Is Hepatitis C A Blood Borne Pathogen

What Are The Causes Of Hepatitis C

Even if youve had HCV before, you can still contract the virus again. It is transmitted by blood-to-blood contact with an individual who has an HCV infection.

Some of the ways that HCV is passed between people include:

• Sharing items like toothbrushes or razors
• Organ transplants
• Sexual contact if blood is exchanged
• Childbirth
• Sharing needles
• Getting a piercing or tattoo with equipment that isnt sterile

Some people are at a higher risk for transmission with HCV than others. These people include those who:

• Were born to a mother who had hepatitis C
• Received a blood transfusion before 1992
• Received hemodialysis treatment for a long period of time
• Had an organ transplant prior to 1992
• Had a sexual partner who had hepatitis C
• Received blood products such as clotting factor concentrates before 1987
• Have used previously-used needles

Hepatitis is transmitted through blood-to-blood contact, but people sometimes mistakenly assume it can also be spread through touch or through the air. You cannot transmit hepatitis C by kissing, hugging, or sharing food. It also cant be transmitted through coughing or through getting bit by a mosquito.

Who Needs A Hepatitis C Test

As there is currently no vaccine for hepatitis C. It leads to the development of other serious illnesses. For these reasons, the CDC has made a number of recommendations regarding screening. Their first recommendation is that all persons born between 1945-1965 take a test for hepatitis C.

Their most recent recommendations are that all adults over 18 should have a test at least once in their lifetime. Also, all pregnant women should take a test during each pregnancy.

All those at risk need regular screening. Additionally, if you have ever been in prison, if you received treatment of hemophilia prior to 1987, or are HIV-positive, you should take a test for hepatitis C.

Prevention: Work Practices & Engineering Controls

Avoiding exposure is the best protection. To do this personal protection devices and practices listed below are to be used or followed.

However, because no system is perfect, anyone who works with human blood or blood products or is at risk of exposure during their job will be offered free vaccinations for Hepatitis B. This vaccination consists of three shots given at 0, 1, and 6 months apart with no boosters in the future.

“Universal Precautions” is the name used to describe a prevention strategy in which all blood and potentially infectious materials are treated as if they are, in fact, infectious, regardless of the perceived status of the source individual. In other words, whether or not you think the blood/body fluid is infected with bloodborne pathogens, you treat it as if it is. This approach is used in all situations where exposure to blood or potentially infectious materials is possible. This also means that certain engineering and work practice controls shall always be utilized in situations where exposure may occur.

Epidemiology Of Blood Contact

To understand the nature, frequency, and prevention of percutaneous injuries and mucocutaneous blood contacts among HCWs, prospective observational studies have been performed in different patient care settings .1). The percentage of procedures with at least one blood contact of any type ranged from 3% of procedures performed by invasive radiology personnel in a study in Dallas, Tex. , to 50% of procedures performed by surgeons in a study in Milwaukee, Wisc. . The percentage of procedures with at least one injury caused by a sharp instrument also varied widely, from 0.1 to 15%. These differences may be related to variations in study methods, procedures observed, and precautions used by the workers performing the procedures.

Bloodborne Pathogens In Hospitals

Bloodborne pathogens are a threat to patients in the hospital. If a patient is not taken well care of with precaution, then they could be affected by this. A pathogen, in general, is something that can cause disease. A bloodborne pathogen, specifically, is an infectious germ that can flow through the human bodys blood, causing disease. This pathogen has multiple ways of getting spread into the blood and is not only a threat to hospital patients, but to people outside those walls as well. There

Detection And Diagnosis Of Hbv Infection

The incubation period for acute hepatitis B ranges from 45 to 160 days, with an average of 120 days. Exposure to HBV can lead to an acute infection which may result in a chronic infection. Acute hepatitis B resembles other forms of viral hepatitis and cannot be distinguished based on history, physical examination, or serum biochemical tests.

The diagnosis of acute HBV infection is confirmed by the demonstration in serum of hepatitis B surface antigen , which appears well before onset of symptoms and before development of antibody to hepatitis B core antigen , and immunoglobulin M antibody to HBc, which appear at approximately the same time as symptoms . The presence of IgM anti-HBc indicates recent HBV infection, usually within the preceding 4 to 6 months. The presence of hepatitis B e antigen in serum correlates with HBV replication, high titers of HBV, and infectivity. Persons who are positive for HBeAg typically have 108 to 109 HBV particles per ml of blood . In persons who resolve acute HBV infection, antibody to HBsAg develops and indicates immunity. The persistence of HBsAg for 6 months after the diagnosis of acute HBV is indicative of progression to chronic HBV infection.

