Explanation
d is correct
Hepatitis B spreads through body fluid including sweat. This is why there is a campaign pushing for the screening of athletes involved in contact sports like football and wrestling for hepatitis B.
a is incorrect
Hepatitis B is spread through body fluids. Although usage of contaminated needles was the primary reason for transmission earlier, currently disease is spread mainly through sexual contact.
b is incorrect
Hepatitis B virus mostly affects individuals in the age group of 15-39 years, not middle-aged people. This is because of high-risk activities such as using injected drugs without replacing the needle as well as having multiple sex partners.
c is incorrect
Hepatitis B is prevented by effective vaccine, which is highly recommended in infants.
