The Importance Of A Bird Flu Mask
Even so the avian influenza virus is hosted by birds, certain particular subtype might affect other mammals too, together with humans. In a direct manner the virus is contacted right from infected birds, mostly domestic poultry but sometimes undomesticated birds also can infect hunters, tribal people, etc . Inside an indirect manner the infection can enter the human system using edibles infected with the virus, polluted water, objects, fresh air, food, etc . by the bodily secretions or excretions for infected birds. The flu virus being airborne, often the contamination in the air could be reasonably high, in cases of epidemic as well as pandemic proportions. Infected people carry the flu disease with them wherever they travel and spread it on air and on objects they touch via their nasal secretions and bodily discharges.
Personal Protective Equipment or simply PPE as they are called are equipments designed for health professionals to utilise if they are working in contaminated environments. Nose and mouth respirators or ‘Masks’ are the ones most widely used. Bird flu masks are very specific pertaining to the fact that the bird flu computer virus is microscopic and is not easily filtered out from the conditions using conventional filters.
These masks are designed on the regulations given by National Institute for Occupational Safety and Overall health (NIOSH). Based on filtering efficiency, the filters used in the exact masks fall under 3 categories, namely Type 95, Model 99 and Type 100. The proportions of health issues (0. 3 micron wide) particles filtered out by just these filters are 95%, 99% and 99. 7%, respectively. Also the filters are categorized based on clean efficiency degradation and are hence labeled as, N ( non-resistant to oil), R (oil resistant) and P (oil proof). Each individual KN95 Protective Mask is tested in laboratory configuration settings before being approved for sale. But N95 ones are use-and-throw and cannot be cleaned.
The most common ones are N-95 selection respirators which have been approved by NIOSH (also called as Selection Facepieces) as being effective drastically cutting down exposure risks towards airborne viruses like SARS or Avian Influenza. The effective use of masks is recommended to people working in high contamination situations, including health care workers attending to patients, or field workers related to destroying the infection sources, etc .
Another set of very powerful, defending masks are Powered Air-Purifying Respirators (PAPRs). They are more potent than N-95 masks in offering better protection. These include used by persons who cannot wear N-95 masks, for instance people with facial hair. This battery operated mask has a point piece with breathing tube and filters.
Even though every mask is not a guarantee against influenza infection, they noticeably cut down the chances of infection from airborne viruses. It remains to be said however , that the capabilities of the masks degrade in time from usage. Aerosols, if present in the working environments, decline the filters even more. Hence, bird flu masks really should not used with 100% reliance, but only as one of the preventive product. More so, there are guidelines that need to be adhered to while (re)using these types of PPE. It is hence clear that the best defense fails to lie in any amount of measures taken but rather in the awareness with which they are implemented
