How Can Hepatitis Be Transmitted

Can Hepatitis B Be Prevented

How Is Hepatitis Transmitted?

The hepatitis B vaccine is one of the best ways to control the disease. It is safe, effective and widely available. More than one billion doses of the vaccine have been administered globally since 1982. The World Health Organization says the vaccine is 98-100% effective in guarding against the virus. Newborns should be vaccinated.

The disease has also been more widely prevented thanks to:

  • Widespread global adoption of safe blood-handling practices. WHO says 97% of the blood donated around the world is now screened for HBV and other diseases.
  • Safer blood injection practices, using clean needles.
  • Safe-sex practices.

You can help prevent hepatitis B infections by:

  • Practicing safe sex .
  • Never sharing personal care items like toothbrushes or razors.
  • Getting tattoos or piercings only at shops that employ safe hygiene practices.
  • Not sharing needles to use drugs.
  • Asking your healthcare provider for blood tests to determine if you have HBV or if you are immune.

General Tips For Prevention

Refrain from engaging in IV drug use and be cautious with all procedures that involve needles.

For example, you shouldnt share needles used for tattooing, piercing, or acupuncture. The equipment should always be carefully sterilized for safety. If youre undergoing any of these procedures in another country, always make sure the equipment is sterilized.

Sterile equipment should also be used in a medical or dental setting.

Poor Infection Control For Tattooing And Piercing

The notes that HCV may be transmitted by receiving tattoos or piercings from unregulated settings with poor infection control standards.

Commercially licensed tattooing and piercing businesses are generally thought to be safe.

More informal settings may not have adequate safeguards to help avoid the spread of infections. Receiving a tattoo or piercing in settings such as in a prison or in a home with friends carries a of HCV transmission

What Does The Government Do To Protect Me

In Canada, several government organizations work together every day to keep your food safe:

  • Health Canada makes food safety standards and policies to help minimize the risk of foodborne illnesses.
  • The Canadian Food Inspection Agency enforces these policies and standards and carries out inspections to make sure the food industry meets its food safety responsibilities. The CFIA works with Health Canada to make sure that foodborne illness is detected early and warnings go out to the public quickly.
  • The Public Health Agency of Canada studies the incidence and causes of diseases in Canada, conducts outbreak surveillance, and coordinates outbreak response.

The Government of Canada works very hard to protect your health and safety:

  • We are carrying out a five-year Food and Consumer Safety Action Plan, to strengthen and modernize Canada’s safety system and make sure you can have confidence in the quality and safety of the food, health and consumer products you buy.
  • We are investing $75 million more in Canada’s food safety system to hire more inspectors, update lab technology, and improve communication with Canadians.
  • We support and participate in public awareness campaigns about safe food practices, like the Canadian Partnership for Consumer Food Safety Education’s Be Food Safe program, which encourages Canadian consumers to think of food safety at every step of the food handling process, from shopping for groceries to re-heating leftovers.

What Is Hepatitis B

Four curable sexually transmitted infections

Hepatitis B is part of a group of hepatitis viruses that attack the liver. It can be passed on via unprotected sex , through contaminated needles and from a pregnant woman to her baby during birth.

You may be more at risk of getting hepatitis B if you inject drugs, are a sex worker, are a man who has sex with men, change partners frequently, are in close contact with someone who has chronic hepatitis B, or your occupation exposes you to the virus, for example, a nurse.

Vaccines for hepatitis B are routinely offered to infants. Adults at a higher risk of getting hepatitis B may also be offered the vaccine.

Hepatitis B does not always cause symptoms and can pass in a few months without treatment . People can also have a lifelong infection , and without appropriate treatment and care, it can become more serious and lead to liver damage or death.

How Hbv Is Spread

It is possible for the hepatitis B virus to be spread through the bodily fluids of an infected person, which is to say that the virus can be transmitted through the blood, sweat, tears, saliva, semen, vaginal secretions, menstrual blood, and breast milk of an infected person. That said, having hepatitis B does not necessarily mean that you are infectious only some people with HBV are actually contagious.

Opportunities for exposure can include sharing a syringe or getting tattoos or body piercings with infected tools. But it also means that it is possible to be exposed during childbirth as well as sexual contact and intercourse. In fact, nearly two-thirds of acute cases of hepatitis B in the United States are caused by sexual exposure.

Though HBV can be spread through blood, there is generally very little risk of contracting the virus through blood transfusions as most countries began screening for it by 1975.

Who Should Be Vaccinated For Hepatitis B

All newborns should be vaccinated. Also, people who are under 18 who were not vaccinated at birth should also get the vaccine. Other groups who should be sure to be vaccinated are those in certain high-risk categories, such as:

  • People who have more than one sexual partner.
  • Men who have sex with men.
  • Adults with diabetes.
  • Sexual partners of infected people and people who share households with infected individuals.
  • People who are exposed to blood and other bodily fluids, including healthcare and public safety professionals, and people who work in jails and other places taking care of people who cant take care of themselves.

