He natna hi mi pakhatin a khuh, a thawk a, a chunga virus awmna hmun a khawih chauhvin a kai theih niin kan ngai vek a. Mahse, thil thleng tlemte chuan kan rinna hmasa zawng zawng chu a tidanglam vek a ni. Chu chu vawiina kan sawi tum chu a ni.
Engkim tidanglamtu thilthleng kha
Hei hi March 2020 khan Washington, USA-ah a thleng a ni. Zaipawl pakhat ‘Skagit Valley Chorale’ tia koh member 61 te chuan darkar hnih leh a chanve chhung practice turin an zawm a ni. Chutih laia hriselna inkaihhruaina zawng zawng an zawm vek a ni. Tumahin midang an khawih lo va, meter hnih vel an hlat a, hand sanitizer uluk takin an hmang bawk.
Mahse mak tak maiin, kar tlemte chhungin heng mi 61 zinga 52 te chuan COVID-19 an kai ta! Mi eng emaw zat chu damdawi inah dah an ngai a, vanduaithlak takin mi pahnih an thi.
Scientist-te chuan a tirah chuan mak an ti hle. Mi zawng zawng chuan, "Engtin nge hetiang hi a lo awm?" An inhlat hle a, an inkhawih lo a, chuti a nih chuan engtin nge vawi khatah mi tam tak an damloh theih?
Chutih lai chuan scientist pakhat chuan, "Chu pindan chhunga mi zawng zawngin thil pakhat chauh an insem a. Chu chu boruak a ni ," a ti a, "Chu boruak kaltlangin natna chu a darh tih rinhlelh rual a ni lo," a ti bawk.
He thil thleng hi Covid hripui chungchanga kan ngaihdan tam tak tidanglamtu thil pawimawh tak a ni.
Chuti a nih chuan, hetiang hian kan ngaihtuah sual tawh em? Hmanlai 'droplet' thlir dan kha
Dik tak chuan, kum za khat vel kalta atang khan hriselna lama mithiamte chuan thawkna lam natna, khawsik leh influenza ang chi hi a bul berah chuan droplet lian leh rit tak tak hmanga darh a ni tih an ring a. A awlsam zawngin sawi ila, mi pakhatin a khuh emaw, a khuh emaw a chhuah huna a hnah (droplets of saliva) a chhuak thin.
He ngaihdan ang hian natna hi a lo awm a, chu chu:
- Damloin a khuh emaw, a khuh emaw a nih chuan i hnaih hle tur a ni .
- A nih loh leh, a chunga tui lian tak tak awmna hmun (table emaw kawngkhar khar ang chi) i khawih a, chu kut ngeia i hnar, i hmui emaw, i mit emaw i khawih chuan i na thei bawk.
He ngaihdan hlui (Droplet Dogma) avang hian Covid hmasa lamah phei chuan feet 6-a hla vawn reng tur leh disinfectant hmanga engkim phihfai vek tura thurawn min pek vang a ni.
Mahse chu zaipawl chunga thil thleng avang chuan scientist-te chuan khawi emaw laiah he thawnthuah hian tlin lohna lian tak a awm tih an hre ta a ni. Natna darh dan tur fiah lo zawk a awm ngei tur a ni.
'Droplet' leh 'aerosol' - eng nge a danglamna?
Hei hi thumal thar - 'aerosol' kan hmuhna hmun a ni. Hei hi hriatthiam a pawimawh hle. Spray bottle pakhat han ngaihtuah teh. I spray chuan tui tla lian tak tak leiah a tla a, chubakah boruakah hian tui chi hrang hrang, hmuh theih loh, vur ang maia inphah a awm bawk a ni lawm ni? Chutiang chu a ni.

Chu zaipawl member-te chuan an hla sak chuan heng thil te te (aerosol) te hi an thaw atangin an chhuak ta a ni.Room pum pui chu boruakin a khat vek tawh ngei ang. An inhlat hle chung pawhin boruak inang an thawk vek a, chuvang chuan mi zawng zawng deuhthaw chu an damlo vek a ni. Hei hi airborne transmission an ti a .
Hriatna tharin kan nun a tihdanglam dan
He thil hmuhchhuah nen hian hripui dona atana kan hman dante chu a danglam vek a ni.
Surface phihfai atanga boruak ngaihtuah thlengin
A tirah chuan, lei, dawhkan, leh kawngkhar kharte phihfai chu thil pawimawh ber niin kan ngai a. Mahse boruakah a awm tih kan hriat hnuah chuan thil pawimawh zawk a awm tih kan hre ta a ni. Tin, chu chu ventilation tha tak a ni.
A awlsam zawngin, kawngkhar leh kawngkhar hawn reng leh boruak kal kual nan fan hman hian hmun khatah virus particle awm zat a tihtlem phah a ni.
Mask hlutna dik tak chu
A tirah chuan kan khuh chhuah tui lian tak takte tihtawp nan mask kan vuah a. Mahse a hnuah chuan N95 ang mask tha tak hian heng boruakah hian heng virus particle te tak te (aerosols) te pawh hi a filter chhuak thei tih an hrechhuak ta a ni.
