Evolution of Infectious Disease infectious disease can be induced by bacteria, viruses, fungi, and parasites. Several examples of infectious diseases are as follows: tuberculosis, chickenpox, mumps, meningitis, measles, and malaria. Infectious diseases can be obtained through many routes of transmission such as inhalation, open wounds, sores, ingestion, sexual intercourse, and insect bites. Author, Paul Ewald used his book to expound upon infectious diseases in humans and animals, explain various routes of transmission as well as epidemiology as a whole. Epidemiology is defined as the study of the onset, distribution, and control of diseases. Evolutionary epidemiology focuses on the distribution of infectious diseases whereas Darwinian
Infectious hematopoietic necrosis virus of different IHNV genotypes, a database called Fishpathogens.eu has been created to store data on different fish pathogens (including IHNV) and their sequences. IHNV is the causal agent of infectious hematopoietic necrosis (IHN) disease of fish and is a negative-sense single-stranded RNA virus. IHNV is a member of the genus "Novirhabdovirus", belongs to the family of "Rhabdoviridae". The North American IHNV isolates are grouped based on the partial glycoprotein (G) gene sequences. The three major IHNV genogroups in North America are designated as U, M, and L for the upper, middle and lower portions of IHNV geographical range in North
