The symptoms of chickenpox usually last between five and 10 days. In addition to red spots on the body, people with the virus may experience fever, loss of appetite, headache and tiredness, states Mayo Clinic. The raised spots last for a few days, after which they form blisters before crusting and scabbing over. The varicella-zoster virus causes chickenpox, which spreads quickly through direct contact with an infected person or through air dispersal via coughing or sneezing. People who have not had chickenpox, those who are not vaccinated, and those who live or work around children are at risk of contracting the virus.

Hives, or urticaria, cause red spots and welts that are itchy and vary in size, notes Mayo Clinic. Most people who get hives recover after 24 hours, though people with chronic hives may have them for months or years. Conditions that can lead to hives include reactions to foods such as shellfish or peanuts, common allergens such as latex and pollen, underlying medical conditions, and medications such as penicillin and blood pressure medications.
