Human Immunodeficiency Virus (HIV) Subtype Surveillance of African-Born Persons at Risk for Group O and Group N HIV Infections in the United States

摘要: A population-based surveillance registry was used to identify human immunodeficiency virus (HIV)-infected persons in the United States at increased risk for group O and N infections (those born or near African countries where infection has been reported). Of 155 eligible subjects, 37 gave samples. By phylogenetic serologic analysis, 32 were infected with M (16 subtype A, 5 B, 7 C, 1 each subtypes D, F2, G, recombinant A/J) 2 but none virus. For 3, samples could not be typed by serology amplified polymerase chain reaction using M-, O-, N-specific primers. In States, HIV is uncommon; no case of found. African-born may have strains typical their birth country. Ongoing allow early identification novel emerging strains.
