Analysis of Zika virus dynamics with sexual transmission route using multiple optimal controls

Zika Virus and Sexual Transmission: A New Route of Transmission for Mosquito-borne Flaviviruses


Beginning in 2015, concern over a new global epidemic has spread in the media, governmental agencies, legislative bodies and the public at large. This newly emerging threat has been reported to cause symptoms ranging from mild fever, rash, and body aches, to severe birth defects and acute onset paralysis. The causative agent of this disease, Zika virus, is closely related to two other important...

Prevention of sexual transmission of Zika virus.

Based on this new evidence, the recommended length of time for safer sex practices for asymptomatic males returning from areas with active Zika virus transmission was extended from 8 weeks to 6 months. This is the same length of time as is recommended for symptomatic males. This recommendation now also applies to females, whether or not they have had symptoms. The 6 month duration of safer sexu...

Potential Sexual Transmission of Zika Virus

In December 2013, during a Zika virus (ZIKV) outbreak in French Polynesia, a patient in Tahiti sought treatment for hematospermia, and ZIKV was isolated from his semen. ZIKV transmission by sexual intercourse has been previously suspected. This observation supports the possibility that ZIKV could be transmitted sexually.

Mathematical Model for Transmission Dynamics of Hepatitus C Virus with Optimal Control Strategies

An epidemic model with optimal control strategies was investigated for Hepatitus C Viral disease that can be transmitted through infected individuals. In this study, we used a deterministic compartmental model for assessing the effect of different optimal control strategies for controlling the spread of Hepatitus C disease in the community. Stability theory of differential equations is us...
