Common cold is an acute disease.
Common cold is a viral infection that primarily affects the upper respiratory system. It is a common illness that most people experience multiple times throughout their lives. Here's a detailed explanation of why common cold is considered an acute disease: Definition of acute disease:
An acute disease is a condition that develops rapidly and lasts for a relatively short duration. It is usually self-limiting and resolves within a few days to a few weeks. Reasons why common cold is an acute disease: 1. Sudden onset: Common cold typically starts suddenly, with symptoms appearing within a few days of exposure to the cold virus. The symptoms may include a runny or stuffy nose, sneezing, sore throat, cough, and mild body aches. 2. Short duration: The symptoms of common cold usually resolve within 7-10 days. In some cases, symptoms may persist for up to 2 weeks, but they gradually improve over time. 3. Self-limiting: Common cold is a self-limiting condition, which means it tends to resolve on its own without any specific treatment. Rest, hydration, and symptomatic relief measures are usually sufficient to manage the symptoms. 4. No long-term complications: Unlike chronic diseases, common cold does not cause long-term complications or permanent damage to the body. It is a temporary illness that does not have lasting effects. 5. Highly contagious: Common cold is highly contagious and can spread easily from person to person through respiratory droplets. This contributes to its acute nature, as it can rapidly affect a large number of individuals in a short period. In conclusion, common cold is considered an acute disease due to its sudden onset, short duration, self-limiting nature, lack of long-term complications, and high contagiousness.

Detailed Solution for HOTS Questions: Why do we fall ill? - Question 5
Goitre is caused due to deficiency of Iodine. Explanation: Goitre is a condition characterized by the enlargement of the thyroid gland, which is located in the neck. It can be caused by various factors, but the most common cause is a deficiency of iodine in the diet. Iodine is an essential mineral that is necessary for the production of thyroid hormones. These hormones play a crucial role in regulating the body's metabolism and growth. When there is a deficiency of iodine, the thyroid gland enlarges in an attempt to compensate for the lack of iodine. Here are some key points to understand the relationship between goitre and iodine deficiency: 1. Iodine: Iodine is primarily obtained through the diet, especially from iodized salt, seafood, and certain dairy products. The body needs a small amount of iodine to make thyroid hormones. 2. Thyroid hormones: The thyroid gland uses iodine to produce hormones called thyroxine (T4) and triiodothyronine (T3). These hormones are responsible for regulating the body's metabolism, growth, and development. 3. Iodine deficiency: When there is a lack of iodine in the diet, the thyroid gland cannot produce enough thyroid hormones. As a result, the pituitary gland releases more thyroid-stimulating hormone (TSH) to signal the thyroid gland to produce more hormones. This increased stimulation causes the thyroid gland to enlarge, leading to the formation of a goitre. 4. Goitre symptoms: A goitre can cause a visible swelling in the neck, difficulty swallowing or breathing, hoarseness of voice, and coughing. In severe cases, it can lead to hypothyroidism, a condition characterized by low levels of thyroid hormones. To prevent and treat goitre caused by iodine deficiency, it is important to ensure an adequate intake of iodine through the diet. This can be achieved by consuming iodized salt, seafood, and other iodine-rich foods. In some cases, iodine supplements may be prescribed by a healthcare professional. Overall, goitre is primarily caused by a deficiency of iodine in the diet. Adequate intake of iodine is essential for the proper functioning of the thyroid gland and to prevent the development of goitre.
The interval between infection and appearance of a disease is known as :-
Detailed Solution for HOTS Questions: Why do we fall ill? - Question 6
The interval between infection and appearance of a disease is known as the incubation period. The incubation period is the time it takes for an infection to develop into a clinically detectable disease. During this period, the infectious agent is multiplying within the body, but the person does not yet exhibit any signs or symptoms of the disease. The length of the incubation period can vary depending on the specific infectious agent and the individual's immune response. Key points: - The incubation period is a crucial phase in the progression of a disease. - It begins with the initial infection and ends when the first symptoms appear. - The duration of the incubation period can vary from hours to years, depending on the specific disease. - Factors that can influence the length of the incubation period include the infectious agent's characteristics, the route of transmission, the individual's immune system, and other host factors. - During the incubation period, individuals may unknowingly transmit the infection to others, as they may not display any symptoms. - Monitoring the incubation period is essential for disease control and prevention strategies, as it helps identify and isolate infected individuals before they become symptomatic and can spread the disease to others. In conclusion, the incubation period is the interval between infection and the appearance of disease symptoms. It is an important concept in understanding the progression and transmission of infectious diseases.

Detailed Solution for HOTS Questions: Why do we fall ill? - Question 10
AIDS stands for acquired immunodeficiency syndrome, a disease that makes it hard for the body to fight off infectious diseases. HIV, the virus which causes AIDS, can be spread through unprotected sexual intercourse (can still be spread using a condom, but it’s a lot rarer), blood transfusion with HIV infected blood, and breast milk.
The most common cause of non-sexual HIV transmission is mother-to-child. If a woman infected with HIV or AIDS has a baby, there’s a chance the baby will be infected in the womb, or become infected after birth through the breast milk. This is why it is not recommended that HIV-positive women breastfeed, and a lot of developing countries have education and support groups for new mothers warning of this.

Detailed Solution for HOTS Questions: Why do we fall ill? - Question 17
House flies are the vectors of Cholera. House flies, scientifically known as Musca domestica, are commonly found in and around human settlements. These insects are known for their ability to transmit various disease-causing pathogens, making them dangerous vectors. One such disease that house flies are known to transmit is Cholera, caused by the bacterium Vibrio cholerae. Here's how house flies can become carriers of cholera: 1. Feeding habits: House flies have a liquid diet and are attracted to various food sources, including human or animal feces. Cholera bacteria can be present in contaminated water or food, especially if it has been contaminated with fecal matter containing the bacteria. 2. Contamination: When house flies feed on fecal matter or other contaminated substances, they can pick up cholera bacteria on their legs and mouthparts. These bacteria can then be transferred to other surfaces, including human food, utensils, and even human skin. 3. Transmission: House flies have a habit of regurgitating and defecating while feeding. This behavior can lead to the direct transfer of cholera bacteria from the fly to a human or another surface. If contaminated food or water is ingested by a person, they can become infected with cholera. 4. Poor sanitation: House flies thrive in unsanitary conditions where there is poor sanitation and a lack of proper waste management. These conditions increase the likelihood of exposure to cholera bacteria and the transmission of the disease. It is important to note that while house flies can carry cholera bacteria, they are not the sole cause of the disease. Cholera is primarily transmitted through the consumption of contaminated water or food. However, house flies can contribute to the spread of the disease, especially in areas with inadequate sanitation and hygiene practices. In conclusion, house flies can act as vectors for cholera by picking up the bacteria from contaminated sources and transferring them to human food and surfaces. Preventing fly infestations and maintaining proper sanitation and hygiene practices are crucial in reducing the risk of cholera transmission.
