Crowd Health
(Public Health)
This topic will help you learn about crowd health.
What is crowd health?
Crowd health is a branch of public health that aims to ensure health safety and prevent diseases during large human gatherings that may exceed the capacity of the local health system. Hajj is a prominent example of this type of event, where millions of people from different countries participate, which requires precise and exceptional planning to prevent the spread of diseases, secure medical services, and efficiently manage health emergencies.
What is the importance of crowd management?
- Crowd health is a fundamental element in crowded places and seasons that witness large inflows of people, such as the Hajj season. Given the tremendous density during this blessed season, crowd management becomes an urgent necessity to ensure pilgrims’ safety and preserve their health.
- Health management of crowds also plays a pivotal role in:
- Reducing the spread of infectious diseases by decreasing opportunities for infection in crowded places.
- Facilitating access to healthcare by distributing mobile ambulance centers and medical services at strategic points.
- Rapid response to emergencies such as heat stress, fainting, or injuries resulting from crowding.
Promoting health awareness through campaigns about personal hygiene, drinking water, prevention of sunstroke, and others.
Organizing movement to reduce bottlenecks and prevent accidents caused by congestion or stampedes.
All these efforts contribute to building an integrated and robust health system capable of absorbing and dealing with the exceptional nature of the Hajj season, which enhances pilgrims’ safety, reassures them, and enables them to perform their rituals with spirituality and peace.
What are the essential aspects of crowd health during the Hajj season?
Crowd health is an integrated system aimed at maintaining individuals’ safety during major human gatherings, such as Hajj, and relies on several main pillars that work together to ensure a safe health environment. According to the World Health Organization, dealing with such gatherings requires focusing on several pillars due to the unique health challenges they impose.
Below are the most essential aspects of crowd health during the Hajj season:
1. Prevention of infectious diseases
Preventing infectious diseases is one of the most important pillars of crowd health due to the ease of transmission in crowded places. The measures followed include:ACYW)
Encouraging prior vaccination, such as:
One dose of the meningococcal vaccine (quadrivalent ACYW)
One dose of the COVID-19 vaccine
One dose of the seasonal influenza vaccine
Periodic health surveillance among pilgrims.
2Providing personal protective equipment such as masks and sanitizers.
Health education on modesof disease transmission andmethods of prevention.
2. Preparedness for health emergencies
This means full readiness to face any emergency that may occur suddenly, such as fainting, injuries, or heatstroke, and this preparedness includes:
Field medical teams deployed in vital locations to provide immediate medical care in gathering places and areas prone to incidents.
Mobile ambulance points to ensure rapid access and first aid, in addition to transferring cases to hospitals when necessary.
Urgent response plans for incidents and disasters, including clear mechanisms to deal with major health crises and effective coordination among all concerned entities.
3. Environmental health
It is the key factor in ensuring a clean and healthy environment for pilgrims, and includes:
Securing clean and safe drinking water.
Providing adequate sanitation facilities.
Effective waste management to prevent the spread of pollution and diseases.
4. Communication and health education
Health awareness is a fundamental pillar of crowd health by delivering health information in a simple and clear manner to pilgrims from different nationalities, and includes:
Multilingual awareness media campaigns.
Promoting positivehealth behaviorsamong pilgrims.
- Guiding pilgrims to locations where health services are provided.
What are the health risk factors in crowd management? - Transmission of infectious diseases:
This occurs due to crowding and poor ventilation, especially at entry and exit points or service areas, which increases the likelihood of infection spreading among pilgrims. - Heat stress and dehydration:
Results from prolonged exposure to sunlight, or lack of ventilation and insufficient fluids, and poses a particular risk to the elderly and children. - Neglect of vulnerable health groups:
Includes people with disabilities, those with chronic diseases, or those who have mobility or learning difficulties and who need special care and follow-up. - Difficulty accessing emergency medical services:
May result from congestion or poor planning of ambulance and rescue routes, which hinders rapid response to emergencies.
Random crowd behavior in emergencies:
Such as panic or stampedes, which may lead to injuries or even deaths.
- What steps should be followed to prevent health risks and manage your wellbeing during Hajj?
- To prevent health risks associated with large gatherings such as Hajj, a comprehensive approach based on four phases should be followed: planning, preparedness, response, and recovery. Coordination with relevant authorities such as the police, civil defense, and emergency services is also essential to ensure your safety and the safety of everyone.
- Make sure to review your health status, take the required vaccinations, and carry necessary medications with you.
- Follow official instructions and move within designated routes to avoid crowding and stampedes.
- Use personal protective equipment, such as masks and sanitizers, to reduce the risk of infection.
- Get informed: learn the locations of health centers and emergency exits at the holy sites.
Learn basic first aid and how to act in cases of stampede or heat stress.
Report any health emergency immediately via the unified number (911) or go to the nearest health center.
Misconceptions in crowd health:
Despite ongoing awareness efforts, some misconceptions still affect pilgrims’ safety and expose them to risks during the Hajj season. Below are the most prominent of these misconceptions and their corrections:
Misconception:
“The mask is unnecessary outdoors.”
Correction:
In open but crowded places, the likelihood of infection transmission remains through droplets during talking or coughing; therefore, masks remain an effective means of prevention, especially in highly crowded areas.
Misconception:
“There is no risk to people with chronic diseases during gatherings.”
Correction:
People with chronic diseases such as diabetes, asthma, and heart diseases are more susceptible to complications during gatherings, especially with high temperatures and physical exertion, which requires special care and follow-up.
Misconception:
“Sun heat prevention is not a health priority.”
Correction:
Heat stress and sunstroke are among the most prominent health risks associated with direct exposure to heat during the Hajj season, and prevention starts with providing adequate drinking water, shaded areas, and avoiding prolonged exposure to sunlight.
