This invention provides a respirator for detecting viruses which cause respiratory tract infection. The respirator comprises an outer layer, an inner layer, a rapid screening reagent between the outer layer and the inner layer, and a water-resist membrane between the rapid screening reagent and the inner layer. A sample pad of the rapid screening reagent is located on a region close to the nostrils, such that air from the nostrils will arrive the sample pad. Viruses inside the air with vapors or moistures will flow inside the rapid screening reagent through a conjugate pad, a nitrocellulose membrane, and an absorption pad. At least one test line will indicate a corresponding virus.

Wearing a face mask or a filtering facepiece respirator, especially in hot weather for more than one hour, causes discomfort. But, in a viral pandemic, a barrier to filter inhaled and exhaled air is necessary to protect against airborne pathogens. The sensations of heat abstraction, that is, coolness and cold, can be captured by the rational design of optimized molecules called TRPM8 receptor agonists. The topical application of these molecules alleviates the discomfort of wearing a face mask covering. Several entities were identified by synthesis and experiment as having the ideal properties for achieving this purpose. The preferred embodiments are certain 1-diisopropyl-phosphinoyl-alkanes described as DIPA-1-5, DIPA-1-6, DIPA-1-7, DIPA-1-8, and DIPA-1-9, collectively referred to herein as “DIPA compounds.” The applicant found that topical delivery of DIPA compounds to the facial skin, especially to the surface of the nares (nostrils), alleviates face mask discomfort. From these studies, it is hypothesized that it is the absence of cool air dynamics about the nostrils that causes face mask discomfort. The present discovery pertains to pharmaceutical compositions that relieve face mask discomfort.

A personal protection device includes one or two elongate members for engaging into the nostrils of the nose of a user. The elongate members each includes gridded ports for allowing air to pass through the elongate member when breathing in and for allowing air to exit via the elongate member when breathing out. Sensors are placed in the air flow pathway to detect pathogen presence, and the primary air filter is positioned in the elongate member. In yet other embodiments, a disposable version is disclosed. The eyewear can also be used as part of an extended reality system, and when game playing, particularized scents can be rendered to the nose to enhance the gaming experience. In another aspect, systems and methods protect against pathogen by sampling an environment of a travel path with a plurality of pathogen detectors along the travel path to detect a presence of one or more pathogens, wherein at least one detector includes a nano-sensor with receptacles to bind to the pathogens and wherein the nano-sensor changes resistivity, inductance or capacitance upon pathogen binding; directing air towards said pathogen detectors; contact tracing a user mobile device having a mobile identification (ID) carried by each user, wherein the mobile device comprises a memory storing mobile IDs of all devices within a predetermined radius of the user mobile device; and performing deep learning with a neural network receiving data from the pathogen detectors and to the user mobile device to detect a presence of one or more pathogens.
