It is a viral infection.
Shingles is a viral disease related to chickenpox. It results from reactivation of the lifelong infection with the chickenpox virus. Chickenpox can cause myocarditis as a complication. There can be secondary bacterial infection of the skin. Rarely there can be viral encephalitis.
Chickenpox is very contagious, so that 90% of household contacts get the infection. As a result, in unimmunized populations, most adults are immune to chickenpox.
Chickenpox is not an autoimmune disease. Chickenpox is a viral communicable disease.
Chickenpox is an infectious disease, not a genetic disease
When a parasite is growing and multiplying within or on a host, the host is said to have and infection. An infection may or may not result in overt disease. An infectious disease is any change from a state of health in which part or all of the host body is not capable of carrying on its normal functions due to the presence of a parasite or its products.
No, progressive failure of the immune system is not an effect of chickenpox. HIV infection is one communicable disease that causes progressive failure of the immune system.
it is a parasite infection called morgellans syndrome or disease
Natural immunity to chickenpox results from previous infection. There is no other way to be naturally immune to chickenpox. Sometimes, the previous infection may be mild enough that the disease was not noticed. You can become artificially immune to chickenpox by getting chickenpox vaccine.
Chickenpox is not a genetic disease. It's an infectious disease caused by varicella zoster virus.
Chickenpox is caused by a virus. Prions are smaller disease-causing molecules. Viruses, strictly speaking, are not cellular and are not alive, but some people call them microorganisms nevertheless.
Chickenpox is a viral infectious disease. It is not a migration.
