Test: Hygiene - Class 9 MCQ

Avoiding sharing towels is important to prevent eye infections, as towels can harbor germs that may be transferred to the eyes. Maintaining personal hygiene items helps reduce the risk of infections.

Personal hygiene plays a crucial role in health by helping to prevent the spread of diseases. Good hygiene practices, such as handwashing and bathing, reduce the likelihood of infections and contribute to overall well-being.

The Anopheles mosquito is the primary vector for malaria, caused by the Plasmodium protozoan. Understanding the role of this mosquito is critical for developing prevention strategies, such as using insect repellent and mosquito nets.

Houseflies are known to spread cholera, a severe waterborne disease caused by the bacterium Vibrio cholerae. They can contaminate food and surfaces with pathogens they carry on their bodies, contributing to outbreaks in unsanitary conditions.

Severe diarrhea is a hallmark symptom of cholera, leading to rapid dehydration and potential fatality if untreated. It is critical to seek medical attention and ensure access to clean water to prevent cholera outbreaks.

Boiling water before use is the primary method to prevent water contamination. This practice kills harmful pathogens, ensuring the water is safe for drinking and reducing the risk of waterborne diseases.

The Culex mosquito is known to spread filariasis, a disease caused by parasitic worms. Awareness of this vector and implementing control measures can significantly reduce the incidence of this disease.

Covering food items is essential to prevent contamination by houseflies. Flies can transfer germs from unsanitary surfaces to food, so keeping it covered minimizes the risk of foodborne illnesses.

Cholera is a common waterborne disease caused by the Vibrio cholerae bacterium. It spreads primarily through contaminated water and can lead to severe dehydration, making prevention and sanitation crucial.

Keeping public places clean is a vital aspect of social hygiene. It helps prevent the spread of diseases in communal areas, such as schools and restaurants. Clean environments reduce the risk of infections and promote overall public health.

Washing eyes with clean water 2-3 times daily can help prevent infections like trachoma and conjunctivitis. Good eye hygiene is essential to remove irritants and reduce the risk of infection, especially in communal settings.

Inadequate sanitation in public places leads to the spread of diseases, as unsanitary conditions can harbor pathogens that affect community health. Ensuring cleanliness in communal areas is essential to prevent outbreaks and protect public health.

The life cycle of a housefly consists of four stages: egg, larva, pupa, and adult. Understanding this cycle helps in implementing effective control measures to reduce fly populations in various environments.

Adults generally need 6-7 hours of uninterrupted sleep for optimal health. Sufficient sleep is crucial for the proper functioning of all body organs, including the brain, as it allows for recovery and restoration during rest periods.

Teeth should be brushed twice a day—once in the morning and once at night. This practice helps prevent tooth decay and gum infections, ensuring good oral health. Regular brushing removes plaque and food particles that can lead to cavities.

Smoking tobacco is not a healthy habit; it can lead to numerous health issues, including cancer and respiratory diseases. Maintaining healthy habits like regular meals and sleep schedules is crucial for overall well-being.

Filling up small ponds and puddles eliminates potential mosquito breeding sites, reducing their populations. This proactive approach is vital in preventing diseases like malaria and dengue, which are transmitted by mosquitoes.

Regularly removing household refuse and waste is effective in controlling housefly breeding. By eliminating potential breeding sites, such as leftover food and garbage, one can significantly reduce fly populations and the diseases they spread.

Daily bathing is essential for personal hygiene as it helps remove germs and body odor, keeping the skin clean and sweat pores open. Regular bathing not only promotes cleanliness but also contributes to overall health by reducing the risk of infections.

Yellowish eyes, known as jaundice, is a common symptom of hepatitis A, which is a waterborne viral infection. Recognizing symptoms early can lead to prompt medical attention and better health outcomes.
