They are mosquito-borne viruses
Arboviruses, or arthropod-borne viruses, are viruses transmitted by insects (vectors) to humans.There are three families of arboviruses:togaviruses (e.g. eastern equine encephalitis, western equine encephalitis)bunyaviruses (e.g. rift valley fever, sandfly fever)flaviviruses (e.g. yellow fever, dengue fever)

Originally known as epidemic polyarthritis, RRV is a member of the Togaviridae family of arboviruses. RRV is transmitted in an animal host-vector-human cycle, where the vector is the mosquito.
Because the arboviruses require an arthropod to pass them along to humans, the most common times of year for these illnesses include summer and fall, when mosquitoes and ticks are most prevalent.

A filterable, ether-sensitive virus was isolated from Anopheles funestus caught in Tanga Province, Tanzania, in 1962. It is unrelated serologically to 43 arboviruses known to occur in Africa and has been named Tanga virus. Antibodies have been found in the sera of East African residents.
Encephalitis can be caused by various pathogens, including viruses, bacteria, fungi, and parasites. The most common viral causes include herpes simplex virus, varicella-zoster virus, and arboviruses like West Nile virus and Japanese encephalitis virus. Bacterial causes can include infections like syphilis or Lyme disease. The specific pathogen often determines the severity, treatment, and prognosis of the disease.
One is west nile virus, caused by mosquitoes.There are more than a dozen viruses that can cause encephalitis, spread by either human-to human contact or by animal bites. Encephalitis may occur with several common viral infections of childhood. Viruses and viral diseases that may cause encephalitis include:mumpsEpstein-Barr virus (EBV)cytomegalovirus infectionHIVherpes simplexherpes zosterherpes Bpoliomosquito-borne viruses (arboviruses)

Yellow fever is caused by the yellow fever virus, which is transmitted to humans through the bites of infected mosquitoes, primarily Aedes aegypti. Encephalitis can be caused by various viruses, including arboviruses and herpes simplex virus, often transmitted through mosquito bites or direct contact. Measles is caused by the measles virus, a highly contagious virus that spreads through respiratory droplets when an infected person coughs or sneezes. Vaccination is key in preventing measles and reducing the risk of severe outcomes from these diseases.

The illness, which can be fatal, is transmitted from one infected person to another by the tsetse fly. While it can occur globally, encephalitis lethargica is especially prevalent in Africa.
