Early Symptoms Of Hepatitis B

Transmission Of Hepatitis B

What are the early signs and symptoms of Hepatitis B & C? | Apollo Hospitals

HBV is often transmitted parenterally, typically via contaminated blood or blood products. Routine screening of donor blood for hepatitis B surface antigen has nearly eliminated the previously common posttransfusion transmission, but transmission through needles shared by drug users remains common. Risk of HBV is increased for patients on dialysis and in oncology units, and for hospital personnel in contact with blood.

Infants born to infected mothers have a 70 to 90% risk of acquiring hepatitis B during delivery Infection Neonatal hepatitis B virus infection is usually acquired during delivery. It is usually asymptomatic but can cause chronic subclinical disease in later childhood or adulthood. Symptomatic infection read more ) unless they are treated with hepatitis B immune globulin and are vaccinated Prevention Neonatal hepatitis B virus infection is usually acquired during delivery. It is usually asymptomatic but can cause chronic subclinical disease in later childhood or adulthood. Symptomatic infection read more immediately after delivery. Earlier transplacental transmission can occur but is rare. The risk of vertical transmission of HBV is also mitigated by treating actively infected pregnant women with high viral loads in their third trimester with tenofovir.

The virus may be spread through mucosal contact with other body fluids , but infectivity is far lower than that of hepatitis A virus, and the means of transmission is often unknown.

What Are The Symptoms Of Hepatitis B And C

In most patients, hepatitis B develops slowly over the course of several decades, and thus most patients have no symptoms. People who have advanced liver disease such as cirrhosis of the liver may experience complications and symptoms that reflect liver failure. Other symptoms include:

  • A buildup of fluid within the abdominal cavity
  • Confusion and tremors , which are complications due to the inability of the liver to filter out toxins that are normally cleaned out by a healthy liver
  • Vomiting of blood, or blood within the stool . This is a complication in which enlarged veins within the esophagus or stomach bleed as a consequence of increased pressure around the diseased liver.

Most patients with chronic hepatitis C infection report no symptoms. But some patients may have very nonspecific symptoms related to fatigue and discomfort on the right side of the abdomen. Often, symptoms that lead to a diagnosis of hepatitis C are noticeable only at the end stage of liver disease, when the patient has developed liver cirrhosis and liver failure.

Because hepatitis B and C typically have no specific symptoms, many people who have the viruses dont even know it.

How Is Hepatitis B Spread

  • Having unprotected sex.
  • Sharing or using dirty needles for drug use, tattoos or piercing.
  • Sharing everyday items that may contain body fluids, including razors, toothbrushes, jewelry for piercings and nail clippers.
  • Being treated medically by someone who does not use sterile instruments.
  • Being bitten by someone with the infection.
  • Being born to a pregnant woman with the infection.

Hepatitis B is not spread by:

  • Kissing on the cheek or lips.
  • Coughing or sneezing.
  • Hugging, shaking hands or holding hands.
  • Eating food that someone with the infection has prepared.

When Will Symptoms Appear After You Have Been Exposed To Hav

It generally takes about 4 weeks for symptoms to appear, but they can start at 2 weeks or they can start up to 8 weeks after you have been exposed. You probably wont get every symptom immediately, but they tend to emerge over days.

Also, you can have no symptoms and have the virus and be contagious. Children especially may be free of symptoms despite being infected.

Hepatitis A: What Happens

Pin on Paramedici

Hepatitis A is highly contagious and can spread from person to person in many different settings. It typically causes only a mild illness, and many people who are infected may never realize they’re sick at all. The virus almost always goes away on its own and does not cause long-term liver damage.

Reduce Your Chance Of Infection

You can reduce your chance of hepatitis B infection by

  • not sharing drug needles or other drug materials
  • wearing gloves if you have to touch another persons blood or open sores
  • making sure your tattoo artist or body piercer uses sterile tools
  • not sharing personal items, such as toothbrushes, razors, or nail clippers
  • using a latex or polyurethane condom during sex

Prevent Infection After Contact With The Virus

If you think you have been in contact with the hepatitis B virus, see your doctor right away. Doctors typically recommend a dose of the hepatitis B vaccine to prevent infection. In some cases, doctors may also recommend a medicine called hepatitis B immune globulin to help prevent infection. You must get the vaccine dose and, if needed, HBIG shortly after coming into contact with the virus, preferably within 24 hours.

