HIV4

從醫學知識來看,害怕Motel消毒不全,萬一腳上有傷口會感染HIV,是一件很多慮的事情,如果是極度潔癖的人,大不了多帶點75%酒精噴灑,HIV很怕75%酒精,雖然我說可以帶酒精去消毒,但我還是認為根本沒有這個必要。

 

HIV1

HIV在體外保持感染活性15天,依照CDC的及其引用的文獻來看,確實是可以,但那是有前提條件的。

Survival of HIV in the Environment

The most extensive study on the survival of HIV after drying involved greatly concentrated HIV samples, i.e., 10 million tissue-culture infectious doses per milliliter. This concentration is at least 100,000 times greater than that typically found in the blood or serum of patients with HIV infection. HIV was detectable by tissue-culture techniques 1-3 days after drying, but the rate of inactivation was rapid. Studies performed at CDC have also shown that drying HIV causes a rapid (within several hours) 1-2 log (90%-99%) reduction in HIV concentration. In tissue-culture fluid, cell-free HIV could be detected up to 15 days at room temperature, up to 11 days at 37 C (98.6 F), and up to 1 day if the HIV was cell-associated.

 

Stability and inactivation of HTLV-III/LAV under clinical and laboratory environments

這篇文章所提出的條件,HIV濃度要比血液高上1000倍,還要有實驗室環境,既然是實驗室環境,那麼濕度、溫度都必需嚴格限制,才能讓HIV在體外15天還有感染力,現實有辦法做到嗎?

 

菜花之性與不性及污名化一文也提到有人覺得泡澡可能得菜花的問題,加上本篇的去MOTEL得愛滋,有些人就為了這種瞎到不行的因素,還認為應該先清潔MOTEL設備再使用,我會覺得去MOTEL泡澡還要花一個小時清潔設備,這麼辛苦,不如別去MOTEL了,也省的煩惱有的沒的。
