The Haze is an important health issue, but it is equally important not to mislead others more so with the title on this thread.
Based on Science, regardless of vaccinated or not vaccinated, the Haze will affect ALL, Vaccination status is irrelevant to the effects of dust & dirt particles upon Humankind respiratory system.
1.The ones whom will be severely affected will be those with respiratory health issues. Thus they must wear masks whenever outside.
2. Do not plan any exercise programs outdoors when the haze abounds, as it will cause breathing problems, such as school PE lessons or civilian sunset walks.
3. Air purifier works, but so too a strong fan which can circulate air currents within a room or apartment that has at least minimal opened ventilation windows when haze levels are at the moderate range. Beyond that, fixed aircon or portable aircons will be needed for air circulation when windows are sealed.
Should one be infected with COVid during the haze period, regardless if vaccinated or not, it is critical to ensure patient if recovering at home, be placed in a clean environment - such as an aircon room with air purifier & windows/doors sealed to prevent any haze particles from entering, so as to assist the patient to breathe better.
