Dear reader:

Worldometer (August 10): Over 20 millions cases and over 736 thousand deaths worldwide. Over 5 million cases and getting close to 166 thousand deaths in the U.S., almost 48 thousand new cases and 534 new deaths yesterday, Aug 9 (significantly fewer deaths in the U.S., and in each one of the three states at the epicenter of the recent wave: California, Florida and Texas).

Over 3 million cases and over 101 thousand deaths in Brazil, significantly fewer new cases and new deaths yesterday than in each day from Aug 4-Aug 8.

Close to 2.3 million cases and over 45 thousand deaths in India, number of new cases and new deaths yesterday are still on the rise.

Best Life, Dr. Fauci says this is how the U.S. can avoid a ‘catastrophe’ this fall(Aug 10): “While mask-wearing, social distancing, and stay-at-home orders have helped other countries stem their coronavirus epidemics, the U.S. has seen record-breaking numbers of new Covid cases since the pandemic began- and rising death tolls, as well. In fact, people in the U.S. are dying of the coronavirus at a rate of over 17 times faster than people in Canada and Europe…

“on Aug 7, Fauci said that if people can begin to view the public health principles as a step toward reopening the country, rather than as a means of control or a step backward, Covid-19 numbers could be in a much more manageable place in the next few months… Fauci noted that if people follow recommended public heath measures, ‘we could go into the fall and the winter looking good.. we do not have to completely lock down if we do things right… I believe we can open up the economy, get the employment back.. if we do it prudently, carefully, and the way the guidelines say’.. like staying home and wearing masks, seriously, or the numbers will continue to rise.

“‘It never turns around spontaneously unless you do something different than you’re doing,’ he explained.”

Wikipedia, Adaptive Immune System, paraphrased with quotes): the adaptive immune system, also referred as the acquired immune system, is part of the immune system that is made of specialized cells and processes that eliminate pathogens by preventing their growth. Acquired immunity creates an immunological memory that leads to these specialized cells being produced in future infections. The specialized cells are specifically made to target specific pathogens (unlike the innate immune systems where cells attack a variety of pathogens, not having been designed to attack a specific pathogen).

“Unlike the innate immune system, the acquired immune system is highly specific to a particular pathogen. Acquired immunity can also provide long-lasting protection”, sometimes providing a lifetime protection (measles), and at other times less than a lifetime protection (chickenpox). Sometimes the specialized cells designed to attack specific pathogens, attack the human cells as well and asthma and allergies result.

The cells that carry out the acquired immune response are white blood cells known as lymphocytes. Two types of lymphocytes are B  cells and T  cells. B cells secret antibodies that travel through the bloodstream and bind to the pathogen, inactivating the pathogens, so that they are unable to bind and infect the human host cells.

More, later.
