typhoid is spread by

Typhoid fever is primarily spread through the ingestion of food or water contaminated with Salmonella Typhi, the bacterium responsible for the illness. Yes, you’re right to be concerned about your local water supply; contaminated water is a significant mode of transmission, especially in areas where sanitation may be compromised. If your brother has had contact with contaminated water or consumed food prepared with it, that could well be how he contracted the infection. Foodhandlers who carry the bacteria can unwittingly spread it if they handle food without proper hand hygiene, which can occur even if the individuals don’t show symptoms themselves. Typically, typhoid isn’t spread by casual contact — like touching contaminated surfaces — as it’s not as easily transmissible as, say, the flu. However, practicing good hygiene is crucial; handwashing with soap and safe water is effective in preventing the spread. To reduce the risk of transmission, ensure everyone in the household washes hands thoroughly before eating and after using the toilet. Boil or treat drinking water and avoid raw foods that may have been washed in untreated water. Your brother should maintain good personal hygiene and avoid handling food for others while recovering. Given he’s on treatment, improvements should follow as antibiotics work to clear the infection. Be watchful for any red-flag symptoms like persistent high fever, severe diarrhea, or confusion, and seek medical attention swiftly as these can be serious complications. Safe food and water practices, alongside vaccination where available, can greatly help in prevention.
