Este \u00e9 um t\u00f3pico comum em infectologia: as doen\u00e7as s\u00e3o freq\u00fcentemente trazidas aos seres humanos devido \u00e0 intera\u00e7\u00e3o com animais selvagens. Quem \u00e9 o suspeito desta vez? Uma dica bastante comum: \u00e9 um mam\u00edfero, e voa.<\/p>\n

Os coronav\u00edrus t\u00eam hospedeiros naturais na natureza, e tamb\u00e9m geram doen\u00e7as entre os animais. Os hospedeiros naturais dos coronav\u00edrus s\u00e3o todos mam\u00edferos, portanto, em teoria todos os mam\u00edferos compartilham receptores semelhantes para o v\u00edrus e podem ser hospedeiros naturais.<\/p>\n

Mas o infogr\u00e1fico abaixo traz o que j\u00e1 se sabe a respeito dos hospedeiros naturais do coronav\u00edrus. \u00a0Para informa\u00e7\u00f5es sobre a transmiss\u00e3o \"urbana\", verifique este posto<\/a>.<\/p>\n\n\n\n

\"Coronav\u00edrus<\/p>\n\n\n\n

As doen\u00e7as animais causadas pelo coronav\u00edrus em seus hospedeiros snatural s\u00e3o graves e de uma forma ou de outra, normalmente relacionadas \u00e0 fun\u00e7\u00e3o respirat\u00f3ria. H\u00e1 p\u00e1ssaros, cavalos, ratos, c\u00e3es e at\u00e9 baleias relatados como hospedeiros naturais dos coronav\u00edrus. H\u00e1 realmente um zool\u00f3gico de hospedeiros de animais relatado para esta classe de v\u00edrus.<\/p>\n

Os Coronav\u00edrus apresentam uma \"grave amea\u00e7a global \u00e0 sa\u00fade\", escrevem pesquisadores da Universidade de Wuhan e da Universidade Sun Yat-sen no Journal of Medical Virology. Os v\u00edrus n\u00e3o s\u00e3o novos, nem infectam apenas pessoas.<\/p>\n

De acordo com a literatura veterin\u00e1ria que \u00e9 ilustrada na infografia acima, os coronav\u00edrus j\u00e1 causam tamb\u00e9m:<\/p>\n

Coronav\u00edrus hospedeiros naturais e os sintomas que eles produzem<\/h3>\n

Aves: Infec\u00e7\u00e3o do trato respirat\u00f3rio
Vacas: Diarr\u00e9ia
Gatos: Febre e vasculite
C\u00e3es: Diarr\u00e9ia
Cavalos: Febre e Anorexia
Ratos: Danos Pulmonares Graves
Su\u00ednos: Diarr\u00e9ia
Baleias: Doen\u00e7as pulmonares e hep\u00e1ticas
(ordem alfab\u00e9tica)<\/em>

A lista \u00e9 vasta e inclui animais selvagens, mas tamb\u00e9m animais de fazenda e at\u00e9 mesmo animais de estima\u00e7\u00e3o como hospedeiros naturais dos coronav\u00edrus.<\/p>\n

Oh espere, animais de estima\u00e7\u00e3o? Ent\u00e3o, eu preciso colocar em quarentena meu c\u00e3o\/gato querido? Espere... h\u00e1 outros tipos de coronav\u00edrus, n\u00e3o estamos falando especificamente do coronav\u00edrus Covid-19 neste caso. Outros tipos de coronav\u00edrus<\/span> afetam os animais listados acima. Eles n\u00e3o s\u00e3o necessariamente anfitri\u00f5es do Covid-19. E, o t\u00f3pico ainda \u00e9 controverso, mas voc\u00ea n\u00e3o precisa tratar seu animal como um foco de infec\u00e7\u00e3o por coronav\u00edrus<\/a>.<\/p>\n

Com rela\u00e7\u00e3o ao atual coronav\u00edrus Covid-19, respons\u00e1vel pelo surto global de doen\u00e7as respirat\u00f3rias, alguns pesquisadores acreditam que ele pode ter sido introduzido \u00e0 humanidade pelos morcegos. <\/p>\n

Algumas esp\u00e9cies disseminam coronav\u00edrus sem adoecer, como os camelos portadores da S\u00edndrome Respirat\u00f3ria do Oriente M\u00e9dio (MERS-Cov), tamb\u00e9m causada por v\u00edrus da classe dos coronav\u00edrus. O MERS-CoV tamb\u00e9m \u00e9 eventualmente encontrado em ovinos, caprinos e burros.<\/p>\n

Para a Covid-19, por acaso foram os morcegos. Alguns dizem que as pessoas da regi\u00e3o de Wuhan na verdade se alimentam de ninhadas selvagens. N\u00e3o tenho id\u00e9ia, mas se isso acontecer, este contato \u00edntimo com os morcegos poderia transmitir o v\u00edrus para o \"hospedeiro\" humano.<\/p>\n

A resposta imunol\u00f3gica dos morcegos lhes permite abrigar coronav\u00edrus sem ficar doentes, tornando-os um perigoso reservat\u00f3rio de infec\u00e7\u00e3o. Isto \u00e9 t\u00edpico desta esp\u00e9cie, que normalmente carrega uma grande quantidade de microorganismos diferentes. Os morcegos s\u00e3o hospedeiros naturais de v\u00e1rias doen\u00e7as humanas potenciais,<\/p>\n

De notar que existem evid\u00eancia confi\u00e1vel de que o pangolim \u00e9 tamb\u00e9m outro hospedeiro natural do coronav\u00edrus<\/a>. Um artigo a ser publicado em breve associou uma parte importante do coronav\u00edrus associado ao pangolim com a cepa do v\u00edrus Covid-19. Eles podem ter sido a fonte original de onde ocorreram as muta\u00e7\u00f5es naturais.<\/p>\n

Os mercados de animais em Wuhan s\u00e3o famosos pela venda de pangolins e balan\u00e7as de pangolins. Portanto... h\u00e1 uma conex\u00e3o potencial. A lista de suspeitos aumenta quanto mais profunda for a investiga\u00e7\u00e3o. Portanto, vamos atualiz\u00e1-la de acordo.<\/p>\n\n\n\n
