- "Although the reported number of cases varies, arboviruses cause substantial morbidity in the United States each year. Cases occur sporadically, with epidemiology varying by virus and geography. Weather, zoonotic host, vector abundance, and human behavior all influence when and where arboviral outbreaks occur, making it difficult to predict locations and timing of cases and underscoring the importance of surveillance in identifying outbreaks and informing prevention efforts." Which of the following means the same as "Cases occur sporadically"? O Cases are caused by fungal spores. O Because of vector transmission, there is a steady rate of arboviral cases each year O Outbreaks occur unpredictably QUESTION 8 "Although the reported number of cases varies, arboviruses cause substantial morbidity in the United States each year.
