Chickenpox is an infectious disease caused by the Varicella-Zostervirus (VZV), this is a virus in the family of Herpesviridae. It’s characterized by fever, skin rash and mucocutaneous rash. Chickenpox is widely distributed disease with varying in age, seasons, climate, and resident of people . Mother-to-child transmission of the virus can occur during pregnancy, during delivery and after birth. In people who have had chickenpox, after the cure, a few viruses exist in the nerves sensing the spine in the form of latent, silent. When conditions are favorable (triggers) such as immunodeficiency, stress, radiation therapy, cancer, HIV infection ... the virus reacts, multiplies and spreads, causing inflammation and necrosis of the nerve in shingles (Zona). Chickenpox is a benign disease but it can also cause many complications in severe cases and which is not properly treated. Complications of dermatitis due to bacterial superinfection, the peanut note to pus, when cured can leave scar. In patients with severe malnutrition, nodules may be necrotic. The most severe complication is encephalitis, meningitis that are very dangerous, which can cause dead if delayed to hospital and emergency care is not timely. The disease can spread rapidly in the community, but there are active measures to prevent chicken pox, which is vaccination. Key words: Chickenpox, Varicella-Zostervirus (VZV)

AbstractThe present work used fractional model of Casson fluid by utilizing a generalized Fourier’s Law to construct Caputo Fractional model. A porous medium containing nanofluid flowing in a channel is considered with free convection and electrical conduction. A novel transformation is applied for energy equation and then solved by using integral transforms, combinedly, the Fourier and Laplace transformations. The results are shown in form of Mittag-Leffler function. The influence of physical parameters have been presented in graphs and values in tables are discussed in this work. The results reveal that heat transfer increases with increasing values of the volume fraction of nanoparticles, while the velocity of the nanofluid decreases with the increasing values of volume fraction of these particles.
