To determine:
Alternate ways to protect from mosquito-borne pathogens without using repellents.
Case summary:
In the given scenario, an old man from Italy with symptoms of joint pain, fever, nausea, and difficulty in breathing goes to the doctor. Thus, relating the symptoms with the equine encephalitis virus, the doctors now could diagnose the virus as chikungunya virus.

- In 1969, a 16-year-old boy named Robert Rayford was admitted to a hospital in St. Louis, Missouri. He was weak, emaciated, rife with stubborn infections, and riddled with rare cancerous lesions known as Kaposi’s sarcoma, a skin disease found in elderly men of Mediterranean descent. Three months after he was admitted, he died of pneumonia. More than ten years later, similar cases were seen in states like New York and California. It was eventually discovered that young Robert Rayford actually had AIDS. Using 2-3 pieces of evidence from the text, explain why Robert Rayford ended up dying from pneumonia.arrow_forwardPeople with herpes simplex type 1 viruses often getmouth sores when they have a cold or similar infection.How might this location benefit the virus?arrow_forwardWhat do influenza virus and Ebola virus have in common?In what ways do their modes of transmission differ?arrow_forward
