H1N1 virus is sometimes mentioned in the news with reference to which one of the following diseases?

Defines AIDS as a disease caused by the human immunodeficiency virus (HIV), linking a specific disease to a specific viral agent.

A student can extend this by checking whether H1N1 is named or classified as HIV or a different virus to see if it matches the causative agent.

Explains HIV transmission, targets (helper T cells), and that AIDS is the final stage of HIV infection—showing disease specificity and distinct pathology.

Compare the known targets and transmission modes of H1N1 (respiratory spread, different tissue targets) to those of HIV to judge if H1N1 could cause the same syndrome.

Lists influenza (a virus) and its site of infection (respiratory tract) and symptoms, treating influenza and AIDS as separate entries in disease tables.

Use this pattern to check whether H1N1 appears under influenza/respiratory diseases rather than under AIDS/HIV in standard disease classifications.

Presents epidemics and explicitly lists both swine flu and AIDS separately among major diseases, implying they are distinct conditions.

A student can use this separation as a basis to verify that swine flu (H1N1) and AIDS are treated as different epidemics caused by different agents.

States that viruses infect different hosts and cause specific diseases when they enter particular cells, indicating that 'a virus' is not a single interchangeable cause for all viral diseases.

Extend by noting that because different viruses infect different cells and cause different diseases, one should check whether H1N1 infects the cells implicated in AIDS (helper T cells) — if not, it likely does not cause AIDS.

Says 'bird flu shut down supplies of poultry exports', linking 'bird flu' specifically to birds/poultry as the affected host group.

A student could use this host-pattern to check whether H1N1 is primarily associated with birds/poultry or with a different animal/human host.

Mentions a 'swine flu outbreak' (separately from bird flu), indicating different flu outbreaks are named after their typical animal hosts.

A student could use the naming pattern (swine, bird) to ask whether H1N1 is the strain commonly called swine flu or bird flu and thus infer if it causes bird flu.

Defines viruses as agents that may infect plants, animals or bacterial cells and may cause disease — establishes that different viruses infect different host types.

A student could apply this rule to examine which host species H1N1 infects (human, swine, avian) to judge if it causes bird flu.

Lists influenza among common communicable diseases and identifies 'virus' as the causal agent, linking 'flu' as a disease category caused by various viral strains.

A student could check which viral subtype (e.g., H1N1 vs H5N1) corresponds to which 'flu' name (human/swine/bird) to see if H1N1 aligns with bird flu.

Groups bird flu together with other named epidemics (HIV, SARS) as distinct disease events that spread across countries, implying specific named diseases are distinct entities.

A student could treat 'bird flu' as a distinct named epidemic and look up whether H1N1 is listed among those specific bird flu epidemics or is a different influenza event.

States that dengue is caused by the dengue virus and is carried/transmitted by Aedes mosquitoes (vector-borne).

A student can combine this with the basic fact that H1N1 is an influenza virus (not mosquito-borne) to see whether one virus could be the vector for the other.

Lists dengue fever explicitly as a disease caused by a virus and highlights its transmission via insect vectors.

Use the rule 'dengue = mosquito-transmitted virus' and compare transmission modes of H1N1 to judge causality.

Describes influenza as a viral disease that spreads through the air and infects the respiratory tract.

Combine this airborne-transmission pattern for flu with the mosquito-borne pattern for dengue to infer incompatibility of causation by one virus causing the other.

Groups dengue and flu as distinct communicable diseases caused by pathogens, implying different disease identities.

A student could use this classification to treat dengue and influenza (H1N1) as separate disease entities to be compared for cause-effect relationships.

Lists 'swine flue' (influenza) and dengue separately among major epidemics, suggesting they are distinct epidemic diseases.

Seeing them catalogued separately supports checking whether the agent of one (swine flu/H1N1) is known to produce the other's syndrome (dengue) via their different epidemiologies.

This snippet explicitly mentions a 'swine flu' outbreak, establishing that 'swine flu' is a named illness/events recorded in these texts.

A student could treat 'swine flu' as a specific flu disease to be checked against known influenza subtypes (e.g., by consulting standard disease lists or public-health sources).

Table entry lists 'influenza' (flu) under diseases caused by viruses and affecting the respiratory tract—showing the general rule that 'flu' illnesses are viral.

Use the rule 'flu = viral disease' to infer that any named flu (including 'swine flu') is likely viral and thus could be caused by a particular virus subtype like H1N1; verify by looking up which influenza virus subtypes are associated with 'swine flu'.

Defines viruses as microscopic agents that infect animals and may cause disease, giving the generic mechanism by which an agent like H1N1 could cause illness.

Combine this with the identification of 'flu' as viral to reason that a named virus (H1N1) plausibly could be the causal agent for a flu called 'swine flu'; confirm by checking virology nomenclature for H1N1.

Explains antibiotics do not work against viruses, reinforcing that knowing a disease is viral has practical implications and supports distinguishing viral flu from bacterial illnesses.

A student could use treatment differences (antibiotics ineffective) as a cross-check: if swine flu is managed as a viral influenza in public-health guidance, that supports it being caused by a virus such as an influenza subtype.

Groups 'Cold and flu' among communicable diseases (implying contagious viral respiratory illnesses), supporting that flu-type diseases are a communicable viral category.

Use this categorization to narrow searches to communicable/viral influenza variants and then look up which named viral strains (e.g., H1N1) are reported as causing 'swine flu'.