How Are Hepatitis B And C Treated

Hepatitis B: Not all patients with chronic hepatitis B infection require treatment. At Yale Medicine, specialists decide on an individual basis whether a patient is an appropriate candidate for treatment. Generally, patients require treatment when their hepatitis B virus level is high, and when laboratory tests demonstrate significant inflammation or injury to the liver.

There are currently seven approved drugs for hepatitis B, two of which are considered to be first-line treatments. These drugs are oral pills taken once daily, and while they’re very effective at suppressing the virus to very low or undetectable levels over the long term, they are not considered curative.

Therefore, the goal of treatment is to control the virus long-term and decrease the risk of hepatitis B related complications such as cirrhosis and liver cancer.

Hepatitis C: For the greater part of the last 20 years, treatment of hepatitis C required the use of a chemotherapy-like injection drug called interferon, which has been associated with serious side effects and a low cure rate. Fortunately, advances in hepatitis C treatments within the last three years now allow for the use of oral medications that are significant improvements in terms of safety and effectiveness.

What Is Involved In A Liver Transplant

Hepatitis A, Hepatitis B, Hepatitis C, Hepatitis D, Hepatitis E – Features, Symptoms, and Treatment

A liver transplant is considered necessary when the liver is damaged and cannot function or in some cases of liver cancer. Your liver is very important. It is responsible for many functions related to making sure that your body stays healthy and is able to digest foods.

You may be eligible for a transplant if you have chronic hepatitis B infection or some of the diseases that may result from it, including liver cancer and cirrhosis. You will have to complete testing and be evaluated before being approved for a transplant. It is likely that you will be placed on a waiting list while an appropriate organ is found.

Donated livers come from two types of donors: living and deceased. Because the liver can regenerate, it is possible to use part of a liver for transplant. The remaining sections in both the donor and the receiver will grow into livers of adequate size.

People who get liver transplants must take anti-rejection drugs for the rest of their lives. These drugs make you more susceptible to infection. However, liver transplants have become more successful over time and continue to improve.

Hepatitis A And B Vaccines

There are vaccines to protect against hepatitis A and B. The CDC recommends hepatitis A vaccination for all children ages 12 to 23 months and for adults who plan to travel or work in areas with hepatitis A outbreaks or who have other risk factors. People with chronic hepatitis B or C should also get the hepatitis A vaccine if they don’t already have immunity to the disease. The hepatitis B vaccine is recommended for all infants at birth and for adults who have any of the risk factors we discussed earlier. There is no vaccine for hepatitis C.

Who Should Be Tested For Hepatitis

Testing is important for anyone with the risk factors we’ve mentioned, particularly injected drug users and people who have had multiple sex partners. Health advocates are also urging people of Asian heritage to get tested. Stanford University’s Asian Liver Center estimates that 1 in 10 Asians living in the U.S. has chronic hepatitis B. Many of them have probably had the virus since birth.

Also, the U.S. Preventive Services Task Force recommends that health care providers offer a one-time hepatitis C screening for anyone born between 1945 and 1965.

Origin Of Antiviral Resistance

The genetic makeup of viruses is constantly changing, which can cause a virus to become resistant to currently available treatments. Viruses can become resistant through spontaneous or intermittent mechanisms throughout the course of an antiviral treatment. Immunocompromised patients, more often than immunocompetent patients, hospitalized with are at the highest risk of developing oseltamivir resistance during treatment. Subsequent to exposure to someone else with the flu, those who received oseltamivir for âpost-exposure prophylaxisâ are also at higher risk of resistance.

Multiple strains of one virus can be present in the body at one time, and some of these strains may contain mutations that cause antiviral resistance. This effect, called the , results in immense variation in any given sample of virus, and gives the opportunity for natural selection to favor viral strains with the highest fitness every time the virus is spread to a new host. Also, recombination, the joining of two different viral variants, and , the swapping of viral gene segments among viruses in the same cell, play a role in resistance, especially in influenza.

