Measles is a highly contagious virus that can spread through microscopic saliva droplets expelled when an infected person coughs, sneezes, speaks, or even breathes. According to health officials, an infected individual can transmit the virus even before showing symptoms, making it more dangerous than many other respiratory infections. Current statistics from the General Directorate of Epidemiology in Mexico indicate that these micro-droplets can remain suspended in the air for up to two hours and can also remain viable on surfaces for more than 48 hours, creating a risk for transmission long after the infected person has left the area.

Jorge Baruch Díaz, head of the Traveler's Clinic at the National Autonomous University of Mexico (UNAM), emphasizes the unique characteristics of measles transmission compared to other respiratory viruses. Unlike many other pathogens, measles remains airborne longer and does not settle rapidly to the ground, allowing for more extensive spread in public spaces. This characteristic highlights the importance of preventive measures, especially in crowded environments where outbreaks can occur more frequently.

The implications of this understanding are significant for public health, particularly in relation to vaccination campaigns and awareness initiatives. As measles outbreaks continue to be reported globally, Mexico must emphasize the importance of vaccination and health safety practices to mitigate risks associated with this contagious disease, especially for vulnerable populations such as children and those with compromised immune systems.
