As the nationwide measles vaccination drive gains momentum, large crowds have been reported at centres across the country, raising concerns about potential infection risks during public gatherings.
While the rush reflects growing awareness among parents seeking to protect their children, experts warn that crowding at vaccination sites could increase the risk of transmission of measles, a highly contagious viral illness.
How measles spreads
Health experts say measles spreads easily from person to person through respiratory droplets. When an infected individual coughs or sneezes, the virus can remain airborne for several hours.
This means people can become infected by being in the same room or even by touching contaminated surfaces such as door handles or toys and then touching their face.
Risks at crowded centres
Vaccination centres, particularly those serving children, often see long queues and crowded waiting areas.
Experts caution that individuals who are infected but not yet showing symptoms can unknowingly transmit the virus to others—especially those who have not yet been vaccinated.
Importance of crowd management
Although vaccination remains the most effective protection against measles, poor crowd management and lack of personal precautions can increase exposure risks.
“The risk lies not in the vaccine, but in unmanaged crowds and lack of hygiene practices,” health experts noted.
Precautionary measures
To reduce the risk of infection, experts recommend several preventive steps:
- Visit vaccination centres during less crowded hours
- Avoid attending if the child or guardian has fever, cough, or other symptoms
- Maintain physical distance where possible
- Wear masks in crowded settings
- Wash hands frequently or use hand sanitiser
Open vs enclosed spaces
Centres located in open or well-ventilated areas pose a lower risk compared to enclosed, poorly ventilated environments, where transmission is more likely.
Balancing safety and protection
Despite the risks associated with crowding, experts stress that vaccination remains essential to prevent measles outbreaks.
They say a combination of timely vaccination and adherence to basic hygiene measures can significantly reduce infection risks and help control the spread of the disease.
