Trichomoniasis is a sexually transmitted infection (STI) which is most often spread through vaginal, oral, or anal sex. It can also spread through genital touching. People who are infected may spread the disease even when symptoms are not present.
The manufacture of US paper currency is handled by the Bureau of Engraving and Printing (BEP). The main facility is in Washington, DC. There is a also a facility in Fort Worth, TX that is more recent (opened in 1991).
The ordinary paper that consumers use throughout their everyday life such as newspapers, books, cereal boxes, etc., is primarily made of wood pulp; however, United States currency paper is composed of 75 percent cotton and 25 percent linen. This is what gives United States currency its distinct look and feel. For denominations of $5 and above, the security thread, and portrait or numberal watermarks are already built into the paper when it is received. For the $100 note, a 6mm wide 3-D security ribbon is woven into the paper.
