Final answer:
All of the choices are correct for describing chickenpox: it's transmitted by droplet contact, has centripetal lesion distribution, an incubation period of 10 to 20 days, and is characterized by fever and a vesicular rash that occurs in successive crops.
Step-by-step explanation:
Chickenpox is transmitted by droplet contact, and its lesion distribution is centripetal, which means the rash typically starts on the face and progresses to the trunk, then to the extremities, with most lesions forming on the trunk. The statement chickenpox has an incubation of 10 to 20 days is accurate, as the virus has approximately a two-week incubation period. Additionally, chickenpox has fever and vesicular rash that occurs in successive crops, indicating that new waves of blisters can develop as the disease progresses. So, the answer is that all of the provided choices are correct when describing chickenpox.
