Answer:
1. Malaria: It is transmitted by infected mosquitoes when you get bitten by a mosquito which carries the malaria parasite- the parasite enters your bloodstream. It is then carried to your liver, where it multiplies.
2. Common cold: It is transmitted by virus- infected airborne droplets or by direct contact with infected secretion.
3. Tetanus: It is not transmitted from person to person. A person usually becomes infected with tetanus when dirt enters a wound or a cut.
4. Typhoid: The typhoid bacillus is transmitted by consumption of contaminated food or water.
