Vawikhat kan hahchhiau hian chil leh hnap si per (droplets) te tak te te, mit lawng hmuhtham loh, sing thum vel teh meuh mai, darkar khat a mel 200 a chak in kan phuh chhuak thei a. Vawikhat kan khuh hian chil per sang thum vel kan phuh chhuak thei thung.



Thawk pangai a boruak kan thawk chhuah ah hian, a si per 50 atanga 5000 vel a chhuak ve leh thei a. Mahse hahchhiau leh khuh vel ang lo takin, a si per te hi thui tak kan phuh darh ve lo thung. A si per a tlem mai bak ah, in hnit leh hrawk za vang te a nih loh avangin, thawk chhuah ngau ngau ah pawh hian a hrik pawh a tel tlem zawk hle. Heng si per te hi size hrang hrang in an per chhuak thei a, a lian zual te chu lei ah an tla ve mai a. Mahse a si per te leh zual te chu boruak ah cham bangin, rei lo teh ah room chhung ah a leng darh thin a ni. Dam lo hrikpai khuh leh hahchhiau si per pakhat lek pawh hian, a virus maktaduai zahnih dawn lai a keng tel thei thung a ni!

Pawimawh ta chu, a lo berah virus 1000 vel tal hip luhin hri a thlen thei a!. 
A hlawm in em maw, zawi zawi a, sangkhat tlin khi thil awm thei a nih avangin (frequency + exposure time), engtia rei nge kaipalh theihna hmun a kan awm tih leh, engzat chiah nge a hrik kan hip luh tih ah a in nghat a ni. A hri kai tawh in, vawikhat lek pawh hmai chhan ah min khuh khum emaw hahchhiau khum chuan a virus load a san em avangin, kai na chance a sang hle tihna a ni a. Tawng pah a chil per te tak te te ah hian, minute 1 chhungin a hrik 200 vel kan phuh chhuak tel thei thin a. Sangkhat tlin tur chuan minute 5 tal hmai chhan a inbiakin a hri kan lo kai palh thei tihna a nih chu. Aw rawl ring leh tawng nasa ah chuan hei ai a rei lo deuh pawh a ngai hial ang.


Kan va khel te neuh neuh ve kan ti mai thei a, mahse heng te hi transmission pattern leh contact tracing innghahna lungphum te an ni!. Hetiang a thil inkungkaih dan kan hriat vang tak hian contact tracing ‘awmze nei’ in kan lo kal pui thei dawn tihna a lo ni. Hmaikawr vuah tha, kutfai tha reng tan chuan, positive bul hnai a an awm zawk te, in kal pelh thuak te, room khat pawh ni lem lova building khat a awm vang ngawr ngawr te, veng khat nih vang ngawt te in, mi isolate tur kan tih chuan a chuang tlai lutuk thei. Test vek a, result hriat thuai a nih dawn erawh chuan hetiang chhut si se lova, screen vek a finthlak thung. Anih lova, kan huam zauh tir lutuk erawh chuan test kit leh resources pawn a daih seng lovang. Tin, “trace ho pawh an negative leh vek zel tho sia” kan tih fo nachhan pawh a ni thei.

A si per leng vel hi inchhung room te deuhvah chuan a in pawlhdal har deuh dawn a, inzau tak ah emaw, pawn emaw velah chuan a dal thuai thuai dawn thung, chuvangin kan awmna room len zawng a zir a, kaitheihna chance awm te kan hriat thiam a pawimawh. Mizo insak a, room pangai tak a minute 10 tal awm ho te chauh isolate tur a chhiar tel hi a awm tawk chho viau. An zing a tumah khuh bur bur leh hahchhiau vak vak an awm lem loh phei chuan chance a tlem letling viau thei. Hei vang hian hritlang symtoms nei te chu inkhung hram hram tur a ngen an ni reng a. Tin, hmanni deuhva WHO in asymptomatic hovin midang an kai tlem letling phian an tih nachhan pawh hemi dinhmun hi a ni thei. A tlangpuiin, inchhung uap ang reng tak ah, mi an awm khawm a, an tawng luai luai leh, zai te, au vak vak te an awm hian case pawh a tam phah deuh a nih hmel. 90% vel lai chu, hetiang hmun atang te a in kai chhawng niin an report. Outdoor vel atang a kai tak chu an tlem zawk viau, hmaikawr nen physical distancing nen kan tih that phei chuan a chance a tlem leh zual. Futsal tracing report te pawh kha a hrilhfiah mahna.

Engpawhnise, aerosols transmission leh contact tracing theoretical background chu ti hi a ni mai a. Hri kan lo kai palh a nih pawn kan sulhnu kan chhui kir hunah, chumi khami chu a kai mial mahna, tiin hemi behchhan hian kei mahni ngeiin thutlukna kan siam thei ngei ang. Kan capacity in a dawl rih phawt chuan, fimkhur thu hla ah erawh isolate tur leh tracing kan huam zau tir thei thung.
