This document discusses guidelines for disinfection and sterilization in healthcare facilities. It outlines three categories of medical devices based on infection risk: critical, semicritical, and noncritical. Critical devices that contact sterile tissue require sterilization. Semicritical devices that contact mucous membranes require at minimum high-level disinfection to kill all microbes except small numbers of bacterial spores. Noncritical devices that contact intact skin require low-level disinfection. The document provides examples of appropriate disinfection/sterilization methods for each category of device. Adherence to these guidelines is important for reducing healthcare-associated infections.
Sterilization is used to destroy all microbial life through physical or chemical processes. It is important for reducing deaths from infection, improving surgical techniques and health conditions. Sterility assurance levels define the probability of an item remaining non-sterile after sterilization. Common sterilization methods include heat, steam, radiation, filtration, ethylene oxide, and hydrogen peroxide. Regulations and standards from organizations like the ISO aim to harmonize sterilization practices globally.

Typhoid fever is a life-threatening illness caused by Salmonella typhi bacteria. It commonly affects about 21.5 million people per year in developing countries. Salmonella bacteria are gram-negative rods that can cause diseases like typhoid fever, paratyphoid fever, and food poisoning. Salmonella enter the body through contaminated food or water and cause illness by invading the intestinal wall and spreading to other organs. Laboratory diagnosis of typhoid fever involves culturing Salmonella from the blood, bone marrow, urine or stool and performing serological tests to detect antibodies produced in response to infection. Treatment may involve antibiotics like chloramphenicol or fluoroquinolones, though drug resistance has become a challenge in some areas
