Explanation - Measles is a highly contagious, serious airborne disease caused by a virus. Cause — It is caused by a virus in the paramyxovirus family. Transmission — It spreads by contact with infected nasal or throat secretions (coughing or sneezing) or breathing the air that was breathed by someone with measles. The virus remains active and contagious in the air or on infected surfaces for up to two hours. The virus infects the respiratory tract, then spreads throughout the body, causing severe disease, complications, and even death. Measles Symptoms — The first sign of measles is usually high fever, beginning about 10 to 14 days after exposure to the virus and lasting four to seven days. A runny nose, cough, red and watery eyes, and small white spots inside the cheeks can develop in the initial stage. A rash erupts after several days, usually on the face and upper neck. Who is at Risk of Measles? Any non-immune person (not vaccinated or vaccinated but did not develop immunity) can become infected. Unvaccinated young children and pregnant persons are at the highest risk of severe measles complications. Measles Treatment — No specific antiviral treatment exists for measles. It can be prevented with a safe and effective measles-rubella (MR) vaccine that gives long-term immunity.

Explanation - Obstructive Sleep Apnea (OSA) is the most common sleep-related breathing disorder. People with OSA repeatedly stop and start breathing while they sleep. These breath pauses are known as apneas. There are several types of sleep apnea. OSA occurs when the throat muscles relax and block the airway. This happens off and on many times during sleep. Loud snoring is a telltale symptom of OSA. Anyone at any age can have OSA. But it's most common in middle-aged and older adults. This condition has significant implications for cardiovascular health, mental well-being, quality of life, and driving safety. Treatment for OSA may include — Making lifestyle changes like sleeping position adjustments (not sleeping on your back) or maintaining a weight that's healthy for you. Using a continuous positive airway pressure (CPAP) machine. Wearing oral appliances (mouthpieces). Undergoing surgery.

Explanation - Stagflation is defined as a situation where high inflation and low or negative economic growth (stagnation) occur simultaneously. It is described as "the worst of both worlds" because rising prices typically occur in a booming economy, while high unemployment and low growth typically occur with falling prices (deflation). Combining both is unusual and difficult to resolve with standard policy tools.

Explanation - The Tenth Schedule was inserted in the Constitution in 1985. It lays down the process by which legislators may be disqualified on grounds of defection by the Presiding Officer of a legislature based on a petition by any other member of the House. The law initially stated that the decision of the Presiding Officer is not subject to judicial review. This condition was struck down by the Supreme Court in 1992, thereby allowing appeals against the Presiding Officer's decision in the High Court and Supreme Court. However, it held that there may not be any judicial intervention until the Presiding Officer gives his order.
