by ads Converclick on July 08, 2024

Keeping students and school staff safe and healthy is a top priority in any educational institution. Preventing illness in schools requires the collaboration of parents, teachers, and administrators to implement effective hygiene and health practices. Here are practical tips based on research and studies on the effectiveness of these preventive measures.

Proper Use of Masks

Importance: The proper use of masks has been shown to be one of the most effective tools for reducing the transmission of respiratory diseases, including COVID-19. According to the Centers for Disease Control and Prevention (CDC), masks can significantly reduce the spread of respiratory droplets that contain viruses and bacteria.

Practical Tips:

  1. Mask Selection: Choose masks with at least three layers, preferably made of non-woven material for better filtration.
  2. Proper Fit: Ensure masks fully cover both the nose and mouth, without gaps at the sides.
  3. Regular Replacement: Disposable masks should be changed after each use, and reusable masks should be washed daily.

Statistics and Studies:

  • A study published in Health Affairs found that mask mandates in public were associated with a 2% decrease in the daily growth rate of COVID-19 infections​.
  • The World Health Organization (WHO) notes that masks are an effective barrier to reduce respiratory disease transmission​​.

Importance of Hand Washing

Importance: Hand washing is one of the simplest and most effective ways to prevent the spread of diseases. The CDC estimates that hand washing can reduce respiratory illnesses in the general population by about 16-21%.

Practical Tips:

  1. Correct Technique: Wash hands with soap and water for at least 20 seconds. Ensure to scrub all surfaces, including wrists, between fingers, and under nails.
  2. Key Moments: Wash hands before and after eating, after using the restroom, after touching common surfaces, and after coughing or sneezing.
  3. Use of Sanitizers: When soap and water are not available, use a hand sanitizer with at least 60% alcohol.

Statistics and Studies:

  • Research published in the Journal of School Health shows that hand hygiene education programs in schools can reduce absenteeism due to gastrointestinal illnesses by about 29%​​.
  • A study in the American Journal of Infection Control found that regular use of hand sanitizers in schools reduces respiratory infections by 20%​​.

Use of Disinfectants

Importance: Disinfectants are crucial for keeping surfaces free of pathogens. Viruses and bacteria can survive on surfaces for hours or even days, making regular disinfection essential.

Practical Tips:

  1. Effective Products: Use EPA-approved disinfectants that are effective against a broad spectrum of pathogens, including coronaviruses.
  2. Frequency of Disinfection: Disinfect high-touch surfaces multiple times a day, including doorknobs, desks, keyboards, and bathrooms.
  3. Usage Instructions: Follow the manufacturer’s instructions to ensure proper contact time and effective disinfection.

Statistics and Studies:

  • According to the CDC, cleaning and disinfecting high-touch surfaces can significantly reduce the spread of diseases​​.
  • A study in the Journal of Hospital Infection demonstrated that disinfectants with at least 70% alcohol are highly effective at inactivating the SARS-CoV-2 virus on surfaces in less than 30 seconds​​.

Implementation of Additional Measures

Adequate Ventilation: Maintaining good ventilation in classrooms helps reduce the concentration of viruses in the air. Whenever possible, open windows and doors to increase natural airflow. HEPA filter air purification systems can also be beneficial for improving indoor air quality.

Education and Awareness: Educating students and staff about the importance of these measures is key to their effective implementation. Conduct workshops and informational sessions on the proper use of masks, correct hand washing techniques, and the importance of regular disinfection.

School Health Policies: Establish clear policies on staying home when sick, using personal protective equipment, and responding to disease outbreaks in the school. Ensure that all members of the school community are informed and committed to these policies.


Preventing illness in schools is a task that requires the combined effort of parents, teachers, and administrators. By using masks properly, washing hands regularly, and disinfecting surfaces, we can create a safer and healthier school environment. Implementing these measures based on studies and statistics not only protects the health of students and staff but also contributes to continuous and uninterrupted education.