Hepatitis C Signs And Symptoms

Much like with HIV and Hepatitis B, signs and symptoms for Hepatitis C are unreliable and may or may not be present. And why proper testing for all the above is the only sure-fire way to know if an infection is present.

Hepatitis C symptoms include, but are not limited to:

• Yellow skin, known as jaundice
• Yellowing eyes
• Fever

Chronic Hepatitis C Symptoms

There are often no symptoms in the early stages of hepatitis C infection. The symptoms only become apparent when the liver has already been damaged.

The symptoms of liver disease resulting from HCV can include:

• Bleeding and bruising easily
• Itching

Other signs of a hepatitis C infection can include confusion, drowsiness, and slurred speech.

These are the general symptoms of liver disease. Hepatitis C is one of a number of causes of liver disease. A doctor will be able to diagnose whether hepatitis C is causing these symptoms through a blood test.

What Is The Treatment For Hepatitis C

The good news for those infected with HCV is that it is highly curable with antiviral therapy. The purpose of these drugs is to clear the body of the virus by 12 weeks after completing treatment.

Medication regimens vary. The doctor treating you will take into account the hepatitis C genotype, other medical conditions, and extent of liver damage. Direct-acting antiviral tablets are some of the safest and most effective treatments for HCV.

The treatment normally lasts for 8 to 12 weeks. These drugs cure or achieve sustained virological responses in more than 95% of patients, and have limited side effects. Effective treatment of the hepatitis C virus reduces chronic HCV infection-related complications.

Hepatitis C: A Silent Killer

When a doctor uses the term Hepatitis C or HCV, what comes to mind? Many people have little to no knowledge of what it is. Is it deadly? Is there a cure? Is it a virus or disease? There are many questions that enter the mind because there are many concerns associated with an unknown illness. Several people wonder if the virus is similar to hepatitis A or B because there has been education throughout the years that provides more awareness surrounding the two known viruses, but it is discovered there

What Are All The Blood Borne Diseases

Bloodborne pathogens are microorganisms such as viruses or bacteria that are carried in blood and can cause disease in people. There are many different bloodborne pathogens, including malaria, syphilis, and brucellosis, and most notably Hepatitis B , Hepatitis C and the Human Immunodeficiency Virus .

How Is Hepatitis C Transmitted

As HCV is a bloodborne pathogen, it can only be spread when blood contaminated with HCV enters the bloodstream of an uninfected person. As the virus takes many different forms or genotypes, treatment options will vary.

Hepatitis C can be transmitted by:

• Sharing needles/syringes or other equipment when taking drugs
• Giving birth infected mothers can pass it to their baby
• Exposure to contaminated blood in a healthcare setting
• Sex with an infected person
• Unhygienic tattoo or body piercing practices
• Sharing personal items such as razors and toothbrushes
• Blood transfusions and organ transplants, especially prior to 1992

Other contact with infected individuals such as hugging, breastfeeding, and kissing do not spread the HCV virus. It is also not spread by coughing or sneezing. If you are breastfeeding, cracked or bleeding nipples are a danger to your child. Wait until these have healed to continue breastfeeding.

Understanding Bloodborne Pathogens Essay

Understanding Bloodborne PathogensBloodborne Pathogens are pathogenic microorganisms that can eventually cause disease. They are found in human blood and other bodily fluids such as synovial fluid, semen, vaginal secretions, cerebrospinal fluid and any other fluid that mixes or has contact with blood. The bloodborne pathogens are pathogenic, which means they are disease causing, and they are also microorganisms, which means that they are very small so the human eye cannot see them.Bloodborne pathogens

Preventing The Spread Of Hcv

It is very important that those who work in health care settings are aware of the danger of hepatitis C and how to protect themselves. Bloodborne pathogen training gives staff members the tools they need to keep themselves and others safe.

Knowledge is the key to preventing the spread of HCV. If you know that you have the virus, avoid engaging in any of the practices listed above that could spread it to others. If you are a close associate of someone who is infected, take practical steps to limit your risk of exposure.

If you have been successfully treated for hepatitis C, it is still possible to be infected again. If you engage in practices that put you at risk, it is important to be regularly tested, as the infection is often silent without symptoms.

Who Is At Risk For Exposure

People who work in hospitals, clinical labs, housekeeping, first responders and any other work settings where they may come in contact with bodily fluids are at risk of BBPs. Workers who are exposed to bloodborne pathogens can be at risk for serious or life-threatening illnesses like HBV, HCV, and HIV.

