Match the diseases in Column I with the site of infectious in Column II :
Column I Column II (a) Dengue 1. Intestine, Brain (b) Polio myelitis 2. Skin and Blood (c) Measels 3. Respiratory tract and Nervous system (d) Chicken Pox 4. Skin and Respiratory tract
This question requires matching specific infectious diseases listed in Column I with their corresponding primary sites of infection or major affected systems listed in Column II.
Let's analyze each disease and its typical infectious site:
Dengue is a viral infection transmitted by mosquitoes. The virus primarily targets cells within the blood and immune system. Symptoms often include skin rashes, reflecting involvement of the skin, and systemic effects related to the blood and circulatory system.
Therefore, Dengue matches with: 2. Skin and Blood
Polio myelitis, commonly known as polio, is caused by the poliovirus. The virus typically enters the body through the mouth, infecting the intestine. From the intestine, it can spread to the central nervous system, specifically affecting the nerve cells in the spinal cord and brain, which can lead to paralysis.
Therefore, Polio myelitis matches with: 1. Intestine, Brain
Measles is a highly contagious viral illness. It initially affects the respiratory tract (nose, throat, lungs) causing symptoms like cough and fever. The virus then enters the bloodstream and spreads throughout the body, often causing a characteristic skin rash. In some cases, it can also lead to complications affecting the nervous system.
Therefore, Measles matches with: 3. Respiratory tract and Nervous system
Chicken Pox is caused by the varicella-zoster virus. It is typically acquired through the respiratory tract. After initial infection, the virus spreads through the bloodstream to the skin, where it causes the characteristic itchy, blistering rash. Thus, both the skin and respiratory tract are key sites.
Therefore, Chicken Pox matches with: 4. Skin and Respiratory tract
Here is a summary of the correct matches:
| Column I (Disease) | Column II (Infectious Site) |
|---|---|
| (a) Dengue | 2. Skin and Blood |
| (b) Polio myelitis | 1. Intestine, Brain |
| (c) Measles | 3. Respiratory tract and Nervous system |
| (d) Chicken Pox | 4. Skin and Respiratory tract |
