Measles is a viral disease showing symptoms of fever and a red skin rash. Measles is a serious illness that can be fatal if complications arise. For this reason most young children are vaccinated against measles. |
|
What is measles and why are young children vaccinated against it? |
|
|
|
The measles virus is spread by inhalation of droplets from sneezes and coughs. |
|
How is the measles virus spread? Show an image of a student with measles and ask students to consider how it is transmitted. |

|
HIV initially causes a flu-like illness. Unless successfully controlled with antiretroviral drugs the virus attacks the body's immune cells. |
|
What is the initial symptom of HIV and what do antiretroviral drugs stop the virus doing? Split students into teams and allocate them a virus disease to research and either create a presentation or a poster to display for a market place fact collecting activity. Their presentations should include:
1. How the disease is transmitted
2. The effects of the disease
3. How the spread of the disease can be prevented |
|
|
|
Late stage HIV infection, or AIDS, occurs when the body's immune system becomes so badly damaged it can no longer deal with other infections or cancers. |
|
When does late stage HIV infection or AIDS occur? GF: Why will HIV never be truly eradicated? |
|
|
|
HIV is spread by sexual contact or exchange of body fluids such as blood which occurs when drug users share needles. |
|
How is HIV spread? |

Tobacco mosaic virus (TMV) is a widespread plant pathogen affecting many species of plants including tomatoes. |
|
What is tobacco mosaic virus? |
|

|
How does tobacco mosaic virus reduce growth in plants? |
|

|
Salmonella food poisoning is spread by bacteria ingested in food, or on food prepared in unhygienic conditions. |
|
How is Salmonella food poisoning spread? |
|
|
|
In the UK, poultry are vaccinated against Salmonella to control the spread. |
|
What animal is vaccinated in the UK to control the spread of Salmonella? |
|
|
|
Fever, abdominal cramps, vomiting and diarrhoea are caused by the [Salmonella] bacteria and the toxins they secrete. |

|
How and why has treatment of gonorrhoea changed over time? |
|
|
|
Gonorrhoea is spread by sexual contact. |
|
How is gonhorroea spread? |
|
|
|
The spread can be controlled by treatment with antibiotics or the use of a barrier method of contraception such as a condom. |
|
How can the spread of gonorrhoea be controlled? |
