Recently recognized and joining Dengue fever as a mosquito-borne illness, CHIKV symptoms range from mild to severe headaches, high fever, muscle pain, possible rash and, most notable, severe joint pains in the arms and legs that can be highly debilitating and prolonged. Patients describe feeling "so ill" that they can't get out of bed. It can take a toll on work productivity and activities of daily living.
To date, no vaccine or treatment is available, and the mechanism for protection has been difficult to grasp. But, according to Cell Host & Microbe, a group of scientists recently isolated human monoclonal antibodies (mAbs) from donors that neutralize CHIKV infectivity. Several of these mAbs exhibited prophylactic and therapeutic activity in a mouse model, suggesting hope for prevention of infection in the future with a vaccine.
While it is too soon to determine if a vaccine is possible, this discover provides a lead for scientists to continue studying the potential for providing protection to "at-risk" individuals.
