In fact, according to educational materials from the Taiwan Centers for Disease Control, the primary route of transmission is inhalation through the respiratory system.<\/p>\n\n\n\n<p>When infected rodents\u2014such as sewer rats or roof rats\u2014leave urine, droppings, or saliva in the environment, these contaminants can dry out and become aerosolized as dust particles. When individuals inhale these airborne particles while cleaning contaminated areas or staying in poorly ventilated enclosed spaces, the risk of infection increases significantly.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Hidden_Vulnerabilities_in_Industrial_and_Commercial_Buildings_Ventilation_Systems\"><\/span>Hidden Vulnerabilities in Industrial and Commercial Buildings: Ventilation Systems<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>In factories, warehouses, and older office buildings, rodents often travel through piping systems, HVAC ducts, and ceiling voids. If a building\u2019s ventilation and filtration systems are inadequate, or if filters are not replaced regularly, virus-carrying particles may circulate throughout indoor spaces via the central HVAC system.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_Should_Your_Air_Filters_Be_Upgraded\"><\/span>Why Should Your Air Filters Be Upgraded?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>To reduce the risks associated with airborne pathogens such as Hantavirus, businesses should review and upgrade their existing filtration systems:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Capture_Fine_Dust_Particles\"><\/span>Capture Fine Dust Particles<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Hantavirus particles are commonly attached to dried waste dust smaller than 5 microns in diameter. Standard pre-filters can only capture larger particles. It is recommended to use at least MERV 13-rated filters, or even HEPA filters (with 99.97% efficiency or higher) in critical areas, to effectively capture contaminated aerosols and fine particles.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Reduce_Indoor_Dead_Zones\"><\/span>Reduce Indoor Dead Zones<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Proper ventilation and a high Air Changes per Hour (ACH) rate help dilute indoor contaminants and reduce employee exposure risks.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Prevent_HVAC_System_Contamination\"><\/span>Prevent HVAC System Contamination<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Regular replacement of filters inside Air Handling Units (AHUs) prevents dust accumulation in air ducts, reducing the likelihood of ducts becoming nesting and contamination sites for rodents.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Three_Practical_Strategies_for_Hantavirus_Prevention\"><\/span>Three Practical Strategies for Hantavirus Prevention<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>To ensure workplace and facility safety, we recommend combining environmental control measures with advanced air filtration strategies.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"1_Implement_the_%E2%80%9CThree_Nos%E2%80%9D_of_Rodent_Prevention\"><\/span>1.
