Final answer:
Fifth Disease, also known as Erythema Infectiosum, is caused by Parvovirus B19. It is characterized by a distinct "slapped cheek" facial rash and a second rash on the body, following cold-like symptoms. The disease is self-limiting and usually recedes within a few weeks.
Step-by-step explanation:
The agent responsible for causing Erythema Infectiosum, or Fifth Disease, is Parvovirus B19. Fifth Disease is a highly contagious infection, particularly common in children. The disease is spread through respiratory secretions, such as saliva or nasal mucus, when an infected person coughs or sneezes.
After contracting the virus, a person may initially experience cold-like symptoms, including a headache, fever, and upset stomach. These symptoms are followed by the appearance of a distinct red rash on the face, also known as "slapped cheek" rash, and then a second rash may develop on the body. While the rash can be uncomfortable, it typically resolves on its own within a span of one to three weeks.
It is important to note that other common and similar viral infections are caused by different agents. For instance, Roseola is usually caused by Human herpesvirus 6 (HHV-6), while other skin infections might be due to viruses such as Human papillomavirus or Rubella.
