Air Quality and Zoonotic Bugs

Air quality is a crucial part of the equation that factors into our health. Zoonotic diseases, those that pass from species to species – move through the air. Wind patterns, humidity, temperatures; they all play a role in how viruses move. Far too often we are singularly focused on hard-surfaces contamination and its impact. Make no mistake, that is important to understand and address. But it should not be done at the expense of ignoring the importance of airborne transmission. All modes of transmission should continually be evaluated, and infection control plans designed accordingly.

Today we will explore diseases and their travel through the air. Within the past decade, wind influences on Kawasaki Disease were noted. The disease primarily affects children less than 4 years old. The disease causes arterial inflammation, also affecting lymph nodes and mucous membranes. More on the disease and its potential to travel through the air can be found at the links directly below.

Kawasaki Disease is not alone in its ability to move about through the air. Meningitis outbreaks have been linked to wind and dust levels. Those factors have been shown as predictors of seasonal outbreaks. Avian influenza is another that seems likely to ride the wind from place to place.

In the West and Southwest United States another airborne fungi – Fungal Disease Valley Fever – has significant impact on humans and animals. It grows in the hot soil and is so light it can be moved easily when the soil is disturbed, for example by wind, construction or farming. The studies and work done to further understand the growing Valley Fever certainly will be valuable as we endeavor to understand and combat any number of diseases that moves through the air.s