Acute Hepatitis B Infection

There is no specific treatment for acute hepatitis B, and most people recover within one to two months. Usually, you can manage symptoms at home with painkillers if necessary. Your healthcare professional should advise you to have regular blood tests and physical check-ups. Most people make a full recovery from acute hepatitis B.

Who Should Get The Hep A And Hep B Vaccines

Can Hepatitis Be Transmitted By Mosquitoes?

Hepatitis A vaccine is made of killed hepatitis A viruses and causes the body’s immune system to produce antibodies against the hepatitis A virus. In the United States, hepatitis A vaccination is recommended for all children at 1 year of age and for individuals in high-risk settings.

Most individuals who receive hepatits B vaccine develop protective antibodies when they get the vaccine. In the United States, hepatitis B vaccination is recommended for all infants at birth, older children and adolescents who did not receive it at birth, and adults in high-risk situations.

A combination vaccine called hepatitis-b-hepatitis-a-vaccine injection protects against both hepatitis A and hepatitis B.

HAV viruses can live outside the human body for months in the environment.

If you have advanced hepatitis B, you might also become a candidate for a liver transplant. This path does not always result in a cure because the virus continues in your bloodstream after a transplant. To prevent being infected again after your transplant, you may be prescribed hepatitis B immunoglobulin with an antiviral agent.

What Occupations Have Increased Risk Of Hepatitis B

In general, occupational groups with increased risk include:

  • Health-care workers repeatedly exposed to blood or blood products or those who are at risk of needlestick injury.
  • Pathologists, laboratory personnel, or embalmers.
  • Dentists, dental assistants, and dental hygienists.
  • Certain staff members of institutions for the developmentally handicapped.
  • Staff of institutions where workers may be exposed to aggressive, biting residents.

Travellers to regions with intermediate or high rates of endemic HBV infection may also consider being vaccinated.

What Is Hepatitis A

Hepatitis A accounts for 20 percent to 25 percent of hepatitis cases in developed countries. Hepatitis A is usually transmitted through the fecal-oral route, meaning a person somehow ingests contaminated feces from an infected person. If an infected person did not wash his or her hands properly after using the bathroom, the disease may spread from the persons hands. The incubation period is two to six weeks, during which the infected individual is contagious.

Another cause of hepatitis A is eating shellfish harvested from contaminated water. Developing countries experience hepatitis A epidemics caused by drinking water contaminated with raw sewage.

The prognosis for hepatitis A patients is excellent with self-limiting course, and recovery is complete. About 85 percent of people with hepatitis A recover within three months, and almost all recover within six months. The disease does not become chronic, and there are no long-term health implications.

Groups At High Risk Of Hep B Transmission

Hepatitis E: Causes, symptoms, and treatment

Hep B can only be passed on through blood-to-blood contact, unprotected sex or during birth so you might be at risk of having hep B if you:

  • have moved to Australia from a country where hep C is widespread

Hepatitis A: Who Is At Risk

A prime risk factor for hepatitis A is traveling to or living in a country with high infection rates. You can check the CDC’s travel advisories to learn about recent outbreaks. Eating raw foods or drinking tap water can raise your risk while traveling. Children who attend daycare centers also have a higher risk of getting hepatitis A.

What Are The Risk Factors For Getting Hepatitis B

Due to the way that hepatitis B spreads, people most at risk for getting infected include:

  • Children whose mothers have been infected with hepatitis B.
  • Children who have been adopted from countries with high rates of hepatitis B infection.
  • People who have unprotected sex and/or have been diagnosed with a sexually transmitted infection.
  • People who live with or work in an institutional setting, such as prisons or group homes.
  • Healthcare providers and first responders.
  • People who share needles or syringes.
  • People who live in close quarters with a person with chronic hepatitis B infection.
  • People who are on dialysis.

How Can You Prevent Hepatitis B And Hepatitis C

What is Hepatitis C? | How is Hepatitis C Transmitted?

Hepatitis B: Vaccination is the best way to prevent all of the ways that hepatitis B is transmitted. People with HIV who do not have active HBV infection should be vaccinated against it. In addition to the 3-dose series of hepatitis B vaccine given over 6 months, as of 2017, there is a 2-dose series given over 1 month.

Hepatitis C: No vaccine exists for HCV and no effective pre- or postexposure prophylaxis is available. The best way to prevent hepatitis C infection is to never inject drugs or to stop injecting drugs by getting into and staying in drug treatment. If you continue injecting drugs, always use new, sterile needles or syringes, and never reuse or share needles or syringes, water, or other drug preparation equipment.

Blood Transfusion/receipt Of Blood Products

Early case-control studies of patients with newly acquired, symptomatic non-A, non-B hepatitis found a significant association between disease acquisition and a history six months prior to illness of blood transfusions, injection drug use, health care employment with frequent exposure to blood, personal contact with others who had hepatitis, multiple sexual partners or low socioeconomic status. Today, HCV is rarely transmitted by blood transfusion or transplantation of organs due to thorough screening of the blood supply for the presence of the virus and inactivation procedures that destroy bloodborne viruses. In the last several years, blood banks have instituted techniques that utilize nucleic acid amplification of the hepatitis C virus, which will detect the presence of virus even in newly-infected patients who are still hepatitis C antibody-negative. These techniques are estimated to have prevented 56 transfusion-associated HCV infections per year in the U.S. since 1999, and have lowered the current risk of acquiring HCV via transfused blood products to 1 in 2 million.

