Tropical & Vector-Borne Diseases

Tropical and vector-borne diseases are among the most complex of all infectious diseases to prevent and control. Tropical diseases typically thrive in hot, humid conditions. Many of these pathogens are also vector-borne diseases, transmitted between humans by a vector which is typically a blood-sucking anthropoid (e.g. mosquitoes, ticks, fleas, lice, and mites). Serological point-of-care (POC) diagnostics are the most rapid and convenient methods available for tropical and vector-borne diseases. Tests either detect antigens from the infectious agent or virus-specific IgG/IgM antibodies and include formats such as solid-phase dip-sticks (ELISA), particle agglutination, and lateral flow. Ideally, screening assays should have minimal cross-reactivity with other infectious diseases and have a high sensitivity, especially during the early stages of the infection.
