Match List-I with List-II.
| List-I (Disease) | List-II (Feature) |
| A. Typhoid | I. Infects the nose and respiratory passage but not the lungs |
| B. Pneumonia | II. Sustained high fever |
| C. Common cold | III. Chronic inflammation of the lymphatic vessels of the lower limbs |
| D. Filariasis | IV. Alveoli get filled with fluid |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → A-II, B-IV, C-I, D-III
(A) Typhoid — this matches (II) Sustained high fever. Salmonella typhi enters through contaminated food and water. The main symptom is a sustained high fever of 39° to 40°C, with weakness, stomach pain and loss of appetite.
(B) Pneumonia — this matches (IV) Alveoli get filled with fluid. Streptococcus pneumoniae and Haemophilus influenzae infect the alveoli of the lungs. The fluid in the alveoli causes severe problems in respiration.
(C) Common cold — this matches (I) Infects the nose and respiratory passage but not the lungs. Rhino viruses cause the common cold. The lungs are not affected, which sets it apart from pneumonia.
(D) Filariasis — this matches (III) Chronic inflammation of the lymphatic vessels of the lower limbs. The filarial worms, Wuchereria, live in these vessels for many years, and the disease is also called elephantiasis.
NCERT Extract:
Common Diseases in Humans – “… Salmonella typhi is a pathogenic bacterium which causes typhoid fever in human beings. … Sustained high fever (39° to 40°C), weakness, stomach pain, constipation, headache and loss of appetite are some of the common symptoms of this disease. … As a result of the infection, the alveoli get filled with fluid leading to severe problems in respiration. … Rhino viruses represent one such group of viruses which cause one of the most infectious human ailments – the common cold. They infect the nose and respiratory passage but not the lungs. … Wuchereria (W. bancrofti and W. malayi), the filarial worms cause a slowly developing chronic inflammation of the organs in which they live for many years, usually the lymphatic vessels of the lower limbs and the disease is called elephantiasis or filariasis (Figure 7.2).”
