1.
When is Global Handwashing Day observed worldwide?
Correct Answer
A. October 15
Explanation
Global Handwashing Day is observed on October 15 each year to promote awareness of the importance of hand hygiene. It was established in 2008 by the Global Handwashing Partnership to encourage individuals and communities to adopt regular handwashing practices. The date was chosen to align with ongoing health campaigns and ensure maximum impact. Since its inception, it has been widely celebrated worldwide through educational programs, public health initiatives, and school activities. The observance of this day has significantly contributed to reducing the spread of infectious diseases, particularly in developing regions where hygiene-related illnesses are prevalent.
2.
What is the main purpose of Global Handwashing Day?
Correct Answer
A. To promote proper hand hygiene
Explanation
The primary purpose of Global Handwashing Day is to promote proper hand hygiene and emphasize its role in preventing infections. Studies show that handwashing with soap reduces the risk of diarrhea by nearly 50% and respiratory infections by 20%. These diseases are among the leading causes of child mortality worldwide. The campaign aims to instill the habit of washing hands at critical times, such as before eating and after using the restroom. Effective hand hygiene also helps combat outbreaks of diseases like cholera and COVID-19, highlighting its necessity for global health and safety.
3.
What is the minimum recommended time to wash hands with soap?
Correct Answer
C. 20 seconds
Explanation
The minimum recommended time for washing hands with soap is 20 seconds, according to health organizations like the CDC and WHO. Research indicates that washing for less time does not effectively remove all bacteria and viruses. A 20-second wash ensures enough time for the soap to break down grease and dirt while allowing water to rinse off harmful microorganisms. This recommendation is supported by scientific studies demonstrating that shorter washes leave behind significant contamination. Proper handwashing for at least 20 seconds can reduce the risk of illness, particularly in high-contact environments like schools and hospitals.
4.
What is the most effective way to remove germs from hands?
Correct Answer
C. Washing with soap and water
Explanation
The most effective way to remove germs from hands is by washing with soap and water. Soap molecules break down oils and grease that trap germs, allowing water to wash them away. Studies reveal that soap and water remove more bacteria than hand sanitizers alone, particularly against norovirus and Clostridium difficile. While hand sanitizers are useful in some situations, they do not eliminate all types of germs. Washing with soap is especially crucial after handling raw food, using the toilet, or coughing, as it significantly reduces the risk of bacterial and viral transmission.
5.
Which critical moments require handwashing according to WHO?
Correct Answer
A. Before eating and after using the toilet
Explanation
Handwashing at critical moments—such as before eating and after using the toilet—is essential for preventing illness. The World Health Organization emphasizes these moments because they involve high exposure to harmful pathogens. Studies show that unwashed hands after using the toilet can spread fecal bacteria, which may cause diseases like diarrhea and hepatitis A. Similarly, washing hands before eating prevents the ingestion of germs that can lead to foodborne illnesses. Public health campaigns focus on these key moments to minimize disease transmission in households, schools, and workplaces, especially in areas with limited access to clean water and sanitation.
6.
What type of disease can be prevented through proper handwashing?
Correct Answer
B. Respiratory infections
Explanation
Proper handwashing prevents respiratory infections such as colds, flu, and pneumonia. These infections spread through droplets when people cough, sneeze, or touch contaminated surfaces. Research shows that frequent handwashing reduces respiratory illnesses by up to 20%. This is particularly important in hospitals and crowded places where airborne viruses are common. During outbreaks like COVID-19, hand hygiene played a critical role in reducing transmission rates. Health authorities worldwide recommend handwashing as a primary defense against respiratory diseases, demonstrating its effectiveness in minimizing infections and protecting public health on a large scale.
7.
Why is soap essential in handwashing?
Correct Answer
A. It kills germs effectively
Explanation
Soap is essential in handwashing because it effectively removes germs by breaking down oils and fats that trap bacteria. Scientific studies prove that soap reduces the presence of harmful microbes significantly more than rinsing with water alone. Soap contains molecules that attach to both water and grease, allowing dirt and germs to be rinsed away. Without soap, many pathogens remain on the skin even after scrubbing. The use of soap in developing countries has been linked to lower rates of diarrhea and respiratory infections, making it a critical component in global health initiatives focused on hygiene improvement.
8.
What is the best temperature for handwashing water?
Correct Answer
D. It does not matter
Explanation
The temperature of handwashing water does not significantly affect germ removal, as research indicates that both cold and warm water are equally effective when combined with soap. A study by Rutgers University found that water temperature did not impact the reduction of bacteria when hands were washed properly for 20 seconds. Boiling water can cause burns, while cold water may be uncomfortable, discouraging people from washing their hands long enough. The key factor is thorough scrubbing with soap rather than temperature, ensuring that germs and contaminants are effectively removed from the skin.
9.
What percentage of infectious diseases can be prevented by proper handwashing?
Correct Answer
C. 50%
Explanation
Studies estimate that proper handwashing can prevent up to 50% of infections caused by bacteria and viruses. Research by the CDC and WHO shows that handwashing significantly reduces the spread of diarrheal diseases, which kill thousands of children annually. Additionally, studies on respiratory infections confirm that regular handwashing lowers transmission rates. In hospitals, strict hand hygiene protocols prevent infections among patients and healthcare workers. Since many illnesses spread through hand contact, promoting handwashing as a routine habit can substantially reduce the global burden of infectious diseases, particularly in regions with inadequate sanitation and healthcare facilities.
10.
Who initiated Global Handwashing Day in 2008?
Correct Answer
C. Global Handwashing Partnership
Explanation
Global Handwashing Day was initiated in 2008 by the Global Handwashing Partnership, an organization focused on improving hygiene worldwide. The campaign was launched in response to the growing recognition of handwashing as a key public health measure. Since its establishment, this annual event has been celebrated in over 100 countries, involving governments, schools, and health organizations. Educational programs, media campaigns, and community events help raise awareness about the importance of hand hygiene. The initiative has contributed to a significant increase in handwashing practices, reducing illness rates and promoting better health, particularly in developing countries with limited access to clean water.
