True about Arboviruses is
**Core Concept**
Arboviruses, also known as arthropod-borne viruses, are a group of viruses transmitted primarily through the bites of infected arthropods like mosquitoes and ticks. These viruses cause a range of diseases in humans, including yellow fever, dengue fever, Zika virus disease, and West Nile virus infection.
**Why the Correct Answer is Right**
Arboviruses are classified into four main families: Togaviridae, Flaviviridae, Bunyaviridae, and Reoviridae. The Flaviviridae family includes viruses like yellow fever, dengue fever, and Zika virus, which are primarily transmitted through the bites of infected mosquitoes. These viruses replicate in the mosquito vector before being transmitted to humans, where they can cause a range of clinical manifestations, from mild fever to severe neurological disease.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not specify the correct family or classification of arboviruses.
**Option B:** This option is incorrect because it does not accurately describe the primary mode of transmission of arboviruses.
**Option C:** This option is incorrect because it does not accurately describe the range of diseases caused by arboviruses.
**Clinical Pearl / High-Yield Fact**
Arboviruses can be transmitted through other means, such as organ transplantation or laboratory accidents, in addition to arthropod bites. This highlights the importance of proper infection control measures in healthcare settings.
**Correct Answer: D**.
