It has attracted international medical and political attention as well as large-scale funding since it was identified in the 1980s. There are three main stages of HIV infection: acute infection, clinical latency and AIDS. The initial period following the contraction of HIV is called acute HIV, primary HIV or acute retroviral syndrome. Many individuals develop an influenza-like illness or a mononucleosis-like illness 2–4 weeks after exposure while others have no significant symptoms. Symptoms occur in 40–90% of cases and most commonly title: Infection text: although they have had little or no contact with the agent, these natural antibodies confer specific protection to adults and are passively transmitted to newborns. The organism that is the target of an infecting action of a specific infectious agent is called the host. The host harbors and agent in a mature, or sexually active stage phase called the definitive host. The intermediate host comes in contact during the larvae stage. A host can be anything living and can attain to asexual and sexual reproduction. The clearance of the pathogens, either treatment-induced or spontaneous, it can be influenced by the title: History of HIV/AIDS text: History of HIV/AIDS AIDS is caused by a human immunodeficiency virus (HIV), which originated in non-human primates in Central and West Africa. While various sub-groups of the virus acquired human infectivity at different times, the global pandemic had its origins in the emergence of one specific strain – HIV-1 subgroup M – in Léopoldville in the Belgian Congo (now Kinshasa in the Democratic Republic of the Congo) in the 1920s. There are two types of HIV: HIV-1 and HIV-2. HIV-1 is more virulent, is more easily transmitted and is the cause of the vast majority of HIV infections globally. The title: Infection text: Infection Infection is the invasion of an organism's body tissues by disease-causing agents, their multiplication, and the reaction of host tissues to the infectious agents and the toxins they produce. Infectious disease, also known as transmissible disease or communicable disease, is illness resulting from an infection. Infections are caused by infectious agents including viruses, viroids, prions, bacteria, nematodes such as parasitic roundworms and pinworms, arthropods such as ticks, mites, fleas, and lice, fungi such as ringworm, and other macroparasites such as tapeworms and other helminths. Hosts can fight infections using their immune system. Mammalian hosts react to infections with an title: Virus text: to the specific viral infection. Some viruses, including those that cause AIDS and viral hepatitis, evade these immune responses and result in chronic infections. Several antiviral drugs have been developed. The word is from the Latin neuter "vīrus" referring to poison and other noxious liquids, from 'the same Indo-European base as Sanskrit "viṣa" poison, Avestan "vīša" poison, ancient Greek "ἰός" poison', first attested in English in 1398 in John Trevisa's translation of Bartholomeus Anglicus's "De Proprietatibus Rerum". "Virulent", from Latin "virulentus" (poisonous), dates to c. 1400. A meaning of "agent that causes infectious disease" is first recorded in 1728, before
