We fall ill because pathogen go in to your body harm us. They go into our body from cuts, eyes, nose, mouth, skin etc. These pathogen harm us by reproducing them. For virus, they go into our cell and reproduce theirselves or DNA and destroy more cells in our body by bursting out from their host cell or make the body weak from other pathogens. For bacteria, they reproduce theirselves and make the toxins which can harm us.

We fall ill due to pathogens such as bacteria, viruses and fungi or parasites. These pathogens can enter our body through the air which we breathe, the food and drinks which we consume or even through openings within our skin, such as cuts. And through this the harmful pathogens; along with the good, enter our body's cells causing us to fall ill.

# data[].attributes.body
We fall ill when our body fail to protect us from harmful pathogens (bacteria, fungi, viruses and parasites) that enter our body. They enter through holes in our body like our eyes and nose.

# data[].attributes.body
Pathogens, or microbes enter are body through our nose, mouth, injuries, wounds,  etc and enter our body and multiply, causing more damage to the normal functioning of our body. That is why we have a immune system to try to stop these invading pathogens from causing disease and most of the time, the diseases d not even get past the outer layer like our face or our skin. If they get through the skin, then the immune system begins the immune response, which has 3 phases. At first, the memory cells try to recognise them to see if they can recognise it. If they can, they destroy it.

We fall ill when a pathogen (virus, bacteria fungi) enters our bloodstream. The pathogen then multiplies in our bloodstream. Disease occurs when cells in your body are damaged due to infection and signs or symptoms begin to appear.

We fall ill because of the pathogens that are around us. pathogens such as bacteria, viruses, fungi and parasites cause both infectious and non-infectious diseases. These pathogens can enter the body through the air we breathe, the food and drink we consume or through openings in the skin, such as cuts. A person who has cold can pass their virus through another person through contact

microbial (bacterial, viral) infections, parasitic infections, ingestion of toxic substances (such as toxic mushrooms, deteriorating foods) or harmful chemicals, harsh environmental conditions (such as colds, heat stroke),etc.

We fall ill from infectious diseases by pathogens such as bacteria, fungi and viruses. The pathogens enter our body through open holes such as, the nose, mouth, ears, eyes, wounds and genitals. This infection infects us and we never realise it, until we fall ill. This is because they need time to multiply themselves to cause problems. We make toxins as they start to multiply. These are chemicals that are harmful to other organisms and for us, which can make us ill.

1) Our body’s well-being is dependent on the proper functioning of its cells and tissues.
2) All our body parts and activities are greatly interconnected. Hence dysfunction of any body part
will affect the entire body.
3) When we are healthy, we are able to perform our physical, mental and social functions well.
4) Our physical and social environment plays an important role in maintaining good health.
5) In addition to personal hygiene, public cleanliness should also be maintained for ensuring that
we remain healthy.
6) Many other factors like financial conditions, availability of nutritious food and social equality also
influence the health of an individual.
7) A person suffering from a disease is in a state of discomfort.
8) Being in poor health is different from being diseased.
9) Symptoms and signs of the disease appear as a result of dysfunction of the affected body parts.
These help to identify the disease that a person is suffering from.
10) Depending on their duration, diseases may be classified as acute or chronic.
11) Acute diseases last for a short time and do not cause major health effects. E.g. Common cold.
On the other hand chronic diseases persist for a long time and hence cause prolonged ill health.
E.g. TB of lungs.
12) Causes of diseases may be immediate (first level cause) or contributory. For e.g. – The immediate
cause of a person suffering from diarrhoea is the causative agent. The contributory causes could
be i) lack of good nourishment or genetic difference (second level cause), ii)
poverty or lack of public services (third level cause)
13) Diseases may be infectious or non-infectious. Infectious diseases are caused by microbes or
other infectious agents (e.g. Malaria) whereas non-infectious diseases have internal, noninfectious causes (e.g. High blood pressure).
14) The infectious agents may be viruses, bacteria, fungi, protozoans or multicellular organisms like
worms.
15) The type of treatment of a disease depends on the category of the infectious agent.
16) Organisms belonging to one category will share several important life processes, which will be
different from those of organisms belonging to other categories.
17) Drugs working by interfering with life processes of one category of organisms will not be
effective against members of another category. E.g. Antibiotics act against bacteria, but not
viruses, since viruses do not share bacterial pathways.
18) Penicillin interferes with bacterial cell wall production, thus killing the bacteria. Due to lack of
cell walls, penicillin does not affect human cells.
19) Many infectious diseases are called ‘communicable diseases’ since they can spread from one
person to another.
20) Communicable diseases can spread through air, water, food, sexual contact or vectors.
21) The droplets released during coughing or sneezing of an infected person causes the spread of
air-borne diseases like common cold, pneumonia, tuberculosis etc.
22) Air-borne diseases spread quickly in overcrowded and poorly ventilated living conditions.
23) Water-borne diseases like cholera spread when drinking water gets contaminated with the
infectious agents.

24) Sexual contact causes the spread of diseases like AIDS and syphilis from the infected person to ahealthy one. AIDS virus can also spread through blood transfusions, use of infected needles or
during pregnancy and breast-feeding by an infected mother.

25) Vectors are intermediate animals causing the spread of disease causing agents from an infected
person to a healthy person. For example – Female mosquitoes transmit many diseases like
malaria when they feed on the blood of animals and humans.
26) On entering the body, the infectious agents reach their specific target organs. In certain cases the
target organ is related to their point of entry. For e.g. – Typhoid causing bacteria enter through
mouth and reside in gut lining.
27) In other instances, the target organ of the microbe has no relation to their point of entry. For e.g.
HIV enters through the sexual organs but spreads to all the lymph nodes.
28) The symptoms of a disease depend on the target organ infected by the microbe. For e.g. cough
and breathing problems are seen when lungs are infected. So based on the signs and symptoms
of a disease, we can get an idea of the target organ of the microbe.
29) During infection, the body’s activated immune system sends specialized cells to destroy the
microbes, causing inflammation, with associated local effects.
30) The AIDS causing virus destroys the functioning of the immune system, due to which the body
becomes unable to fight even minor infections. Ultimately the patient succumbs to such
infections.
31) The severity of a disease is directly proportional to the number of infectious agents present in
body.
32) An infectious disease can be treated in 2 ways:
i) Reduce the symptoms of the disease by providing treatment ii) Kill the infectious
agent causing the disease.
33) Medicines used in killing an infectious agent aim to disrupt some pathway of a vital life function
peculiar to that group of organisms. These pathways are not present in other microbial groups or
in humans.
34) On entering human cells, viruses use our cellular machinery for carrying out all their life
processes. There are very few virus-specific biochemical pathways that can be targeted to
produce anti-viral drugs.

by pathogens entering our bloodstream, reproducing and releasing toxins. These pathogens are bacteria, viruses, fungi and parasites. These pathogens can enter our bloodstream by: inhaling them, entering through eyes/nose/ears and genitals. Evidence of the immune system responding to the infection is swelling(around the infected area) and fever.

We get ill because of pathogens infecting our bodies. When pathogens (bacteria, viruses and fungi) infect our bodies, they multiply and cause toxins (bacteria) destroy and harm cells (viruses) which make us sick. Our immune system combats pathogens to help us get better.
