National hepatitis surveillance data shows that approximately 400 health care workers became infected with HBV in 2001. The chance of becoming infected with hepatitis B from a sharps injury is estimated to be between six and 30 percent. After adjusting for under-ascertainment and under-reporting, the estimated number of new HBV infections in 2016 was 20,900. In 2016, there were 3,218 cases reported to CDC. According to the CDC, new cases of HBV have not been trending either up or down since 2012, but rather have been fluctuating at around 3,000 new cases per year. Individuals infected with HBV at birth have a much higher likelihood of chronic infection, with approximately 90 percent of infants and 25–50 percent of children aged one to five years remaining chronically infected with HBV after initial infection. Approximately five percent of adult patients develop chronic infection with hepatitis B, which carries an estimated 20 percent lifetime risk of dying from cirrhosis and 6 percent risk of dying from liver cancer. Symptoms include jaundice, fever, nausea, and abdominal pain. Hepatitis B virus can cause serious liver damage and death. ![]() Go to CDC’s HIV Basics for more information. The CDC no longer collects data on occupational HIV pdf icon, so numbers greatly under-estimate the incidence and prevalence of occupational HIV. Other researchers estimate that the number of cases of occupationally acquired infections is much higher. Most of these cases involved nurses and lab technicians. Of the 57 documented cases, 48 were associated with percutaneous injury (puncture/cut injury). health care workers between 1981 and December 2006. The CDC has reported 57 documented cases and 140 possible cases of HIV transmission to U.S. The estimated risk of HIV infection from a sharps injury is about 0.3 percent (1 in 300). This can mean both patient and health care worker are unaware of potential exposure risks. Approximately 1 in 7 do not know they have HIV because they have not been tested. The person is also more vulnerable to pneumonias, intestinal disorders, and fungal infections. Once a person becomes immunocompromised, he or she can exhibit symptoms of weight loss, persistent low-grade fever, night sweats, and flu-like symptoms. Human immunodeficiency virus (HIV) disables the body’s immune system until it is no longer capable of fighting infection. This puts them at risk of exposure to blood and body fluids and vulnerability to bloodborne pathogens. When personal protective equipment is not readily available or accessible, employees are less likely to wear it. ![]()
