5.1. Describing illnesses and diseases and pandemics
5.1.1 Learning activity: Reading and Text analysis
• Text: Types of diseases in Rwanda
• Text: Types of diseases in Rwanda
There are different types of diseases in Rwanda. Some diseases affect
the majority of Rwandans. Others affect only a small number of the
population. The most common diseases in Rwanda today are malaria,
HIV/AIDS, tuberculosis, typhoid or typhoid fever. Many Rwandans also
suffer from amoebic dysentery, Hepatitis B and C and the common cold
Some transmissible diseases, like typhoid and amoebic dysentery, are
waterborne. This means you get these diseases when you drink water
that is not clean and boiled. Diseases like tuberculosis and the common
cold are airborne. The bacteria or viruses are ejected into the air via
coughs or sneezes. When you breathe in this air, you become infected
Hepatitis B and C and HIV/AIDS are transmitted through body fluids.
Infections and diseases, such as hepatitis are most often carried through
the semen and blood of infected persons. Malaria is transmitted through
the bite of a female anopheles’ mosquito. It injects infected blood into
your body when it bites you.
Transmissible diseases are caused by causative agents. Typhoid, amoebic
dysentery and tuberculosis are caused by bacteria. Hepatitis B and C,
HIV/ AIDS and the common cold are caused by viruses. Malaria is caused
by a parasite called plasmodia.
Other diseases are sometimes referred to as lifestyle diseases. These are
steadily increasing in Rwanda. The best examples are coronary disease,
cancer, diabetes, obesity and mental illnesses.
Coronary diseases, diabetes, obesity and mental illnesses can be caused
by a combination of genetics and lifestyle. Cancer results from the
malfunctioning of body cells. The substances that cause cancer are called
carcinogens. A carcinogen may be a chemical substance, such as certain
molecules in tobacco smoke. The cause of cancer may be environmental
agents, viral or genetic factors. We should bear in mind, though, that in
the majority of cancer cases we cannot attribute the disease to a single
cause.

• Vocabulary activities:
1. Use the dictionary and thesaurus to look up the missing meanings of
the words/phrases in the table below. Copy the table into your book and
fill in the blank spaces.
2. Write one sentence for each word/phrase to illustrate how they are
used
5.1.2. Application activities:
1. Write a paragraph explaining what transmissible diseases are and
how they can be prevented.
Notes
• A paragraph is normally a body of sentences developing one main
point. Thus, each sentence of the paragraph should explain more on
the main point. They shouldn’t raise a different point.
• Every paragraph should have a topic sentence. A topic sentence
gives the main idea of a paragraph. It usually occurs as the first
sentence of the paragraph.
• Every sentence in a paragraph must be grammatically correct.
• After explanatory sentences which give details about the main topic,
there is always need to have a closing sentence. This should sum up
the topic in the paragraph.
• A good paragraph must focus on the main idea, presented logically
and should have a sense of coherence and completeness.
2. Debate on the following motion:
Schools should conduct mandatory HIV testing on their students.
• Definition of debate
A debate is a structured contest in form of oral arguments about an
issue or a topic. A formal debate involves two teams expressing their
arguments on the topic. Normally, there is a team which proposes or
argues in support of the topic while the second team is on the opposition
side. Each team consists of two or more main speakers
The rules of debate
The debate is always governed by a number of rules as explained below:
• Each team is expected to advance two or three arguments, and two
to three rebuttal speeches. The proposing team gives its argument
first, followed by the rebuttals from the opposing team. There is
always a winding up speech or summarised argument by a selected
member of each team.
The first speaker on each side is supposed to define the key words
or terms of the motion as the basis of advancing his or her points.
• If the opposing side challenges the correctness of a definition
advanced by the proposer, the opposing team provides its view on
the matter.
• Each team of the class debate must advocate or argue in support of
his or her view on the topic.
• In order to establish an assertion, a team must support its arguments
with enough evidence and logic to convince the judges. Facts must
be accurate. Visual materials are permissible to convince the judges.
• In case of a query, the question should be clear and relevant to the
motion of the debate.
• As a matter of procedure, each speaker is expected to respond to
questions as soon as he or she concludes his or her presentation
speech. The speaker concerned may respond to the question
personally, although any other member of his or her team can come
in to assist.
• If anyone, whether in the audience or among the main speakers,
feels unconvinced by a speaker’s argument, he or she is at liberty to
interrupt the speaker by raising a point of information. However,
the chairman of the debate is also at liberty to either permit or
object to the point of interruption.
• The decision about the winning side will be entirely based on the
arguments made and points awarded by a team of juries or judges.