Antiviral resistance has been reported in antivirals for herpes, HIV, hepatitis B and C, and influenza, but antiviral resistance is a possibility for all viruses. Mechanisms of antiviral resistance vary between virus types.

HEPATITIS B SOLUTION ~ NATURAL HEALTH

Hepatitis B is endemic in China and other parts of Asia. Most people in the region become infected with HBV during childhood.

In these regions, 8% to 10% of the adult population are chronically infected. Liver cancer caused by HBV is among the first three causes of death from cancer in men, and a major cause of cancer in women. High rates of chronic infections are also found in the Amazon and the southern parts of eastern and central Europe. In the Middle East and Indian sub-continent, an estimated 2% to 5% of the general population is chronically infected. Less than 1% of the population in western Europe and North American is chronically infected.

Hepatitis A: How Does It Spread

It usually spreads through food or water. Food can be tainted when its touched by a person with hepatitis who did not wash their hands after using the bathroom. This transfers tiny amounts of infected stool to the food. Raw shellfish, fruits, vegetables, and undercooked foods are common culprits in hepatitis A outbreaks. The virus can also spread in daycare centers if employees arent careful about washing hands after changing diapers.

How Do Doctors Treat Hepatitis B

Doctors typically dont treat hepatitis B unless it becomes chronic. Doctors may treat chronic hepatitis B with antiviral medicines that attack the virus.

Not everyone with chronic hepatitis B needs treatment. If blood tests show that hepatitis B could be damaging a persons liver, a doctor may prescribe antiviral medicines to lower the chances of liver damage and complications.

Medicines that you take by mouth include

A medicine that doctors can give as a shot is peginterferon alfa-2a .

The length of treatment varies. Hepatitis B medicines may cause side effects. Talk with your doctor about the side effects of treatment. Tell your doctor before taking any other prescription or over-the-counter medicines.

For safety reasons, you also should talk with your doctor before using dietary supplements, such as vitamins, or any complementary or alternative medicines or medical practices.

Deterrence And Patient Education

Patient education remains one of the most important components in preventative measures regarding HBV infection.

Education should be provided to expecting parents about the importance of vaccination and to clarify erroneous beliefs about vaccinations.Patient education should also include counseling about the avoidance of risky behaviors that predispose an individual to be infected, including promiscuous sexual activity or intravenous drug abuse. They should also be advised not to share items such as shaving razors, toothbrushes, or hair combs due to possible transmission via mucosal contact or through microtrauma to protective barriers.

Hepatitis B And Pregnancy

If youâre pregnant, you might pass the virus to your baby at birth. Itâs less likely to happen during your pregnancy.

If your baby gets the virus and isnât treated, they could have long-term liver problems. All newborns with infected mothers should get hepatitis B immune globulin and the vaccine for hepatitis at birth and during their first year of life.

Treatment Options For Hepatitis B

Acute hepatitis B usually doesnt require treatment. Most people will overcome an acute infection on their own. However, rest and hydration will help you recover.

Antiviral medications are used to treat chronic hepatitis B. These help you fight the virus. They may also reduce the risk of future liver complications.

You may need a liver transplant if hepatitis B has severely damaged your liver. A liver transplant means a surgeon will remove your liver and replace it with a donor liver. Most donor livers come from deceased donors.

Blood Tests For Hepatitis B

If you test positive for the hepatitis B surface antigen , you have HBV in your blood. You have a chronic infection if you test positive for HBsAg consistently for at least 6 months.

If you test negative for HBsAg but positive for the hepatitis B surface antibody , you are protected from HBV because youve received the vaccine or recovered from an acute infection.

Another test to detect acute hepatitis B looks for the IgG antibody to hepatitis B core antigen .

Testing positive for the antibody to this antigen the hepatitis B core antibody means either that youre currently infected with HBV, or that you were in the past, depending on the results of the HBsAg and anti-HBs tests.

The hepatitis B e antigen can only be found in the blood during an active infection and signifies high levels of the virus .

On the other hand, having the hepatitis B e antibody means that you have chronic hepatitis B but low levels of the virus, and thus a lower risk of complications.

Unlike these antigen and antibody tests, the hepatitis B viral DNA test can directly detect the presence of the viruss DNA in your blood.

Remember that only your doctor can interpret the results of your tests.
