Bee products as alternatives in the treatment of viral infections

Journal of the Science of Food and Agriculture, Volume 106, Issue 1, Page 33-54, 15 January 2026.
Abstract Medicines used in the treatment of viral infections usually reduce symptoms. There is a need to develop drugs that inhibit the viruses and do not merely relieve the symptoms. Natural bee products possess many pharmacological properties and are widely used in folk medicine. There are many studies on the antibacterial effects of bee products but

Effects of Chikungunya virus immunity on Mayaro virus disease and epidemic potential [PDF]

Scientific Reports, 2019
AbstractMayaro virus (MAYV) causes an acute febrile illness similar to that produced by chikungunya virus (CHIKV), an evolutionary relative in the Semliki Forest virus complex of alphaviruses. MAYV emergence is typically sporadic, but recent isolations and outbreaks indicate that the virus remains a public health concern.
