О ковиде и клетках памяти

Есть парочка обзоров по иммунологии ковида, и там есть о том, что  гуморальный ответ на коронавирус - слабый, зато надежды вроде бы подает клеточный иммунитет..
Но мне они показались не очень убедительными касательно проявленного оптимизма по поводу Т-клеточного долговременного имунитета как способа защиты от ковида. Часть первоисточников из этих обзоров я читала: и  пришла несколько к другим выводам, чем авторы обзоров. Потому надежды про то, что "нам поможет Т-клеточный иммунитет" мне (пока что) кажутся  хватанием за соломинку.

Во-первых, потому что, ( Read more... )

На заметку путешественикам по США

Americans who live in 33 states — two-thirds of the country — should not be traveling right now, according to the risk-assessment map run by the Harvard Global Health Institute and Brown School of Public Health. The color-coded map provides a simple way for Americans to assess that risk. Each state has a rating of green, yellow, orange or red, based upon the number of new daily cases of Covid-19 per 100,000 people over a seven-day rolling average. States colored red or orange are over the threshold for allowing non-essential travel, according to the scientists.

Based on the tracker’s latest data, six states — North Dakota, Wisconsin, South Dakota, Arkansas, Missouri and Oklahoma — are now colored red, which means they have 25 or more new positive Covid-19 cases every day per 100,000 people. Those states are “at a tipping point” and should be under stay-at-home orders, according to the Harvard and Brown researchers.
Twenty-seven states are colored orange on the map, which signifies they have 10 or more new daily positive Covid-19 cases per 100,000 people over a seven-day rolling average. These states are experiencing an “accelerated spread” of Covid-19, with “stay-at-home orders and/or test and trace programs advised,”
Yellow means there is between one and nine new cases of Covid-19 each day per 100,000 people, which still signifies community spread.
Only Vermont is in the green zone, which means fewer than one new daily case per 100,000 people. That signifies that the disease is “on track for containment.”