What If You Test Positive

If a test says you have viral hepatitis, you can take steps to protect the ones you love. For hepatitis A, wash hands frequently. For hepatitis B and C, avoid sharing nail clippers, razors, or toothbrushes. Hepatitis B, and sometimes hepatitis C, can be passed through sexual contact. Make sure everyone in your household gets the hepatitis B vaccine. An important step is to see a specialist to discuss treatment options.

How Are Hepatitis B And Hepatitis C Spread From Person To Person

Like HIV, the hepatitis B and hepatitis C viruses spread:

  • From mother to child: Pregnant women can pass these infections to their infants. HIV-HCV coinfection increases the risk of passing on hepatitis C to the baby.
  • Sexually: Both viruses can also be transmitted sexually, but HBV is much more likely than HCV to be transmitted sexually. Sexual transmission of HCV is most likely to happen among gay and bisexual men who are living with HIV.

How Is Hepatitis B Treated

Hepatitis A

Your healthcare provider will treat you based on what type of hepatitis B you have, acute or chronic.

Acute hepatitis B infections

If you develop an acute form of the condition, you probably wont need medical treatment. Instead, your doctor will likely suggest that you get plenty of rest, drink lots of fluids and maintain a healthy diet to support your body as it fights off the infection.

Chronic hepatitis B infections

If you have chronic hepatitis B, you might be a candidate for drug therapy. Usually, drug therapy is used only if you have active liver disease. There are seven drugs that are approved by the U.S. Food and Drug Administration to treat hepatitis B. Two are injectable forms of interferon, while the five other antivirals are tablets.

You will need to take these medications every day. They help by slowing the viruss ability to multiply in your system. This helps reduce swelling and liver damage. Youll need to be regularly monitored for early signs of liver damage and liver cancer. Your healthcare provider will want to see you once or twice a year.

Hepatitis C Symptoms & Treatment

FAST FACTS:

  • Hepatitis C is found in infected blood. It is also rarely found in semen and vaginal fluids.

  • Hepatitis C is mainly passed on through using contaminated needles and syringes or sharing other items with infected blood on them. It can also be passed on through unprotected sex, especially when blood is present.

  • You can prevent hepatitis C by never sharing needles and syringes, practising safer sex, and avoiding unlicensed tattoo parlours and acupuncturists.

  • Hepatitis C will often not have any noticeable symptoms, but a simple blood test carried out by a healthcare professional will show whether you have hepatitis C.

  • In the early stages, some peoples bodies can clear a hepatitis C infection on their own, others may develop chronic hepatitis C and will need to take antiviral treatment to cure the infection.

  • Without treatment, chronic hepatitis C can lead to permanent liver damage.

Hepatitis C is part of a group of hepatitis viruses that attack the liver.

Its mainly passed on through contaminated needles, either from injecting drugs or from needle stick injuries in healthcare settings. It can also be transmitted sexually, especially during anal sex or other types of sex that may involve blood.

Some groups are more at risk of getting hepatitis C than others, including people who use drugs, people in prisons, men who have sex with men, health workers and people living with HIV.

Can You Be A Blood Or Organ Donor

People with hepatitis C cant currently donate blood. The American Red Cross eligibility guidelines prohibit people who have ever tested positive for hepatitis C from donating blood, even if the infection never caused symptoms.

According to the Department of Health and Human Services , information on organ donation, those with underlying medical conditions shouldnt rule themselves out as organ donors. This reflects new guidelines for organ donation announced by the HHS.

People with HCV are now able to be organ donors. This is because advances in testing and medical technology can help the transplant team determine which organs or tissues can be safely used for transplantation.

How To Prevent Transmission

Between 2% and 6% of adults infected with hepatitis B virus will develop chronic hepatitis B. Chronic hepatitis B can lead to liver failure and liver cancer, so protecting yourself is important.

The hepatitis B vaccine is safe for almost everyone and about 95% effective for providing long-term protection against hepatitis B infection.

While anyone can benefit from the vaccine, people who are at a greater risk of being exposed to the virus because of their work, lifestyle or medical history are strongly encouraged to be immunized. In many countries, babies born to infected mothers get vaccinated at birth. All babies born in the United States are routinely vaccinated.

Hepatitis B immune globulin , is another way to prevent hepatitis B infection in babies born to infected mothers or after exposure to the virus. This uses concentrated antibodies to provide immediate protection. According to the Centers for Disease Control and Prevention, it is given as a shot and can provide short-term protection against hepatitis B.

Because the hepatitis B vaccine does not protect against HIV, hepatitis C or other diseases spread through sex and contact with blood, it’s still important to keep using basic protective strategies. Practicing safer sex and not sharing needles are recommended even if you’re immune to hepatitis B.
