Sexual abuse, also referred to as molestation, is forcing undesired sexual behavior by one person upon another. When that force is immediate, of short duration, or infrequent, it is called sexual assault. The offender is referred to as a sexual abuser or (often pejoratively) molester. The term also covers any behavior by any adult or older adolescent towards a child to stimulate any of the involved sexually. When the victim is younger than the age of consent, it is referred to as statutory rape or child sexual abuse.
Spousal sexual abuse is a form of domestic violence. When the abuse involves forced sex, it may constitute rape upon the other spouse, depending on the jurisdiction, and may also constitute an assault.
Child sexual abuse is a form of child abuse in which a child is abused for the sexual gratification of an adult or older adolescent. It includes direct sexual contact, the adult or otherwise older person engaging indecent exposure (of the genitals, female nipples, etc.) to a child with intent to gratify their own sexual desires or to intimidate or groom the child, asking or pressuring a child to engage in sexual activities, displaying pornography to a child, or using a child to produce child pornography.
Influenza A virus subtype H5N1, also known as A(H5N1) or simply H5N1, is a subtype of the influenza A virus which can cause illness in humans and many other animal species. A bird-adapted strain of H5N1, called HPAI A(H5N1) for highly pathogenic avian influenza virus of type A of subtype H5N1, is the highly pathogenic causative agent of H5N1 flu, commonly known as avian influenza ("bird flu"). It is enzootic (maintained in the population) in many bird populations, especially in Southeast Asia. One strain of HPAI A(H5N1) is spreading globally after first appearing in Asia. It is epizootic (an epidemic in nonhumans) and panzootic (affecting animals of many species, especially over a wide area), killing tens of millions of birds and spurring the culling of hundreds of millions of others to stem its spread. Many references to "bird flu" and H5N1 in the popular media refer to this strain.
According to the World Health Organization and United Nations Food and Agriculture Organization, H5N1 pathogenicity is gradually continuing to rise in endemic areas, but the avian influenza disease situation in farmed birds is being held in check by vaccination, and so far there is "no evidence of sustained human-to-human transmission" of the virus. Eleven outbreaks of H5N1 were reported worldwide in June 2008 in five countries (China, Egypt, Indonesia, Pakistan and Vietnam) compared to 65 outbreaks in June 2006 and 55 in June 2007. The global HPAI situation significantly improved in the first half of 2008, but the FAO reports that imperfect disease surveillance systems mean that occurrence of the virus remains underestimated and underreported. In July 2013 the WHO announced a total of 630 confirmed human cases which resulted in the deaths of 375 people since 2003.
