What Is Covered in Topic 10 Infectious Diseases?
Topic 10 Infectious Diseases is a core component of the Cambridge International AS & A Level Biology 9700 syllabus. The syllabus specifies that learners must understand the following key areas: 10.1 Infectious diseases and 10.2 Antibiotics.
The infectious diseases studied in this topic are caused by pathogens that are transmitted from one human host to another. Some, like Plasmodium that causes malaria, are transmitted by vectors, but there are many other methods of transmission, such as through water and food or during sexual activity. An understanding of the biology of the pathogen and its mode of transmission is essential if the disease is to be controlled and ultimately prevented. This comprehensive thematic unit plan covers all essential concepts including:
10.1 Infectious Diseases
- Pathogens and Infectious Disease – Understanding that infectious diseases are caused by pathogens (microorganisms that cause disease) and are transmissible between hosts. A pathogen is a microorganism that causes a disease in its host. The four main groups of pathogens are: bacteria (e.g., Vibrio cholerae for cholera, Mycobacterium tuberculosis for TB), viruses (e.g., HIV, measles virus), protoctists (e.g., Plasmodium species for malaria), and fungi (e.g., Trichophyton for athlete’s foot). An infectious disease is one that is caused by a pathogen and can be transmitted from one host to another, either directly (sexual contact, droplets in coughs) or indirectly (water, food, or via a vector such as a mosquito).
- Named Pathogens and Their Diseases – Stating the name and type of pathogen that causes each of the following diseases:
- Cholera – caused by the bacterium Vibrio cholerae
- Malaria – caused by the protoctists Plasmodium falciparum, Plasmodium malariae, Plasmodium ovale and Plasmodium vivax
- Tuberculosis (TB) – caused by the bacteria Mycobacterium tuberculosis and Mycobacterium bovis
- HIV/AIDS – caused by the human immunodeficiency virus (HIV)
- Transmission of Diseases – Explaining how cholera, malaria, TB and HIV are transmitted:
- Cholera – transmitted through ingestion of water or food contaminated with faeces containing V. cholerae. Transmission becomes more likely where sewage contaminates drinking-water supplies, sanitation is limited or hygienic food handling is difficult.
- Malaria – transmitted by a vector. An infected female Anopheles mosquito can transmit Plasmodium when feeding on human blood.
- Tuberculosis (TB) – transmitted mainly in airborne droplets or aerosols released by an infected person, especially during prolonged close contact in poorly ventilated spaces. M. bovis can also infect humans, historically through unpasteurised milk from infected cattle.
- HIV/AIDS – transmitted through sexual contact, blood-to-blood contact, and from mother to child.
- Prevention and Control of Diseases – Discussing the biological, social and economic factors that need to be considered in the prevention and control of cholera, malaria, TB and HIV:
- Cholera control – Safe water treatment, protected water sources, sewage treatment, latrines, handwashing and hygienic food preparation reduce the chance that bacteria move from faeces to a new host. Rapid diagnosis and treatment reduce harm, while surveillance can identify outbreaks and target resources.
- Malaria control – Insecticide-treated bed nets reduce contact between mosquitoes and sleeping people. Indoor residual spraying can kill mosquitoes resting on treated surfaces. Removing or managing standing water can reduce breeding sites. Prompt diagnosis, antimalarial treatment and preventative medicines can reduce illness and the reservoir of transmissible infection.
- TB control – Early case detection, contact tracing, appropriate multidrug treatment, good ventilation, reduction of crowded exposure, vaccination where programmes use it, cattle testing and milk pasteurisation. Completing the prescribed multidrug course is important because MDR-TB (multi-drug resistant tuberculosis) is a global concern.
- HIV/AIDS control – Safe sex practices, screening of blood products, use of sterile needles, antiretroviral therapy (ART) to manage the condition, and education to reduce transmission. HIV targets T helper (CD4+) cells, leading to immune collapse and opportunistic infections.
- Biological, social and economic factors – Biological feasibility is not enough. Infrastructure costs, rapid urban growth, conflict, public trust, access to care and the ability to maintain water systems affect whether a measure succeeds. Control is challenged by insecticide resistance, drug resistance, mosquito behaviour, climate, migration, housing quality, healthcare access and sustained cost.
- Global Patterns of Distribution – Discussing the factors that influence the global pattern of distribution of named infectious diseases. Terms describing spread: Endemic (constantly present in a population), Epidemic (sudden increase above expected baseline), Pandemic (epidemic that has spread across many countries). Cholera is endemic in many developing countries; malaria is endemic in sub-Saharan Africa; TB is a global concern with higher incidence in developing countries; HIV/AIDS has a global distribution with highest prevalence in sub-Saharan Africa.
- Smallpox and Measles – Cambridge expects you to know five named diseases in detail — cholera, malaria, TB, HIV/AIDS and either smallpox or measles. Smallpox is a viral disease that was declared eradicated by the WHO in 1980 (the only human disease to have been eradicated). Measles is a viral disease, prevented by the MMR vaccine, which requires approximately 95% herd immunity for effective control.
10.2 Antibiotics
- Penicillin Action – Outlining how penicillin acts on bacteria and why antibiotics do not affect viruses. Penicillin acts on bacteria by interfering with the synthesis of the bacterial cell wall. Antibiotics do not affect viruses because viruses do not have a cell wall and replicate inside host cells using the host’s cellular machinery.
- Antibiotic Resistance – Discussing the consequences of antibiotic resistance and the steps that can be taken to reduce its impact. The misuse of antibiotics leads to the development of antibiotic resistance in bacterial populations through natural selection – bacteria with resistance mutations survive and reproduce, passing on the resistance genes. Consequences include treatment failure, increased morbidity and mortality, and the emergence of MDR-TB and other drug-resistant pathogens. Strategies to slow its spread include: completing prescribed antibiotic courses, avoiding the use of antibiotics for viral infections, using narrow-spectrum antibiotics where possible, and developing new antibiotics.
