Different factors involved in increasing the risk of infectious diseases caused by genetic and environmental changes. Due to high risk of infectious diseases such as chronic kidney disease, osteoarthritis, osteoporosis, Alzheimer's disease, cataracts, advances have been made in the fields of molecular sciences and engineering technology for highly effective tools and high-throughput omics technologies. Ebola virus is the most contagious as compared to the other viruses colds, influenza, or measles. Pathogenic bacteria are involved in causing of infectious diseases. Hib disease is the serious public health concern disease caused by Haemophilus influenza. Norwalk virus also causes serious abnormalities in the digestive system that ultimately leads to muscle cramp. Antimicrobial resistance have been challenging in the fields of biomedical sciences. Sequencing of bacterial genomes helpful for track the different status of fates of mutations that rise and fall through indication of multiple replicates. Genetic engineering based biomedical therapies needed to understand the target microbial cell, protein factory that secreted the variety of products.
