What disease is caused by various viruses and transmitted to humans by mosquitoes and ticks?

• A. Lyme disease
• B. Arthropod-borne encephalitis
• C. West Nile virus
• D. Malaria

Answer: (B)

The disease caused by various viruses and transmitted to humans by mosquitoes and ticks is arthropod-borne encephalitis. This group of viral infections is characterized by inflammation of the brain and can be severe and life-threatening. Several types of arthropod-borne encephalitis viruses, such as Eastern equine encephalitis virus and Western equine encephalitis virus, are spread by mosquito bites. This transmission mechanism is crucial as it distinguishes arthropod-borne encephalitis from other diseases. While Lyme disease is transmitted by ticks, it is caused by a specific bacterium rather than a virus. The West Nile virus is indeed one of the viral infections that can cause encephalitis, but it is more accurate to refer to the broader category of arthropod-borne encephalitis when discussing diseases transmitted by mosquitoes and ticks. Malaria, on the other hand, is caused by a parasite and transmitted specifically by mosquitoes, not by ticks. Thus, arthropod-borne encephalitis encompasses a wider range of viral diseases transmitted by these vectors.
