Rift Valley fever virus (RVFV) is a globally important mosquito-borne virus that can also be directly transmitted via aerosolization of body fluids from infected animals. RVFV outbreaks cause mass mortality of young livestock and abortions in animals. In most severe human cases, the disease can progress to hemorrhagic fever and encephalitis, leading to death. RVF has a significant economic impact due to the loss of livestock that is a great challenge for people who depend on animals for income and food. Several vaccines are available for animal use, but none are yet licensed for use in human populations. This situation emphasizes the need to have robust and efficient diagnostic methods that can be used for early case confirmation, assessment of seroprevalence, and virus surveillance as well as vaccine efficacy evaluation. Despite the existence of different diagnostic methods for RVFV, we still have untimely reporting or underreporting of cases, probably due to lack of appropriate surveillance systems or diagnostic tools in some endemic countries. Here, we describe different methods available for detection and diagnosis of RVFV.
