Whether hepatitis B (or any disease) is considered epidemic or endemic depends on its prevalence in the population. Hepatitis B is endemic in China where 8-10 % of the population is chronically infected but endemic in the US where the prevalence is less than 1%.
Trichomoniasis is not an epidemic disease. It is endemic.
Diseases that had been epidemic became endemic in urban centers.
"endemic"
PANDEMIC
The causative agent for Hepatitis B is Hepatitis B virus.
An epidemic is a sudden outbreak of a disease (or metaphorically, something that is being compared to a disease, such as an epidemic of crime). A disease can also be described as endemic, which means that there is some incidence of that disease which is always present and doesn't go away.
Hepatitis is inflammation in the liver caused by the virus hepatitis B.
Hepatitis D, also known as delta hepatitis, can only exist as a co-infection with hepatitis B. It requires the presence of the hepatitis B virus to replicate and cause infection. Individuals can become infected with hepatitis D simultaneously with hepatitis B or can acquire it later, but it is dependent on hepatitis B for its existence.
Usually caused by hepatitis B virus.
There's a Hepatitis B vaccine that can prevent it.
Since Hepatitis B vaccine only protects against Hepatitis B, the only thing the vaccine controls is Hepatitis B infections.