Acute Hepatitis C Symptoms

Those who do have symptoms will often experience jaundice, vomiting, fatigue, fever, and aching muscles. In the acute phase, if symptoms appear, they usually last between two weeks and three months.

For those who do not receive treatment and whose bodies do not clear the virus, chronic hepatitis C will develop.

Management Of Exposure To Bloodborne Pathogens

Daniel Gregson, MD, FRCP

Percutaneous exposure to blood isfrequent in health care settings. Fortunately, transmission of bloodborne pathogensoccurs infrequently due to their low prevalence in the general population and the efficacyof hepatitis B immunization. Transmission rates are highest following percutaneousexposure to HBV positive blood , intermediate for HCV and lowest for HIV.

Health care facilities, including dental offices and clinics, are responsible forensuring that percutaneous exposures are minimized through preventative procedures and areappropriately managed when they do occur.1-3

• Management of exposure includes:

• general wound care and cleaning

• counselling of the exposed worker regarding bloodborne pathogens

• documentation of the incident with a review of the cause to determine if such exposures can be prevented in the future

• postexposure assessment and prophylaxis for the health care worker if indicated

• baseline and follow-up serology of the health care worker if indicated.

Unfortunately, no vaccines or prophylactic drug treatments prevent the transmission ofhepatitis C. For those who have had significant exposure, base-line liver enzymes shouldbe recorded and hepatitis C serology should be carried out with repeat testing at 6 weeks,3 months and 6 months. People whose liver enzymes become elevated or have a positiveantibody test should be urgently referred to a specialist with expertise in managinghepatitis C.

Essay Blood Borne Pathogens And Disease Transmission

Pathogens are a type of microorganism that spreads viral and bacterial diseases. These diseases when present in human blood and body fluids are known as blood borne pathogens, and can spread from one person to another. The most serious types of blood borne diseases are the hepatitis B virus and hepatitis C virus , which can cause liver damage and HIV , which is responsible for causing AIDS

Understanding Bloodborne Pathogen Exposure

Bloodborne pathogens can be transmitted in a number of ways:

• Direct contact occurs when infected body fluid or blood from one individual enters another individuals body. An example of this would be someone elses blood splashing into your eye.
• Indirect contact occurs whenan object containing the blood or body fluid of an infected person touches someones skin.
• Respiratory droplet transmission occurs when an infected person sneezes or coughs and the droplets are inhaled by another person.

What Is The Risk Of Exposure

Contact with bloodborne pathogens can result in the contraction of infectious diseases such as human HIV, HBV, HCV, and many others. The following information describes each of the 3 most common BBPs, how they are spread and how to prevent exposure.

HIV

HIV weakens a persons immune system by destroying important cells that fight disease and infection. There is currently no effective cure for HIV. But with proper medical care, HIV can be controlled. Some people in the US are more likely to get HIV than others because of their lifestyles.

Some people have flu-like symptoms within 2 to 4 weeks after infection . These symptoms may last for a few days or several weeks.

Possible symptoms include:

• Mouth ulcers

HBV

Hepatitis B is a liver infection caused by the hepatitis B virus . HBV is spread when blood, semen, or other body fluids from a person infected with the virus enters the body of someone who is not infected. This can happen through sexual contact sharing needles, syringes, or other drug-injection equipment or from mother to baby at birth.

Not all people newly infected with HBV have symptoms, but for those that do, symptoms can include fatigue, poor appetite, stomach pain, nausea, and jaundice. For some people, HBV is a short-term illness. For others, it can become a long-term, chronic infection that can lead to serious, even life-threatening health issues like cirrhosis or liver cancer.

The best way to prevent hepatitis B is to get vaccinated.

What Are Bloodborne Pathogens

Pathogens are viruses, bacteria, or other microorganisms that can lead to disease. Bloodborne pathogens are any infectious microorganisms in human blood that can spread disease through contamination by blood. There are three bloodborne pathogens that are of particular concern to health workers, which are HIV, hepatitis B, and hepatitis C.

A number of blood-borne diseases can also be contracted through other means. This can include intravenous drug use and high-risk sexual behavior.

Clinical or laboratory settings are places where blood poses the greatest threat to health. This is due to injuries that result from needlesticks, which often occur due to improper disposal of needles.

Standard medical practice regards all blood as well as any bodily fluids to be potentially infectious. This is because it can be very difficult to identify which pathogens are contained in any given blood sample and because some of these diseases can be lethal.

You can learn more about some of the most common bloodborne pathogens here.
