty of fluids. You may also get medicines to help with any symptoms you might have but be sure to talk with your doctor or nurse before taking anything.
If you have chronic hepatitis, there are medicines you can take to treat it. Your doctor will tell you about your options and help you get whatever treatment you need.

How Is Hepatitis A Diagnosed
A diagnosis for hepatitis A is done by a doctor based on the symptoms and blood work. However, it is not easy to clinically distinguish hepatitis A from other acute viral hepatitis.
Jaundice may be developed in more than 70 percent of hepatitis A virus-infected children and adults. Physical examination may show enlarged liver and spleen .
A specialized blood test is done to identify the presence of immunoglobulin M antibodies that the body develops against the hepatitis A virus.
An additional test, reverse transcriptase-polymerase chain reaction, is done to detect hepatitis A virus RNA in the body.
Could I Give Hepatitis C To Someone Else
Yes, once you have hepatitis C, you can always give it to someone else. If you have hepatitis C, you cannot donate blood. You should avoid sharing personal items like razors and toothbrushes. It is very rare to pass hepatitis C in these ways, but it can happen. Always use a condom when you have sex. If you have hepatitis C, your sexual partners should be tested to see if they also have it.
Talk to your doctor first if you want to have children. The virus isnt spread easily from a mother to her unborn baby. But it is possible, so you need to take precautions. However, if youre trying to have a baby, do not have sex during your menstrual cycle. The hepatitis C virus spreads more easily in menstrual blood.

Hepatitis B During Pregnancy
If a woman with HBV becomes pregnant, they may transmit the virus to their baby. Women should inform the doctor who delivers their baby that they have HBV.
The infant should receive an HBV vaccine and HBIG with 1224 hours of birth. This significantly reduces the risk that they will develop HBV.
The HBV vaccine is safe to receive while pregnant.
People with a high risk of HBV include:
- the infants of mothers with HBV
- the sexual partners of people with HBV
- people who engage in sexual intercourse without contraception and those who have multiple sexual partners
- men who have sex with men
- people who inject illicit drugs
- those who share a household with a person who has a chronic HBV infection
- healthcare and public safety workers who are at risk of occupational exposure to blood or contaminated bodily fluids
- people receiving hemodialysis, which is a type of kidney treatment
- people taking medications that suppress the immune system, such as chemotherapy for cancer
- those who come from a region with a high incidence of HBV
- all women during pregnancy
People can prevent HBV infection by:
- wearing appropriate protective equipment when working in healthcare settings or dealing with medical emergencies
- not sharing needles
- following safe sexual practices
- cleaning any blood spills or dried blood with gloved hands using a 1:10 dilution of one part household bleach to 10 parts water
A vaccine against HBV has been available since 1982.
People who should receive this vaccine include:
Treatment For Acute Hepatitis B
If you’re diagnosed with hepatitis B, your GP will usually refer you to a specialist, such as a hepatologist .
Many people do not have any troublesome symptoms, but if you do feel unwell, it can help to:
- get plenty of rest
- take over-the-counter painkillers, such as paracetamol or ibuprofen, for tummy pain
- maintain a cool, well-ventilated environment, wear loose clothing, and avoid hot baths or showers if itching is a problem
- take medication, such as metoclopramide, to stop you feeling sick, and chlorphenamine to reduce itching your doctor can give you a prescription for these if necessary
Most people recover completely in a couple of months, but you’ll be advised to have regular blood tests to check that you’re free of the virus and have not developed chronic hepatitis B.

How Will I Know If My Treatment Works
The goal of treatment is to reduce the amount of the hepatitis C virus in your blood to levels that cant be detected after 24 weeks of therapy. The amount of the virus in your blood is called your viral load. At the end of your treatment, your doctor will need to measure your viral load and find out how healthy your liver is. He or she may repeat many of the same tests that were done when you were first diagnosed with hepatitis C.
If your blood has so few copies of the virus that tests cant measure them, the virus is said to be undetectable. If it stays undetectable for at least 6 months after your treatment is finished, you have what is called a sustained virologic response . People who have an SVR have a good chance of avoiding serious liver problems in the future.
Treatment may not reduce your viral load. You may not have an SVR after treatment. If thats true, your doctor will discuss other treatment options with you. For example, if 1 round of treatment did not decrease your viral load enough, your doctor may recommend a second round. Even if treatment doesnt keep you from having active liver disease, lowering your viral load and controlling chronic liver inflammation may help you feel better for a longer time.
Acute Vs Chronic Hepatitis B
A hepatitis B infection can result in either an acute infection or a chronic infection. When a person is first infected with the hepatitis B virus, it is called an “acute infection” . Most healthy adults that are infected do not have any symptoms and are able to get rid of the virus without any problems. Some adults are unable to get rid of the virus after six months and they are diagnosed as having a “chronic infection.” A simple blood test can diagnose an acute or chronic hepatitis B infection.
The risk of developing a chronic hepatitis B infection is directly related to the age at which a person is first exposed to the hepatitis B virus. The younger a person is when they are first infected, the greater the risk of developing a chronic hepatitis B infection:
- More than 90% of infants that are infected will develop a chronic hepatitis B infection
- Up to 50% of young children between 1 and 5 years who are infected will develop a chronic hepatitis B infection
- 5-10% of healthy adults 19 years and older who are infected will develop a chronic hepatitis B infection
The recommendation for hepatitis B vaccination of babies and children is so important because they are at the greatest risk of developing a chronic infection if they are not protected against the hepatitis B virus as soon as possible.

Living With Hepatitis B
If you have hepatitis, you should:
- avoid having unprotected sex, including anal and oral sex, unless you’re sure your partner has been vaccinated against hepatitis B
- avoid sharing needles used to inject drugs with other people
- take precautions to avoid the spread of infection, such as not sharing toothbrushes or razors with other people
- eat a generally healthy, balanced diet there’s no special diet for people with hepatitis B
- avoid drinking alcohol this can increase your risk of developing serious liver problems
- speak to your doctor if you’re thinking of having a baby
People with hepatitis B can usually have a healthy pregnancy, but it’s a good idea to discuss your plans with a doctor first as you may need extra care and your medications may need to be changed.
There’s a risk of pregnant women with hepatitis B passing the infection on to their child around the time of the birth, but this risk can be reduced by ensuring the baby is vaccinated shortly after they’re born.

Is Svr Considered A Cure
The oral DAA treatments are capable of causing a sustained virologic response , which means that the hepatitis C virus is not detected in the blood 12 weeks or more after completing treatment. Your doctor will monitor your virologic response with blood tests. Most people are considered cured when the virus is no longer present after 12 weeks.
Two or more oral antiviral drugs are typically used together to help prevent resistance in patients treated for HCV. Sometimes these treatments still need to be used with older medications such as ribavirin if you have advanced liver disease. Your chances for a cure may be better if you do not have advanced liver disease and have never received HCV treatment before.
Once you reach an SVR, it is highly unlikely for the hepatitis C virus to be detected again unless you are reinfected. Studies have shown this type of relapse occurs in less than 1% of patients who complete treatment. Also, when the virus is cleared from your blood you can no longer transmit the virus to others. However, you should still take precautions to help prevent catching and spreading HCV.
Any liver damage you have won’t be reverse after you reach SVR, but further damage may be minimized with treatment.
