Why is the new coronavirus more dangerous than the mundane flu viruses?  It has to do with RNA sequencing or, more simply, genetics. Seasonal flu is an “all human virus”. The DNA/RNA chains that make up the virus are recognized by the human immune system. This means that your body has some immunity to it before it comes around each year. Novel viruses  come from animals. The WHO tracks novel viruses in animals, (sometimes watching for mutations for years). Usually these viruses only transfer from animal to animal (pigs in the case of H1N1 and  birds in the case of the Spanish flu). But  these animal viruses can  mutate and start transferring  from animals to humans. Then it’s a problem, because we have no natural or acquired immunity.  The RNA sequencing of the genes inside the virus isn't recognized by the human immune system. So, we can’t fight it off. Sometimes, the mutation only allows transfer from animals to humans. For years its only tran...

How Coronavirus affects the body: What is a virus: A virus is a small parasite that cannot reproduce by itself. Once it infects a living s cell, however, a virus can direct the cell machinery to produce more viruses. What is Coronavirus: The name “coronavirus” comes from the crown-like projections on the surfaces of these viruses  “Corona” in Latin means “halo” or “crown.” Among humans, coronavirus infections most often occur during the winter months and early spring. People regularly become ill with a cold due to a coronavirus and may catch the same one about 4 months later. This is because coronavirus antibodies do not last for a long time. Also, the antibodies for one strain of coronavirus may be ineffective against another one. In 2019, the Centers for Disease Control and Prevention (CDC) started monitoring the outbreak of a new coronavirus, SARS-CoV-2, which causes the respiratory illness now known as COVID-19. Authorities first identified the virus in Wuhan, China...

He was awarded the prestigious Padma Shri in 1990 and was named Indian Footballer of the 20th century by IFFHS. In 2004, he was awarded the FIFA Order of Merit, the highest honour awarded by FIFA. P.K. was born on 23rd June 1936 in Jalpaiguri in  Bengal Presidency (now West Bengal). At the age of 15, Banerjee represented Bihar in the Santosh Trophy, playing on the right wing. In 1954 he moved on to Kolkata and joined Aryan.  He made his debut for the national team in the 1955 Quadrangular tournament at the age of 19. He made 84 appearances for India, scoring 65 goals during the course of his career. He represented India in three Asian Games -  the 1958 Asian Games in Tokyo, the 1962 Asian Games in Jakarta, where India clinched the gold medal in football and then the 19...

Scientists and medical researchers have for years have differed over the exact definition of a pandemic, but one thing everyone agrees on is that the word describes the widespread occurrence of disease, in excess of what might normally be expected in a geographical region. Cholera, bubonic plague, smallpox, and influenza are some of the most brutal killers in human history. And outbreaks of these diseases across international borders, are properly defined as pandemic, especially smallpox and plague, which throughout history, have killed around  500 million people. The following are the most series diseases that have afflicted the world during human history: COVID-19 has resulted in 13054  deaths as of 23rd  March 2020. [The toll is over 27000 as of 28th March 2020. In just five days, the number of deaths have more than doubled.] MERS (2015 - Present) has caused 850 deaths.  EBOLA (2014-16) led to 11000 mortalities.   SWINE FLU (2009-10) caused abou...
