H1N1 virus is sometimes mentioned in the news with reference to which one of the following diseases?
- AIDS
- Bird flu
- Dengue
- Swine flu
Explanation
Option (d) is correct
- Swine flu (H1N1) is a type of influenza infection caused by the H1N1 virus. It is termed “swine flu” because the virus is similar to influenza viruses that commonly affect pigs, where it causes a respiratory (lung) disease. In humans, this virus also leads to a respiratory infection, affecting the lungs and causing flu-like symptoms.
Option (a), (b) and (c) are incorrect
- The H1N1 virus is not associated with AIDS, which is caused by the Human Immunodeficiency Virus (HIV). It is also distinct from bird flu, which is caused by avian influenza viruses like H5N1. Additionally, H1N1 is unrelated to dengue, a Vector-Borne Disease (VBD) caused by the dengue virus.
