Agora está confirmado: o sapato pode ser o grande disseminador do vírus chinês:

O CDC, Center for Disease Control and Prevention, dos Estados Unidos publicou uma pesquisa realizada por cientistas e médicos no hospital de Wuhan entre fevereiro e março de 2020.

Os especialistas estudaram a disseminação do Covid-19 pelo ar e pelo chão, e constataram que a maior disseminação do vírus se dá pelo chão, onde repousam as minúsculas gotículas que saem da boca de uma pessoa infectada.

Particularmente, na UTI onde estavam os pacientes em estado grave com o vírus chinês apontaram 43,5% de taxa positiva no ar, enquanto que no quarto comum onde estavam os infectados sem gravidade a taxa diminuiu para 7,9%.

Já no chão, os resultados foram assustadores. Na UTI, a contaminação do chão pelo novo coronavírus foi de 70%, e no quarto comum a taxa foi de 15,4%.

No chão da farmácia do hospital, onde evidentemente não há pacientes, se encontrou a maior concentração do vírus: 100%! O surpreendente volume se explica pelo menor cuidado que se tem na limpeza de locais onde não há pacientes. Muito provavelmente, não utilizam cloro na limpeza desse local. A grande constatação foi que o vírus é transportado pela sola do sapato dos profissionais de saúde, uma vez que nesse hospital não era permitida nenhuma visita aos pacientes. Pelo mesmo motivo, havia vírus no chão de todos os aposentos do hospital, inclusive nas salas dos médicos e das enfermeiras.

Outro foco de grande concentração do Covid-19 foram os cestos de lixo onde se jogam as máscaras usadas. É de se pensar no maior cuidado para o descarte desses materiais possivelmente contaminados.

O estudo revelou também a distância considerada segura para não se contaminar estando perto de uma pessoa com o vírus: 13 pés, aproximadamente 4 metros, enquanto a OMS recomenda 3 pés (1 metro) e a CDC recomenda 6 pés (2 metros). De qualquer forma, seria muito mais seguro se todos usassem máscaras, como na Ásia.

Veja na tabela a proporção de infectados por 1 milhão de habitantes. Certamente, deve haver outros motivos para essa diferença na propagação do vírus entre os países, mas a questão da contaminação pelo chão não deve ser descartada. O Japão é criticado por só fazer o teste do Covid-19 nas pessoas que apresentam os sintomas, assim como o Brasil, e que o número deverá ser muito maior na realidade, mas os Estados Unidos também adotam o mesmo procedimento, assim como muitos países europeus, e mesmo assim, o número de contaminados é muito maior no Ocidente.

世界保健機関(WHO)の3月29日のデータによると、日本では新型コロナウイルスの感染者数1693人、死亡者数52人。イタリアの92,472件、死亡者数10,023人、米国の103,321件、死亡者数1668人(2020年3月29日のWHOデータ)と比較すると数字は小さい。日本では1月15日に最初の感染者が発生して、学校が臨時休校になりましたが、今では北海道など小中学校の登校を再開した地域もあります。

日本は世界で高齢者が一番多い国、なぜ感染者数は少ないのでしょう。日本人の生活習慣が、他の国のように新型コロナウイルス感染が拡大しないようにしているのかもしれません。靴を履いて家に入らないというのは、そのような習慣の一つです。寺や神社の建物に入るときもそうですし、校舎(大学を除く)の入り口では靴を脱いで上履きに履き替えることが習慣になっています。

主要メディアではほとんど語られていませんが、ヨーロッパでは家を出ない高齢者がCOVID-19に感染していると指摘されています。高齢者に食事を持っていく子供や介護者は、アルコールジェルで手を消毒し、高齢者には近寄らず、家のドアノブや手すりの掃除にも気を配っています。でも、靴は脱いでいません。これが大問題です。

家の外では地面に唾を吐いたり、嘔吐したり、タバコの吸い殻を捨てたりする人がいますし、犬や猫が路上でおしっこをしたり、糞をしたりしています。歩道から家の中に入った人は、この汚れやウイルスを靴で運んでいます。外出しない高齢者は歩道との接触はないかもしれませんが、ペットや子供が足をつけたソファに座ったり、床から拾ったボールやおもちゃをソファに置いたりすると、汚染の可能性があります。

世界の人々への実用的なヒントは、靴を脱いで玄関に置いておくことと、家の中を歩くためのスリッパを用意することです。水で溶かした漂白剤で湿らせたタオルを床に置いておけば、靴の裏からウイルスを排除する解決策になります。漂白剤の塩素は70度のアルコールよりも効率的だと言う専門家もいます。

靴を脱ぐ習慣だけではない

日本人は遠慮するから何時も控えめですね。それも新型コロナウイルス感染が拡大しないことと関係があると思います。例えばイタリアとかブラジルでは直ぐハグとかキスをする習慣があります。家に帰ったら子供にキス、お祖母ちゃんにもキス。男友達同士はハグ、ビジネスでも初めて会った人と握手は当たり前です。

