Icosahedral, (+) ssRNA, monopartite, enveloped, 40-50nm, Power (virulence) Most devastating encephalitis disease in the United States Offenses Attacks (Mode of replication, transmission) Natural reservoir in birds. Transmission through Culex mosquitoes that feed mainly on birds Transmitted primarily arthropod borne (mosquito bites) Enter cell through receptor-mediated endocytosis, ph dependent fusion Replication takes place in cytoplasma Fully formed viruses appear within endoplasmic reticulum and released through cell lysis Outcome (Syndrome, Symptoms) Symptoms are usually mild and include fever, headache, tiredness, and dizziness In the most severe cases, encephalitis results leading to death Speed (Incubation Period, Replication Speed) Long latent period, 12 hours or more Defenses Vaccines Currently there are no prospects of vaccine Behavioral (Prevention) Flaviviruses are generally not stable in the environment and can be inactivated by heat, and by disinfectants containing detergents or lipid solvents. Found primarily in Americas, greater awareness of disease in Americas Since transmitted through mosquitoes, protective clothing can stop transmission. When outside, wear long pants and long-sleeved shirts. Individual living in environment conducive for mosquitoes can lead to increased transmission. Stay indoors between dusk and dark. This is when the mosquitoes are most active in their search for food. Mosquitoes breed in stagnant, polluted waters prevent the development of mosquito breeding grounds Spray exposed skin with insect repellent. Treatment There is no specific treatment for St. Louis encephalitis Care of patients centers on treatment of symptoms and complications Prevention is the key Game action Neighbor to the right falls ill with St. Louis Encephalitis and loses a turn. You must now inform all players of how virus is transmitted and preventative methods against St. Louis Encephalitis. |
