Summarize this article for a 10 year old
Henipavirus is a genus of negative-strand RNA viruses in the family Paramyxoviridae, order Mononegavirales containing six established species,[1][2] and numerous others still under study.[3] Henipaviruses are naturally harboured by several species of small mammals, notably pteropid fruit bats (flying foxes), microbats of several species,[4] and shrews.[5][6] Henipaviruses are characterised by long genomes and a wide host range. Their recent emergence as zoonotic pathogens capable of causing illness and death in domestic animals and humans is a cause of concern.[7][8]

In 2009, RNA sequences of three novel viruses in phylogenetic relationship to known henipaviruses were detected in African straw-colored fruit bats (Eidolon helvum) in Ghana. The finding of these novel henipaviruses outside Australia and Asia indicates that the region of potential endemicity of henipaviruses may be worldwide.[9] These African henipaviruses are slowly being characterised.[10]
Nipah and Hendra henipaviruses are both considered category C (USDA-HHS overlap) select agents.[11]
