Prevention of Acute Hepatitis C











High-risk behavior such as sharing needles to inject drugs should be avoided.



In the United States all blood donors are tested for hepatitis C to prevent the spread of hepatitis C virus through transfusions. Also even though the chance of getting hepatitis from transfusions is remote doctors use transfusions only when there is no alternative. These measures have dramatically decreased the risk of getting hepatitis from a blood transfusion.



No vaccine for hepatitis C is currently available.


Treatment of Acute Hepatitis C













Antiviral drugs






People with acute hepatitis C are treated with the same drugs used to treat chronic hepatitis C as soon as acute hepatitis C is diagnosed. These drugs may decrease the risk of acute hepatitis C becoming chronic.



People with hepatitis C should not drink alcohol because it can damage the liver further. There is no need to avoid certain foods or to limit activity. People should not take drugs that can damage the liver such as acetaminophen.



Most people can safely return to work after jaundice resolves.


Symptoms of Acute Hepatitis C











At first acute hepatitis C is usually mild and often causes no symptoms. Most people with acute hepatitis C are unaware that they are infected.



Some people with acute hepatitis C have typical symptoms of viral hepatitis. These symptoms include





Loss of appetite




A general feeling of illness (malaise)




Fever




Nausea and vomiting




Jaundice (yellowing of the skin and whites of the eyes)






Acute hepatitis C very rarely becomes severe (fulminant).



Hepatitis C becomes chronic in about 75% of people. Chronic infection is usually mild. However over time about 20 to 30% of people with chronic hepatitis C develop cirrhosis. Liver cancer may develop but usually only after cirrhosis has developed.

Diagnosis of Acute Hepatitis C













Blood tests






Doctors suspect acute hepatitis C when





People have symptoms of acute hepatitis.




Blood tests (liver tests) detect inflammation of the liver (hepatitis).




People have risk factors for getting hepatitis C.






Testing usually begins with blood tests to determine how well the liver is functioning and whether it is damaged (liver tests). Liver tests involve measuring the levels of liver enzymes and other substances produced by the liver.



If tests detect liver abnormalities other blood tests are done to check for hepatitis virus infection. These blood tests can identify parts of specific viruses (antigens) specific antibodies produced by the body to fight the virus and sometimes genetic material (RNA or DNA) of the virus.



Blood tests are done to look for other causes of hepatitis.





The presence of antibodies to hepatitis C suggests that people have been infected with hepatitis C at some time in their life but are not necessarily still infected. If antibodies to hepatitis C are found the hepatitis C RNA test is done to determine whether the infection is current or occurred in the past. Having antibodies to hepatitis C does not protect people from getting hepatitis C. (In contrast having antibodies to hepatitis A and hepatitis B does protect against future infection with these viruses.)


simple explanation



Acute hepatitis C is inflammation of the liver that is caused by the hepatitis C virus and that lasts from a few weeks up to 6 months.


Hepatitis C is spread through contact with blood or other bodily fluids of infected people as occurs when people share unsterilized needles to inject illicit drugs.


Acute hepatitis C often causes no symptoms


Doctors diagnose acute hepatitis C based on blood tests.


No vaccine is available.


Often no specific treatment is recommended for acute hepatitis C.


(See also Overview of Hepatitis Overview of Acute Viral Hepatitis and Hepatitis C Chronic.)


In the United States over 3 600 cases of acute hepatitis C were reported in 2018. However because many cases are not recognized or not reported the actual number of new infections was estimated to be over 50 000 in 2018.


For unknown reasons about one of five people with alcoholic liver disease has hepatitis C. In these people alcohol and hepatitis C work together to worsen inflammation and scarring of the liver (cirrhosis).


Hepatitis C is usually spread through contact with blood of an infected person. Hepatitis C is most commonly transmitted among people who share unsterilized needles to inject illicit drugs. The infection can also be transmitted through unsterilized needles used for tattoos and body piercings.


Transmission through blood transfusions or organ transplants is possible but is now rare. Such transmission was common in the United States until 1992 when widespread screening of the blood supply for the hepatitis C virus began.


Transmission through sexual contact is uncommon as is transmission from an infected pregnant woman to her baby.


Why someone gets hepatitis C sometimes cannot be determined.


At first acute hepatitis C is usually mild and often causes no symptoms. Most people with acute hepatitis C are unaware that they are infected.


Some people with acute hepatitis C have typical symptoms of viral hepatitis. These symptoms include


Loss of appetite


A general feeling of illness (malaise)