• Important prerequisites and tasks for debate
Team members should:
• Research on the topic and prepare logical arguments.
• Gather supporting evidence and examples to back their arguments.
• Anticipate counter arguments and prepare rebuttals or responses.
• Plan the order of ideas or points with which to argue and support
their points of view.
5.2 Talking about sanitation and related tools
5.2.1 Learning activity: Reading andText analysis
Read the text below and answer the questions that below:
• Text 1: Water and sanitation are human rights.
Sanitation refers to conditions relating to public health, especially the
provision of clean drinking water and adequate sewage disposal. Universal
access to safe water, sanitation and hygiene services are priorities
in Rwanda. Washing hands is critically linked to improved nutrition,
good health, gender equality, economic growth, and environmental
management.
Poor sanitary conditions promote diarrhoea and intestinal parasites
and environmental enteropathy and have complex and reciprocal links
to malnutrition in children. Existing evidence demonstrates that poor
sanitation and hygiene conditions can affect a child’s nutritional status
via at least three direct pathways (i) diarrheal diseases; (ii) intestinal
parasites; and (iii) environmental enteropathy. Malnutrition weakens
the body’s defences and makes children more vulnerable to diseases. At the
same time, diarrhoea and intestinal parasites contribute to malnutrition
by causing decreased food intake, impaired nutrient absorption and
direct nutrient losses
In Rwanda, only 57 per cent of the population access safe drinking water
that is within 30 minutes of their home. When children are forced to
spend time collecting water, it keeps them out of school. This is an issue
especially for girls, who are often expected to take on the majority of
household tasks
Even if water is available near the home, that water is often not safe
to drink. When children drink contaminated water, they risk severe
illness and even death from water borne diseases
Basic sanitation means that every household has its own toilet and does
not share with another household. These toilets should also keep human
waste out of contact with people. Only 64 per cent of the population in
Rwanda have access to these sanitation services.
Just 5 per cent of households in Rwanda have a place for family members
to wash their hands with soap. Hand washing with soap at critical
moments is essential for good health, especially in children.
As a solution UNICEF’s WASH programme in Rwanda aims to ensure
that more households and communities use safe and sustainable water
and sanitation services, and that children and families practice good
hygiene.
UNICEF supports the Government of Rwanda to ensure that every
household: Uses safe and clean water near the home, a hygienic and
private latrine and practices hand washing with soap, especially after
using the toilet and before handling food.

• Comprehension questions
1. How do you think hand washing can be linked to improved
nutrition?
2. Explain the consequences of using dirty water.
3. Which consequences school children who don’t have water near
their homes are likely to face?
4. What does “basic sanitation” mean?
5. What are the critical moments of washing hands?
5.2.2 Application activities:Word and sentence formation
• Vocabulary activities
1. Give the meaning of the following words as used in the above passage.
a. hygiene… (paragraph one)
b. enteropathy…(paragraph two)
c. malnutrition…(paragraph two)
d. nutrient…(paragraph two)
e. contaminated water…(paragraph four)
f. latrine…(paragraph seven)
2. Write one sentence for each of the words to illustrate how they are
use
5.3 Language structure: Conditional
Notes:
Conditionals are sometimes called ‘if clauses’. They describe the result of
something that might happen ‘‘Real situations” (in the present or future)
or might have happened but didn’t ‘‘Unreal situations” (in the past). They
are made using different English verb tenses. There are four main kinds
of conditionals: The Zero, first, second and third conditional.
Nevertheless, not all clauses introduced by “if” can express a condition:
eg:
• Would you mind if I bring you more coffee? (Offer)
• Gatera doesn’t know if Aunt Bintu comes or not. (Wonder),
• The old man wanted to know if people can get diseases from
Umuganura wine.(reported speech)
A. The zero conditional: General truths
The zero conditional is a structure using “if”, but which expresses no
condition at all.
This conditional is used when the result will always happen.
if-clause (present simple), Main clauses (present simple)
Example:
• If you heat water to 100 degrees, it boils.
• If children drink dirty water, they get sick.
• I f you touch fire, you get burned.
• If bacterian get into the body, they cause infection
B. The first conditional: Real/Possible(Present) and its Probable
Condition
(if + present simple, ... will + infinitive)
Example: If you don’t wash your hands properly you will fall sick.
The first conditional is used to talk about things which might happen in
the future. Of course, we can’t know what will happen in the future, but
this describes possible things, which could easily come true.
Here are more examples:
• If it rains, I won’t go to the park.
• If I study today, I’ll go to the party tonight.
• If I have enough money, I’ll buy some new shoes.
• She’ll be late if the train is delayed.
• She’ll miss the bus if she doesn’t leave soon.
• If I see her, I’ll tell her
C. The second conditional: Imaginary/hypothetical condition
and its probable result.
if-clause Main clause
(past simple, ... would + infinitive)
Example: If my hands were clean, I would test this food.
In formal writing ‘were’ is used instead of ‘was’ with ‘I’ and ‘he/she/it’.
The second conditional has two uses:
First, we can use it to talk about things in the future that are probably
not going to be true. If one is imagining some dream for example.
• If I won the lottery, I would buy a big house.(I probably won›t win
the lottery)
• If I met the Queen of England, I would say hello.
• She would travel all over the world if she were rich.
• She would pass the exam if she ever studied.(She never studies, so
this won’t happen)
Second, we can use it to talk about something in the present which is
impossible, because it’s not true. Have a look at the following examples:
• If I had his number, I would call him. (I don›t have his number now,
so it›s impossible for me to call him).
• If I were you, I wouldn’t go out with that man
D.The third conditional: Impossible condition/unreal past
condition and its probable result in the Past
If-clause with the Main clause
(if + past perfect, ... would + have + past participle)
Example:
If they had taken Kalisa to hospital on time,he would not have died.
If-clause Main clause
The third conditional talks about the past. It’s used to describe a situation
that didn’t happen, and to imagine the result of this situation.
• If she had studied, she would have passed the exam, but, we really
know she didn’t study and so she didn’t pass)
• If I hadn’t eaten so much, I wouldn’t have felt sick (but I did eat a
lot, and so I did feel sick).
• If we had taken a taxi, we wouldn’t have missed the plane.
• She would have become a teacher if she had gone to university.
• Note:
Type III inverted form
The Type III If-Clause can also be expressed by Removing ‘If ‘and
inverting the operator (first auxiliary verb) ‘had’ and the subject.
Examples:
If she had studied, she would have passed the exam.
Had she studied; she would have passed the exam.
Some expressions can replace if in the sub-clause, these are for example:
in case, suppose(that), supposing(that), on the condition(that),…
