I. Kakaretso ea Vaerase le Mefuta ea Pathogen
Li-Hantavirus ke sehlopha sa livaerase tsa RNA tse tsamaisoang haholo-holo ke litoeba, tse leng tsa mofuta oa Orthohantavirus lelapeng la Bunyaviridae. Jenome ea tsona e entsoe kalikarolo tse tharo (L, M, le S), e kenya RNA polymerase e itšetlehileng ka RNA, li-glycoprotein, le protheine ea nucleocapsid, ka ho latellana. Ho latela kabo ea libaka le lipontšo tsa kliniki, li-hantavirus li arotsoe ka lihlophalihlopha tse peli tse kholo:
Li-hantavirus tsa Lefatše la Khale(e fumanoang Europe, Asia le Afrika) sesosaFeberu ea Mali e nang le Lefu la Liphio (HFRS). Livaerase tse emelang li kenyelletsa kokoana-hloko ea Hantaan (HTNV), kokoana-hloko ea Seoul (SEOV), le kokoana-hloko ea Puumala (PUUV). Li shebana haholo-holo le liphio, e leng se lebisang ho holofaleng ha liphio, ho tsoa mali, le maemong a boima, ho tšoha. Sekhahla sa lefu la bakuli se fapana ho latela mofuta oa kokoana-hloko empa ka kakaretso se fapana ho tloha ho<1% ho isa ho 5-15%.
Likokoana-hloko tsa hantavirus tsa Lefatše le Lecha(e potoloha Amerika Leboea le Boroa) sesosaHantavirus Pulmonary Syndrome (HPS). Livaerase tse emelang li kenyelletsa kokoana-hloko ea Sin Nombre (SNV) le kokoana-hloko ea Andes (ANDV). Haholo-holo li shebana le matšoafo, li baka ho ruruha ha matšoafo ho sa amaneng le pelo, ho hema haholo le ho senyeha ha pelo. Matšoao a pele a tšoana le ntaramane (feberu, myalgia, mathata a mala), empa lefu lena le ka fetela kapele ho hloleheng ha ho hema, kasekhahla sa lefu la linyeoe se fihla ho 30-50%.

IV. Global Hantavirus Contacting – Teko le Tatellano ea Nucleic Acid e le Theknoloji ea Bohlokoa
Kamora ho qhoma ha ANDV, balaoli ba bophelo bo botle linaheng tse fetang leshome - ho kenyeletsoa Spain, United Kingdom, United States, Canada le Switzerland - ka nako e le 'ngoe ba ile ba qala ho latela batho ba nang le tšoaetso le ho beha leihlo batho ba nang le tšoaetso ka thoko. Fora, United States le tse ling li ntse li tsoela pele ho latela boemo ba bophelo bo botle ba baahi ba tsona ba khutlileng sekepeng se amehileng.
Karabelong ena ea maemo a tšohanyetso ea linaha tse ngata,tlhahlobo ea nucleic acid le tatellano ea genomicba bapetse karolo ea bohlokoa haholo:
-Teko ea asiti ea nyutleliee fana ka bopaki bo tiileng bakeng sa ho tsebahatsa kokoana-hloko ka potlako;
-Tatellano ea genomee fana ka bopaki bo ke keng ba nkeloa sebaka ba limolek'hule bakeng sa ho latela mohloli oa tšoaetso, ho tiisa liketane tsa phetisetso, le ho lekola liphetoho tsa vaerase.
