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?

TMV gives a distinctive 'mosaic' pattern of discolouration on the leaves which affects the growth of the plant due to lack of photosynthesis. 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. What are the symptoms of salmonella and what causes them?

Gonorrhoea is a sexually transmitted disease (STD) with symptoms of a thick yellow or green discharge from the vagina or penis and pain on urinating. What is gonhorrhoea and what are the symptoms?

Gonorrhoea is caused by a bacterium and was easily treated with the antibiotic penicillin until many resistant strains appeared. 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?
