A. Vectors
B. Air and physical contact
C. Contaminated food and water
D. Droplets seen in air

Answer 1

The disease Ascariasis got its name from the roundworm called Ascaris. The scientific name is Ascaris lumbricoides. It is the parasite that infects the intestine of the human and is said to be the most common worm infection in human beings. These roundworms are a kind of parasitic worm and the infections caused by these worms are most common.

Complete answer:
By now, you are clear with the basic information regarding the worm. Let us understand its physiology and mode of infection. This worm is native to the intestine and produces eggs there, which are further passed out through faeces. When the other person ingests these eggs, he is said to be infected with ascariasis. This can happen when the faeces are used as fertilizer to the soil in gardens or fields and when a person unknowingly touches this soil and doesn't wash the hands properly or when the eatables are not properly washed , the eggs can enter the human body. So, healthy and clean food must be taken. This infection is said to be more common where proper sanitation and hygiene is not followed. The disease cannot be spread through physical contact and any vector is not involved in transmission. The disease is not caused by a virus, so it cannot spread through infected droplets. This is the disease which spreads through contaminated food or water.

Hence, the correct option is C.

Note:
The infected person does not show any distinct symptoms ,there may be slight abdominal discomfort. As the eggs pass from the intestine, these can be found in the faeces and hence diagnosed using the sample of stool. The disease can be effectively managed by implementing safe sewage disposal systems away from the crowd.
