8. A Treat for Mosquitoes
Blood test
Rajat is back at school today. He had been absent for
many days. “How are you now?” asked Aarti. “I’m
alright,” Rajat replied softy.
Jaskirat: You must have played a lot while you were
at home.
Rajat : Who wants to play when you have fever! On
top of it I had to take a bitter medicine! I even had a
blood test.
Jaskirat: A blood test? Why? It must have been very
painful.
Rajat: Actually, when the needle pricked my finger, it
felt like an ant bite. They took 2-3 drops of blood, and
sent it for testing. That’s how we came to know that I
had malaria.
Nancy: But you get malaria when a mosquito bites you.
Rajat: Yes, but we find out by the blood test.
Jaskirat: There are a lot of mosquitoes in my house
these days, but I did not get malaria.
Nancy: Who says that every mosquito bite causes
malaria? Malaria spreads only by the disease carrying
mosquitoes.
Aarti: All mosquitoes look the same to me.
Rajat: There must be some difference.

Anaemia–What’s that?
Aarti: You know, I also had to get a blood test done. But they took
a syringe full of blood. The blood test showed that I had anaemia.
Rajat: What is that?
Aarti: The doctor said that there is less ‘haemoglobin’ or iron in
the blood. The doctor gave some medicines to give me strength.
He also said that I should eat jaggery, amla and more green leafy
vegetables, because these have iron.
Nancy: How can there be iron in our blood?
Jaskirat: There was something about this in the newspaper
yesterday.
Rajat (laughing) : So then you ate iron or what?!
Aarti: Silly! This is not the iron used to make these keys. I don’t
know exactly what it was. After I ate a lot of vegetables and
whatever the doctor had said, my haemoglobin went up.
Teacher’s Note : You can bring a blood report in the class and discuss with the children.

Anaemia common in Delhi school
17 November, 2007 - Thousands
of children studying in the
Municipal Corporation schools in
Delhi suffer from anaemia. This
is affecting both their physical as
well as mental health. Due to
anaemia, children do not grow
well, and their energy levels are
low. This also affects their ability
to study properly. Now health
check ups are being done in the
schools and health cards are
being made for all the children.
Anaemic children are also being
given iron tablets.
