Bacterial and Viral Infectious diseases

A bacterial infection is a rapid growth of a harmful strain of bacteria on or inside the body. Harmful bacteria can cause a few illnesses like pneumonia, meningitis, and food poisoning. Bacterial infections are one of the main causes of foodborne illness. Common symptoms include nausea, vomiting, diarrhoea, fever, chills, fatigue and abdominal pain. Most of the sexually transmitted diseases (STDs) are caused by harmful bacteria. Most of the times they are not related to any symptoms of the disease but still can cause significant damage to the reproductive system. Bacterial skin infections are generally caused by gram-positive strains of bacteria such as Streptococcus and Staphylococcus. Some of the bacterial infections include boils, impetigo, and folliculitis. Viruses are like hijackers. This can slaughter, damage, or change the cells and make sick. Different viruses attack certain cells in the body such as the liver, respiratory system, or blood.
