Aplc Hepatitis B Quiz

Explanation
The correct answer is 350-400 million. Chronic hepatitis B is a viral infection that affects the liver. It is estimated that a large number of people worldwide are living with chronic hepatitis B, with the number ranging from 350-400 million. This makes it a significant global health issue, with a high prevalence rate.

Explanation
Asian Americans have a higher prevalence of chronic hepatitis B infection compared to non-Asian Americans. The correct answer indicates that 1 out of 10 Asian Americans are chronically infected with hepatitis B, while 1 out of 1000 non-Asian Americans are chronic hepatitis B carriers. This suggests that the rate of chronic hepatitis B infection is significantly higher among Asian Americans compared to non-Asian Americans.

Explanation
During a routine medical check-up, your doctor may examine you for various health conditions, but hepatitis B is not typically included in a routine check-up. Hepatitis B is usually tested for when there is a specific reason to suspect its presence, such as symptoms or risk factors. Therefore, the statement that your doctor examines you for hepatitis B during a routine check-up is false.

Explanation
Hepatitis B can be contracted through three main routes: contaminated blood, an infected mother at birth, and unprotected sexual activity with an infected person. Contaminated blood can occur through sharing needles or other drug paraphernalia, receiving blood transfusions with infected blood, or through accidental needlestick injuries. Transmission from an infected mother to her baby can occur during childbirth. Unprotected sexual activity with an infected person, especially when there are open sores or breaks in the skin, can also lead to transmission of the virus.

Explanation
Yes, the 31-year old competitive athlete could still be a chronic hepatitis B carrier even after receiving the vaccination. The hepatitis B vaccine is highly effective in preventing hepatitis B infection, but it does not guarantee complete protection in all individuals. There is a small possibility that the athlete may have already been infected with hepatitis B before receiving the vaccine, or the vaccine may not have provided full immunity. Additionally, some individuals may not respond adequately to the vaccine and may still become carriers of the virus.

Explanation
Chronic hepatitis B carriers usually do not exhibit any symptoms. This means that they may not experience vomiting, fatigue, nausea, appetite loss, or any other noticeable signs of the infection. However, even in the absence of symptoms, carriers can still transmit the virus to others, which is why it is important for them to undergo regular monitoring and take necessary precautions to prevent the spread of the disease.

Explanation
Chronic hepatitis B infection can lead to liver failure, liver cancer, and cirrhosis. Liver failure occurs when the liver is no longer able to function properly, leading to a range of serious symptoms and complications. Liver cancer, also known as hepatocellular carcinoma, is a potential consequence of long-term hepatitis B infection. Cirrhosis is a condition in which the liver becomes scarred and damaged, impairing its ability to function effectively. All three of these outcomes are potential risks for individuals with chronic hepatitis B infection.

Explanation
Without appropriate treatment or monitoring, a person with chronic hepatitis B is at risk of developing complications such as liver cirrhosis and liver cancer. These complications can be life-threatening and increase the risk of death. Therefore, the correct answer is 1 in 4 (25%), indicating that 25% of individuals with chronic hepatitis B may die from its complications if not properly managed.

Explanation
The correct answer is receiving vaccination, condom use, and avoiding infected needles. Hepatitis B can be prevented by receiving the hepatitis B vaccine, which provides long-term immunity against the virus. Condom use can help prevent the transmission of the virus through sexual contact. Avoiding infected needles is important to prevent the spread of hepatitis B through sharing needles or other drug paraphernalia. Avoiding sanitary cooking methods and contaminated water are not effective methods for preventing hepatitis B.

Explanation
Chronic hepatitis B cannot be completely cured. However, with proper treatment, the virus can be controlled and the progression of liver damage can be slowed down. Treatment options include antiviral medications that help to suppress the virus, reduce liver inflammation, and lower the risk of complications. Regular monitoring and adherence to treatment are essential for managing chronic hepatitis B.

Explanation
Appropriate monitoring and treatment of patients with chronic hepatitis B can reduce the risk of dying from liver cancer or liver failure. This means that if patients with chronic hepatitis B receive proper monitoring and treatment, their chances of developing liver cancer or liver failure decrease, ultimately reducing the risk of death. Therefore, the statement "Yes" is correct.

Explanation
Hepatitis B causes a significant proportion of primary liver cancer cases, specifically 80%. This means that 80% of individuals who develop primary liver cancer can attribute it to the Hepatitis B virus. This highlights the strong association between Hepatitis B infection and the development of liver cancer, emphasizing the importance of prevention and vaccination against Hepatitis B to reduce the risk of liver cancer.
