Final answer:
Chickenpox, caused by the varicella-zoster virus, usually involves an itchy rash and doesn't often require treatment in children. In severe cases, antiviral medications like acyclovir can be used to reduce symptoms, especially in cases of shingles in adults. Vaccination is an effective preventive measure against both chickenpox and shingles.
Step-by-step explanation:
The manifestations and treatment of herpes type 3 (chickenpox) primarily involve itchy rashes and the potential use of medications to alleviate the symptoms or combat the virus. Chickenpox, caused by the varicella-zoster virus, typically presents as a pustular rash that is concentrated on the trunk of the body. While treatment for chickenpox in children is not usually required, as it is generally mild and self-limiting, antiviral medications such as acyclovir can be used to reduce the severity and length of symptoms in more severe cases such as in adults or immunocompromised patients, as well as in cases of shingles, which is the reactivation of the varicella-zoster virus in adults previously infected with chickenpox.
The vaccine for chickenpox is an effective preventive measure, and there is also a vaccine available for older adults to reduce the likelihood of a shingles outbreak. The correct answer to the question on the manifestations and treatment of chickenpox is therefore 'a) Painful blisters and antiviral medications', as antiviral medications can manage the infection and lessen the symptoms during an outbreak.
