Hepatitis C is a global public health concern that infects millions of people worldwide. The continual discovery of new genotypes and subtypes of hepatitis C virus (HCV) is an indication of a persistent molecular evolution of the virus. This remains a concern in the efforts towards hepatitis C elimination, as effective management of the disease is, in part, dependent on the HCV genotype responsible for the infection. Accurate HCV screening and quantification using rapid but highly sensitive and reliable methods are crucial for the diagnosis and subsequent management of HCV-related diseases. Thus, this article discusses HCV and the common methods employed for HCV detection and genotyping. While nucleotide sequencing and phylogenetic analysis of core/E1 and NS5B region are regarded as the gold standard and the most recommended method used for HCV genotyping, electrochemical sensors are being explored for their rapidity.

Chikungunya is an infection caused by chikungunya virus which at present has spread to new countries and continents. Chikungunya is associated with self-limiting and non-fatal infection in the past. However, in recent times, increased severity of the disease has been reported resulting in health and economic burden. The threat and burden of chikungunya would grow in future in the absence of specific antiviral or vaccine to control or eliminate the infection. This review discusses chikungunya in general including transmission of its etiological agent and clinical manifestations of the disease. Subsequently, management and treatment of chikungunya virus will be reviewed with particular emphasis on natural products or their active compounds with potential anti-chikungunya virus activities.
