A child was exposed to a disease-causing virus (most likely chicken pox from the Varicella zoster virus) when he was 5 years old. At 12 years old, the child encounters the same virus again. What is most likely expected to happen? Choose one: A. Since macrophages already acted against the pathogen, they will engulf the virus immediately upon exposure. B. After a short lag phase, the child will mount an immune response and serum antibody concentration will increase. C. The pathogen will be neutralized with antibody quickly and the virus will be cleared before symptoms develop. D. The child will be administered antibiotics immediately to remove the disease-causing pathogen.

Step 1
This means his immune system has already encountered this pathogen and has developed specific antibodies against it. This is part of the adaptive immune response, which involves the production of memory cells that remember specific pathogens. Second, the child Show more…

Infection by the varicella-zoster virus causes chickenpox. Evaluate the statements below and assess which are correct regarding the consequences of varicella infection. Individuals who recover from chickenpox are immune to the disease; however, the latent viral genome remains in the cells of the dorsal root ganglia. The varicella-zoster virus may reactivate years later, often as a result of a bacterial infection Shingles occurs when the reactivated virus travels down a sensory neuron and damages the cell resulting in postherpetic neuralgia Postherpetic neuralgia is typically confined to the trunk where the initial chickenpox rash was localized The varicella-zoster virus may reactivate when the individual is immunocompromised due to cancer, advanced age, etc. Individuals who recover from chickenpox are immune to the disease; however, virions can still be detected in the dorsal root ganglia.

Would a person who has never been in contact with the varicella-zoster virus be at risk of developing chickenpox or shingles if they come in close contact with a person with shingles? Explain your reasoning. a. The person is at risk of developing chickenpox. Chickenpox is the first infection with the virus before it enters latency in the host. b. The person is at risk of developing shingles. Shingles is the first infection with the virus before it enters latency in the host. c. The person is at risk of developing chickenpox. Chickenpox is the first infection with the virus that is already latent in the body. d. The person is at risk of developing shingles. The virus enters the person and gets activated when a person with shingles comes in close contact.
