Hepatitis C Surveillance 2020
What is Hepatitis C
Hepatitis C is a liver disease caused by the hepatitis C virus (HCV). HCV is a bloodborne virus. Transmission can happen through sharing needles, syringes, or other drug-injection equipment; from the gestational parent to baby during pregnancy or at birth; or rarely through sexual contact.
Today, in the United States, the majority of persons become infected with HCV by sharing needles or other equipment used to inject drugs. For certain persons, hepatitis C is a short-term illness, but for more than half of persons who become infected with HCV, it becomes a long-term, chronic infection.
Like chronic hepatitis B, chronic hepatitis C is a serious disease that can result in cirrhosis, liver cancer, and death. Persons might not be aware of their infection because they do not have symptoms.
Since 2013, highly effective, well-tolerated curative treatments have been available for hepatitis C, but no vaccine for preventing hepatitis C is yet available.
The best way to prevent hepatitis C is by avoiding behaviors that can spread the disease, especially injecting drugs with non-sterile injection equipment.

Acute Hepatitis C in 2020
The incidence rate of acute hepatitis C has more than doubled since 2013, and increased 15% from 2019.
In 2020, there was a change to how public health defines a case of acute hepatitis C. This more sensitive and accurate definition helped capture cases that the less sensitive definition might have missed in the past. The increase in 2020 however may still be an underestimate because of decreases in testing that occurred due to the impact of the COVID-19 pandemic.
Also in 2020, CDC published universal adult and pregnancy screening guidelines. It is important that health care professionals, public health officials, and organizations involved in the development, implementation, delivery, and evaluation of clinical and preventive services follow and use these recommendations.
