What disease do viruses Saturday 4 Ja nuary 2025 cause? 1 Is human skin a specific or non- Non-specific specific defence against pathogens? 2 How do cilia and mucus in the Mucus traps pathogens trachea act as a non-specific barrier Cilia beat and move mucus out to infection? of body transmitted between A disease 3 organisms by a pathogen What is a communicable disease? A microorganism that causes 4 disease What is a pathogen? Lung disease, cardiovascular 5 What three diseases does smoking disease and cancer increase the risk of? CHALLENGE: Compare how the human bodies non-specific barriers to infection prevent infection by pathogens spread by a) food and b) the air. Title:What diseases do viruses causePrior Today Leads to Knowledge Learning Intention: Learning Intention:................... Describe why Explain how measles Recall how communicable viruses are very diseases are spread are HIV are spread hard to destroy and their symptoms using pathogens Measles Key word Measles Measles is a viral Measles is infection that can be considered a fatal. childhood disease Show me…… 1) Measles is caused by a bacteria 2) Measles is caused by a virus 3) Measles is caused by a fungi Activating prior knowledge: Viruses Activation & check of prior knowledge: A few viruses get into the tissue at the back of your throat. A few days later you start to get a cold. Which answer best explains why? 1) The viruses release toxins 2) The viruses eat the cells at the which damage cell making them back of your throat making you ill produce mucus 3) Virus get inside throat cells and 4) Viruses release chemicals reproduces rapidly destroying the which cause a cold cells Activating prior knowledge: Viruses Antibio tics 1. Viruses are 5. Antibiotics ______ 8. Viruses reproduce a) Alive destroy a viral _______ inside the b) Not alive infection body a) Can a) rapidly 2. Viruses are made of b) can not b) slowly a) cells b) not made of cells 6. Antibiotics have 9. Viruses _____ release ______ effect on a toxic chemicals 3. Viruses need viral infection inside the body another cell to a) no a) do a) feed b) a little b) do not b) respire c) a moderate c) reproduce (medium) 10.Viral infections are themselves d) a large ______ to cure using medicines. 4. The cell a virus 7. Antibiotics ________ a) easy infects is usually be used to treat a b) hard a) damaged viral infection b) destroyed a) should always The common cold is caused by a virus and can make us feel really ill. If we have a really bad cold what should we do? 1) Do nothing – the body will get 2) Go to the doctors and ask for better itself antibiotics 3) Take painkillers and go to the 4) Take painkillers and never doctors if the symptoms get really contact the doctors in any bad circumstances Tobacco mosaic virus What diseases do viruses cause? The statements are about bacteria. 1. All bacteria are prokaryotic (have no nucleus) TRU 2. All prokaryotic cells are bacteria E FAL 3. Every prokaryotic organism is made of a single SE TRU cell 4. Bacteria cells can be seen under a very powerful E FAL light microscope 5. All bacteria cause disease SE FAL SE CHALLENGE: Give two differences between a prokaryotic and eukaryotic cell. What diseases do viruses cause? The statements are about viruses. A large number of diseases are caused by viruses. Most viral infections are mild TRU All viral infections are mild and doctors can do E FAL nothing to treat an infected person Antibiotics can be used to treat a viral infection SE FAL Painkillers can treat the causes of a viral infection SE FAL Only animals suffer from viral diseases SE FAL SE CHALLENGE: Explain why any statements you’ve marked as “false” are incorrect Measl 1. Measles is a 5. ______ can prevent 8. Long term measles a) Bacteria suffering from can cause … b) Virus measles a) Fertility problems a) Antiretrovirals b) Increased chance of 2. Measles is a _____ b) Vaccines cancer disease a) non-communicable 6. Antibiotics have 9. Measle infection b) communicable ______ effect on a makes you feel measles infection unwell because … 3. A symptom of a) no a) toxins are released measles is… b) a little b) the virus a) weakened immune c) a moderate reproduces in cells system (medium) causing damage b) low temperature d) a large c) red skin rash 10.Measle infections 7. Vaccines caused a are ______ to cure 4. Symptoms of ____ in measle cases using medicines. measles can be over time. a) easy treated with… a) reduction b) hard 1.

A symptom of HIV is HIV infection because … … a) no a) toxins are released a) weakened immune b) a little b) the virus system c) a moderate reproduces in cells b) fever (medium) causing damage c) red skin rash d) a large 10.The HIV virus is ____ 4. A symptom of AIDS 7. _____ caused a than a body cell. is … reduction in HIV a) larger a) weakened immune cases over time. b) smaller system a) Vaccines c) same size Complete first: Complete once checked blue box Viruses cause a (large / small) number of answers: 1. Why do some viruses cause diseases that affect animals (and / nut not) disease? reproduce inside Viruses plants. Viruses cause disease because they cells then destroy them. reproduce inside cells and then destroy them. Viruses reproduce (rapidly / slowly) 2. Antibiotics Why are virusesdo not hardwork to on inside the human body. Viruses are viruses destroy? (difficult / easy) to destroy as antibiotics Symptoms not causes of (do / do not) work on them. Pain killers can 3. disease What can painkillers treat & not be used to treat the (causes / symptoms) Fever treat? and red rash (can be of diseases. Examples of viral diseases fatal) include: 4. Air What arecoughs – by the symptoms and of Measles measles? sneezes Symptoms: fever and red rash, can be Flu like fatal 5. How is measles spread?AID Virus spread by: air by coughs and sneezes S HIV 6. What contact Sexual are the symptoms of HIV? or exchanging Symptoms: Flu like but can become AIDS bodily fluids CHALLENGE: Explain how measles and attack the body’s immune systemwas almost eliminated 7. What can (gotHIV rid develop off) in the UK and into? whyVirus it has comeby: spread back in the sexual last few contact oryears 8. How is HIV spread? Compare how measles and HIV affect Use humans the following short questions to write an extended answer to the question above. Write your answer in bullet points 1. What type of pathogen causes both diseases? 2. How does this type of pathogen cause disease? 3. Compare how each disease is spread (how is it different 4. Compare the symptoms of each disease 5. What cannot be used to treat either disease (and why) 6. What can be used to treat some of the symptoms of both diseases CHALLENGE: Explain how society has reduced the numbers of people dying from Compare how measles and HIV affect humans. Use the following short questions to write an extended answer to the question above. Write your answer in bullet points Both measles and HIV are caused HIV virus is spread by sexual by viruses (viral pathogens) contact or exchanging bodily fluids Viruses attack cells and reproduce like blood inside them. This destroys the cells Both measles and HIV can be fatal and causes disease Measles symptoms are a high Viruses can reproduce rapidly inside fever and a red rash people HIV symptoms are flu like The measles virus is spread through HIV can develop into AIDS which the air by coughs and sneezes attacks the immune system CHALLENGE: Explain how society has reduced the numbers of people dying from Independent Practice