各国の習慣は理解できますが、ヨーロッパでの新型コロナウイルス感染の拡大との関係が疑われるエピソードがあります。中国武漢市から始まったCOVID-19で世界的に大騒ぎになって、米国のトランプ大統領は中国人や中国から来た人の入国規制を決めましたが、これに反対するため、フィレンツェ市ダリオ・ナルデラ市長(イタリア、トスカーナ州の州都)が2月1日、「中国人に対して一部の人が行う心理的なテロや略奪行為は許されない」と発言して#abbracciauncinese(中国人にハグをしましょう)と言うキャンペーンをツイッターで始めました。自分たちは差別をしないことを示すためです。リンクは当時のトスカーナ州の新聞記事です。そのキャンペーンに基づいて中国人がイタリアの大都市の広場で手書きの看板を抱えてハグやキスをもらうシーンがSNSで投稿されるようになりました。下のビデオは中国のテレビ局が報道しているもので一人の青年しか映っていませんが、沢山の中国人が集まっている所もありました。

このキャンペーンのせいでイタリアがヨーロッパで一番感染者の多い国になったとは言えませんが、このようなことはしない方が良いと思います。もちろん中国サイドは大歓迎してそのことを大きく宣伝しています。

There are 1.089 confirmed cases of the new Coronavirus and 41 virus’ related deaths in Japan according to data from March 23 of the World Health Organization (WHO). These numbers are small compared to 59.138 cases with 5.476 deaths in Italy, and 31.573 cases with 402 deaths in the United States (WHO’s data in 23/3/2020). Although Japan is one of the first countries hit by the fatal virus, and is the first to ask schools to anticipate vacations, no quarantine was declared in any city and now several schools are already resuming classes. What has this country done differently to have this result?

Perhaps daily habits of Japanese people helped avoid spreading the virus as fast as in other countries. Never going into the house wearing shoes on is one of those habits. It is customary to take your shoes off also when entering temples, businesses and schools (except in universities).

Little is said about that in mainstream media, but it has been noted in Europe that there are elderly people who never left home since Coronavirus outbreak began and yet they were infected. Their children and caregivers take them clean food and groceries, scrub gel sanitizers on hands before entering their house, disinfect elevator buttons, doorknobs and handrails, in short they do everything right. But they don’t take their shoes off. And that is a big problem.

There are people who spit, vomit and throw cigarette butts on the floor. Dogs and cats pee and poop on streets, rats and pigeons do the same. Whoever steps on the sidewalk and enters the house is taking inside dirt, bacteria and viruses on shoes. Elderly people may not have contact with the sidewalks, but if they sit on a sofa where pets, children or teens have put their feet on, or put on the sofa a ball or toys picked up from the floor, contamination is possible.

In countries where taking off shoes is not usual experts are trying to create a new antivirus habit. One simple tip is taking off your shoes, leave them at your entrance and have a pair of slippers to use inside the house only, like Japanese do. Another tip is to leave a towel moistened with a solution of water and chlorine bleach inside a cat sand tray and step on that towel before entering the house to disinfect shoes’ soles. Chlorine bleach is more efficient than 70º alcohol for that situation, say the experts.

The habit of taking shoes off

In the past, in the Jomon Era, ancestors of the Japanese people lived in huts, where in its center they dug a circular hole in the ground. The hole measured approximately 40 cm deep, and wooden stakes forming a cone were placed and covered with straw or other kind of dry vegetation. By keeping fire burning in the central hole, the family settled comfortably despite of the cold. When they started to cultivate rice, it was necessary to build garners to storage food for wintertime. These garners were built on an elevated platform to allow ventilation and avoid humidity.

People started to build their houses also on a platform when they started to use wooden floors or straw tatami. Their shoes/sandals, usually filled with dirt, could not be worn inside the house because the tatami is difficult to be cleaned up, so they started to reserve a space at the entrance for taking off and leaving shoes.

Known as genkan, that space can have a closet to store shoes and it is always one or two steps below the level of the rest of the house. The postman or anybody who is going to deliver or remove something from the house stay at the genkan and does not go that step up. That is why entry doors always open outwards in Japan (if doors were opened inwards like in western countries, a dweller could eventually be hurt at the genkan when someone opens the door).

It is believed that the habit of leaving shoes outside is very old, and in drawings from Heian period it is possible to realize that it was not common to invite people to step on the platform of the houses. Being invited to enter a house, which meant to step on the platform, was an honor and bringing dirt into the house was extremely offensive considering the house’s master’s kindness in allowing entry. The Japanese culture of sitting and sleeping on futons placed directly on tatami, partly because of earthquakes, is also coherent with the custom of keeping the floor always clean.

Contemporary Japanese houses have genkans, even if it is a tiny one and all the rooms in the house are western styled, with hard floors, chairs and beds. And when someone invites you in, they say agattekudasai, which means ‘come up, please’.
