Std 5 EVS 1 Chapter 23 Question Answer

1. What’s the solution?

Question 1.
You are hungry, but the food has been left uncovered.
Answer:
Heating kills all the disease germs present in the food. So if food is uncovered then one should heat (warm) the food and then eat it when hungry. Eating warm food is always good for health.

2. Use your brain power!

Question 1.
Which method of preventing the breeding of mosquitoes will you recommend for your surroundings – not allowing water to stagnate or spraying insecticides on the water? Why?
Answer:
First of all it is better not to allow water to stagnate. Hence I would recommend this method for preventing breeding of mosquitoes. However if there are nullahs or gutters in the surrounding area then spraying insecticide on water will be recommended to kill the mosquito larvae growing in water. Therefore both the methods need to be applied sometimes.

3. Answer the following in one or two sentences:

Question (a)

Answer:
When diseases spread from one person to another person, they are called infectious diseases.

Answer:
Diseases spread through mediums like food, water, air and insect bite. Sometimes it also spreads by coming in direct contact with a diseased person.

Question (c)
What happens when there is an epidemic of disease?
Answer:
When many people in one area get the same infectious disease at the same time, we say there is an epidemic of the disease. During an epidemic air and water gets contaminated with the disease germs and the disease spreads rapidly. Contaminated water also contaminates the food. If the epidemic is severe many people become serious and need to be hospitalised. To control the epidemic one needs to maintain hygiene and a clean surrounding.

Question (d)
What is vaccination?
Answer:
When a person is given a vaccine against a specific disease, he develops resistance to that disease. This process of giving vaccine is called vaccination. Whooping cough diphtheria and tetanus called triple vaccine is given.

Oral Polio	Against Polio	Within 2 weeks
Triple vaccine	Against Diphteria, whooping cough and tetanus	After 6 weeks baby is born

Triple vaccine is repeated twice again after 10 weeks and 14 weeks after the baby is bom. Hep. B vaccine is also repeated twice after 4 weeks and 8 weeks after birth. After completing a year the baby is given vaccine against measles, mumps and rubella. It is called MMR vaccine.

Jaundice	Jaundice	Conjunctivitis

6. Give reasons.

Question (a)
When there is an epidemic of cholera, we should boil water before drinking.
Answer:
Sometimes water gets mixed with faeces of person who is suffering from the cholera and it gets contaminated. When people drink this contaminated water an epidemic of cholera spreads.
Boiling the water kills the germs causing the disease and hence one is prevented from getting cholera.
Therefore during an epidemic of cholera one should boil water and drink.

Question (b)
We should not allow puddles of water to stand in our surroundings.
Answer:
When water stagnates in a puddle, mosquitoes lay eggs in the water and they increase in number. Mosquito bite spread malaria germs and people suffer from malaria. To prevent people from getting malaria mosquitoes should be stopped from breeding. To prevent mosquitoes from breeding we should not allow puddle of water to stand in our surrounding.

(Note : Fleas are found on the bodies of pets like dogs, cat and also on rhodents like rats.)

Answer:
Gastro or diarrhoea spreads through contaminated3 food. When we eat this food the disease spread is called food poisoning.

Question 5.
Why should food always be kept covered?
Answer:
When some flies sit on our food, the germs enter the food. Later when we eat this food the germs enter our body, so we must always cover the food.

Question 6.
What is an epidemic?
Answer:
When many people in one area get the same infectious disease all at the same time, we say that there is an epidemic of the disease.

Question 7.
What precaution can be taken to prevent the spread of tuberculosis?
Answer:
The spittle of a person who has tuberculosis is collected in a vessel and covered with a germicide like phenyl. Such precautions can help to prevent the disease from spreading.

Give scientific reasons:

Question 1.
Doctors give tetanus vaccine after getting a cut or wound while handling a sharp instrument or after falling down and getting bruised badly while playing.
Answer:
Tetanus germs are present in the soil, dung and dust. The sharp instrument may be dirty, so it may carry the tetanus germs. These germs may then spread though the wound and cause disease. To prevent tetanus germs from spreading doctors give the vaccine which help us develop resistance against this disease.

Question 2.
A person suffering from a disease should cover the mouth when sneezing or coughing.
Answer:
Disease causing organisms are present in the spit or saliva of the person. When they sneeze or cough these gems spread in the air and cause disease in other people. To prevent the spread of disease through the air a person suffering from a disease should cover the mouth while sneezing or coughing.

Question 3.
Before eating or handling food one should wash the hands using soap and water.
Answer:
Soap kills the germs which cause diseases and water washes them away. If our hand is dirty then they may contain disease causing germs. If we handle food, or eat food without washing, the germs will enter the food and contaminate it with these germs. This can cause intestinal diseases or food poisoning. Hence it is advised that one should wash the hands using soap and water before eating or handling food.

Question 4.
People who are suffering from tuberculosis or swine flu are quarantined and kept in hospitals.
Answer:
The diseases like tuberculosis and swine flu are infectious. They spread through air easily. Also the germs spread cause disease in a healthy person if the healthy person comes in contact directly with the diseased person. In hospitals there are separate wards for such diseased people, where extra care and precautions are taken to prevent spread of diseases. Therefore patients suffering from these diseases are quarantined and kept in hospital.

Can you tell:

Question 1.

Answer:
