Foot-and-mouth disease is a highly contagious infectious disease of extreme sanitary and economic importance to the global livestock industry. The disease is caused by the Foot-and-Mouth Disease Virus (FMDV), which belongs to the Picornaviridae family, genus Aphthovirus. Among the various serotypes of the virus, serotypes O and A are among the most widely distributed and epidemiologically relevant.
FMDV serotypes O and A exhibit high genetic and antigenic variability, which complicates disease control and requires specific surveillance and vaccination strategies. Serotype O is the most prevalent globally, while serotype A is known for its genetic diversity and periodic occurrence in outbreaks with significant public health impact.
FMDV primarily affects cloven-hoofed animals, such as cattle, pigs, sheep, and goats. Clinical signs include fever, the formation of vesicles and erosions in the oral cavity, on the muzzle, tongue, lips, teats, and the interdigital region of the hooves, as well as excessive salivation, lameness, and a sharp decline in milk production and weight gain.
The transmission of serotypes O and A is extremely efficient, occurring through direct contact between infected and susceptible animals, as well as through indirect routes, including aerosols, fomites, vehicles, equipment, people, and contaminated animal products. Its ability to spread rapidly makes foot-and-mouth disease a notifiable disease and a public health emergency.
The impacts associated with serotypes O and A include direct production losses, culling, severe trade restrictions, and high costs for eradication and control programs. The presence of these serotypes can result in the loss of disease-free status for countries or regions, significantly affecting exports.
The prevention and control of foot-and-mouth disease caused by serotypes O and A rely on strict biosecurity measures, active and passive epidemiological surveillance, control of animal movement, and, where applicable, vaccination programs targeting circulating serotypes. Accurate laboratory identification of the serotype is essential for a rapid and effective response to disease outbreaks.
Continuous epidemiological surveillance, combined with laboratory diagnostic capabilities and a coordinated response from public health authorities, is essential to contain the spread of serotypes O and A, protect livestock, and minimize the public health and economic impacts of foot-and-mouth disease.

In this context, Bioperfectus’ rapid test for Foot-and-Mouth Disease (FMDV) serotypes O and A serves as a strategic screening tool to provide immediate support for animal health surveillance. The use of the rapid test enables the rapid identification of suspect animals directly in the field, on farms, at sanitary checkpoints, or during animal health emergencies, facilitating the immediate implementation of containment measures such as isolation, area lockdowns, restrictions on animal movement, and notification to official veterinary services. Thus, the rapid test complements confirmatory laboratory methods, contributing to the early detection of serotypes O and A, the reduction of FMDV spread, and the strengthening of foot-and-mouth disease control and eradication efforts.
