The hepatitis C virus causes serious liver damage and can be fatal. An infection can occur without or only mild symptoms. Baby boomers (born between 1945 and 1965) have the highest prevalence in the United States, killing more than 60 other infectious diseases during this combined generation. As there is no vaccine for HCV, it is a pathogen of great importance from an occupational risk perspective. National Institute of Heart, Lungs and Blood. What are the risks of a blood transfusion? Available from www.nhlbi.nih.gov/health/health-topics/topics/bt/risks. Updated: January 30, 2012; Accessed June 12, 2017. If personal protective equipment is not readily available or accessible, employees are less likely to wear it. This puts them at risk of being exposed to blood and bodily fluids and being sensitive to blood-borne pathogens.

The number of health care workers infected with HIV as a result of workplace exposure is low when the frequency of exposure to blood and body fluids in clinical and laboratory work is taken into account. Human immunodeficiency virus (HIV), hepatitis B virus (HBV) and hepatitis C virus (HCV) are three of the most common blood-borne pathogens that put health workers at risk. However, blood-borne pathogens are involved in the transmission of more than 20 other pathogens (Beltrami et al 2000External mark). Today, co-infection with several blood-borne diseases and multidrug-resistant organisms, including HIV, hepatitis B or C, methicillin-resistant Staphylococcus aureus (MRSA) and diabetes-related comorbidities, means that occupational exposure of health workers may pose an even higher risk than in previous years. New health care workers performing procedures prone to exposure must demonstrate that they are not infected with HIV and hepatitis C and have a low risk of hepatitis B transmission. These clearance tests must be carried out before confirming an appointment to a body requiring the execution of procedures that may be exposed. Most of these cases involved nurses and laboratory technicians. Other researchers estimate that the number of cases of occupational infections is much higher.

The CDC no longer collects data on the occupational HIVpdf symbol, so the numbers significantly underestimate occupational HIV incidence and prevalence. However, the total number of acute HCV infections that occurred each year ranged from 100,000 in 1991 to 41,200 in 2016; Two to four percent were health care workers exposed to blood in the workplace. Age plays a role in the chronicity of hepatitis B. The younger a person is when infected with the hepatitis B virus, the greater the likelihood of developing a chronic infection. About 9 out of every 10 infected infants develop a chronic infection for life. The risk decreases as the child grows. About one in three children who are infected before the age of 6 develop chronic hepatitis B. In contrast, almost all older children (people aged ≥ 6 years) and adults infected with the hepatitis B virus recover completely and do not develop a chronic infection. The hepatitis B virus can infect infants, children, adolescents and adults. It`s not a genetic disease – it`s a blood-borne infectious disease.

Although any person may be at risk of hepatitis B infection throughout their lifetime, there are groups of people who are at greater risk because of their place of birth, occupation or lifestyle choices. When symptoms appear, they begin on average 90 days (or 3 months) after exposure to the virus, but they can occur at any time between 8 weeks and 5 months after exposure. They usually last for several weeks, but some people may feel sick for up to 6 months. Although anyone can get hepatitis B, these people are more at risk: hepatitis B is NOT transmitted by chance. It cannot be spread through toilet seats, door handles, sneezing, coughing, cuddling or eating with a person infected with hepatitis B. Tuesday JL.

49 (5 suppl):S112-21. [Medline]. There have been cases where infected health workers have transmitted BBVs to patients. In the UK, guidelines are in place to prevent healthcare workers from performing procedures that put patients at risk of infection, and these policies have significantly reduced transmission in this environment. Advice is available for both existing health workers and those who have just attended the NHS. Hepatitis B is spread when blood, semen or other body fluids infected with the hepatitis B virus enter the body of a person who is not infected. People can become infected with the virus from: The overall risks of the three most common blood-borne viruses transmitted from an infected patient to a healthcare worker (HCW) have been estimated, as shown in the table below. Hepatitis B is the most easily transmissible virus and the human immunodeficiency virus (HIV) is the least. Healthcare workers have a higher risk of infection by patients than the other way around. Transmission rates in the UK appear to be higher than in other countries. This is likely due to the more active approach to surveillance and identification of such cases in the UK. The estimated risk of HIV infection, from sharps injuries, is about 0.3% (1 in 300).

The CDC reported 57 documented cases and 140 possible cases of HIV transmission to U.S. health workers between 1981 and December 2006. Of the 57 documented cases, 48 were associated with a percutaneous injury (puncture/cut injury). Transmission of HCV through workplace exposure occurs, with the greatest risk of transmission from patients to health care workers through needlestick injuries and other acute exposures. On July 27, 2020, the American Society of Clinical Oncology (ASCO) released preliminary guidelines recommending that all people with cancer be screened for hepatitis B before starting cancer treatment. According to the ASCO statement, up to 90% of people diagnosed with cancer have at least one risk factor for hepatitis B. Cancer treatments can suppress the immune system and cause the virus to reactivate, which can lead to severe liver damage or liver failure. Statistics on cases of seroconversion and mucocutaneous exposure among healthcare workers in the UK can be found in the Health Protection Agency`s Eye of the Needle report. Most people with chronic hepatitis B have no symptoms, don`t feel sick, and remain symptom-free for decades. If and when symptoms appear, they are similar to the symptoms of an acute infection, but may be a sign of advanced liver disease. About 1 in 4 people who become chronically infected in childhood, and about 15% of those who become chronically infected after childhood, eventually die from serious liver disease such as cirrhosis of the liver (scarring of the liver) or liver cancer.

Some people still have no symptoms even after their liver has become ill, although some blood tests for liver function may show some abnormalities. Groups at high risk of HBV infection include intravenous (IV) drug users, people born in endemic areas, and men who have sex with men. [26, 30] Other vulnerable individuals include health care workers exposed to infected blood or bodily fluids, recipients of multiple blood transfusions, patients undergoing hemodialysis, heterosexual people with multiple partners or with a history of sexually transmitted diseases, institutionalized persons (e.B. Prisoners), and household contacts or sexual partners of HBV carriers. [26, 30] No. If you have been infected with hepatitis B in the past, you cannot re-infect yourself. However, some people, especially those who were infected in early childhood, remain infected for life because they never removed the virus from their bodies. These people are thought to have a chronic infection and are at risk of developing severe liver disease. Yes. The hepatitis B vaccine is safe and pain at the injection site is the most common side effect.

As with any medication, there is a very low risk of a serious problem occurring after vaccination. The safety of vaccines is constantly monitored. For more information, visit the CDC`s vaccine safety website. Koneru A, Nelson N, Hariri S, et al. Increased detection of hepatitis C virus (HCV) in women with reproductive potential and potential risk of vertical transmission – United States and Kentucky, 2011-2014. MMWR Morb Mortal Wkly Rep. 2016 Jul 22. 65 (28):705-10.

[Medline]. Acute hepatitis B is a short-term condition that occurs within the first 6 months after exposure to the hepatitis B virus. Some people with acute hepatitis B do not have or only a mild illness. In others, acute hepatitis B causes a more serious illness that requires hospitalization. The number of reported cases of acute hepatitis B among health care workers has declined in recent years, due to increased risk awareness, the introduction of safer work practices and widespread vaccination. .
