A robovirus is a zoonotic virus that is transmitted by a rodent vector (i.e., rodent borne). [1] [2] Roboviruses mainly belong to the virus families Arenaviridae and Hantaviridae. [3] [4] Like arbovirus (arthropod borne) and tibovirus (tick borne) the name refers to its method of transmission, known as its vector.
is the average number of people infected from one other person. For example, Ebola has an of two, so on average, a person who has Ebola will pass it on to two other people.. In epidemiology, the basic reproduction number, or basic reproductive number (sometimes called basic reproduction ratio or basic reproductive rate), denoted (pronounced R nought or R zero), [1] of an infection is the ...

Following infection by rotaviruses there is a rapid innate immune response involving types I and III interferons and other cytokines (particularly Th1 and Th2) [90] which inhibit the replication of the virus and recruit macrophages and natural killer cells to the rotavirus infected cells. [91]
Temperature has the highest effect on virus's survival in water since lower temperatures are the key to longer virus survival. For instance, an article published in 2018 noted that it takes one year for certain viruses including poliovirus and echovirus to decrease by a 5log unit at a temperature of 4 ° C, while it takes only a week to obtain ...
The viral strains fall into two clades: Ravn virus and Marburg virus. [28] The Marburg strains can be divided into two: A and B. The A strains were isolated from Uganda (five from 1967), Kenya (1980) and Angola (2004–2005) while the B strains were from the Democratic Republic of the Congo epidemic (1999–2000) and a group of Ugandan isolates ...
A genetically modified virus is a virus that has been altered or generated using biotechnology methods, and remains capable of infection. Genetic modification involves the directed insertion , deletion , artificial synthesis or change of nucleotide bases in viral genomes.
