Arboviruses are a group of viruses that are transmitted by arthropods such as mosquitoes, ticks, and sandflies. The spelling of "arboviruses" follows the International Phonetic Alphabet (IPA) phonetic transcription system. The "ar" sound is represented by /ɑː/, the "b" sound by /b/, and the "o" sound by /ɔ/. The "v" sound is represented by /v/ and the "i" sound by /ɪ/. Lastly, the "r" sound is represented by /r/ and the "u" sound by /ˌjuː/. The result is the pronunciation /ɑːrbɔːˈvaɪrəʊuːzɪz/.
Arboviruses, short for arthropod-borne viruses, are a group of viruses that are transmitted to humans and other animals primarily through the bites of infected arthropods, such as mosquitoes, ticks, and sandflies. These viruses are classified in the family Flaviviridae and Togaviridae, which includes well-known arboviruses like dengue virus, Zika virus, West Nile virus, and chikungunya virus, among others.
Arboviruses are typically maintained in nature through a complex transmission cycle involving both vertebrate hosts (including animals and birds) and arthropod vectors. Infected mosquitoes, for example, acquire the virus through feeding on an infected host and subsequently transmit it to a new host during subsequent feedings. The ability of these viruses to replicate and circulate within both the arthropod vector and the vertebrate host makes them well-adapted to persist in different ecological habitats across the globe.
In humans, arboviral infections can range from asymptomatic or mild flu-like illnesses to more severe diseases, sometimes leading to long-term neurologic problems or even death. Symptoms may include fever, headache, joint pain, muscle aches, rash, and fatigue. The severity of the illness can vary depending on the specific arbovirus and individual factors such as age, immune status, and overall health.
Prevention and control of arboviral infections primarily focus on vector control measures, such as reducing mosquito populations and minimizing contact between humans and infected vectors. Additionally, research towards the development of vaccines, antiviral drugs, and improved diagnostic tools continues to be a crucial part of managing and addressing arboviral diseases.
The word "arbovirus" is derived from the combination of two terms: "arbo" and "virus".
1. "Arbo" is an abbreviation of "arthropod-borne". It comes from the Greek word "árthron", meaning "joint", and "pous", meaning "foot". "Arbo" refers to organisms transmitted by arthropods, such as mosquitoes, ticks, and sandflies.
2. "Virus" comes from the Latin word "vīrus", meaning "poison" or "slimy liquid". It originally referred to venom or any poisonous substance. Over time, it was specifically associated with infectious agents that can replicate inside living cells.
Combining these two terms, "arbovirus" refers to viruses that are transmitted by arthropods.
