Correct option is A
Measles is an airborne disease transmitted through respiratory droplets when an infected person coughs or sneezes. It does not spread through the feco-oral route, unlike typhoid, cholera, and hepatitis A, which are transmitted through contaminated food and water.
Explanation of Each Option:
· Measles: Measles is caused by the Measles virus and spreads through airborne transmission, not through contaminated food or water. Symptoms include fever, rash, cough, and conjunctivitis.
· Typhoid: Typhoid is caused by Salmonella Typhi and spreads through the feco-oral route, mainly by consuming contaminated food or water. It leads to high fever, weakness, and digestive issues.
· Cholera: Cholera is caused by Vibrio cholerae and is transmitted through contaminated food and water. It results in severe diarrhea and dehydration.
· Hepatitis A: Hepatitis A is a viral infection that spreads through the feco-oral route, primarily due to poor sanitation and contaminated food or water. It affects the liver and causes jaundice, nausea, and fatigue.
