Enterovirus and coxsackievirus A can be recovered from conjunctival scrapings of patients with AHC during the first 3 days of illness. Isolation rates are somewhat higher for enterovirus than for coxsackievirus. Less than 5% of throat swab or fecal specimens have been positive for either virus. Echovirus 70 is the chief cause of this disease. Coronaviruses in humans remain limited to the upper respiratory tract. Reoviruses in the United States are responsible for acute respiratory and gastroenteritis infections. RSV is a paramyxovirus involved primarily in respiratory illnesses. Rhinoviruses are common cold viruses.
During a routine physical examination, you notice that your patient, a 35-year-old avid surfer, has spots of abnormal pigmentation on two of her fingers. You explain to your patient that long-term exposure to the sun increases the risk of neoplastic changes and that you would like to perform biopsies to verify the nature of the abnormal pigmentation. Referring to Fig. 1-7, cells from which layer of the epidermis are most vulnerable to neoplastic changes due to long-term exposure to the sun?
