coronavirus or epidemic?........
The novel coronavirus has probably been spreading undetected for about six weeks in Washington state, where the first U.S. death was reported this weekend. A genetic analysis suggests that the cases are linked through community transmission and that this has been going on for weeks, with hundreds of infections likely in the state. s
The global death toll is climbing toward 3,000 on four continents. The first U.S. death, in Washington state, was man in his 50s with underlying health conditions, officials said. The patient had no recent travel history or contact with people known to be infected, officials said.

Scientists have found some toxic DNA lurking inside a virus that infects bacteria. In addition to its own genes, the virus holds a gene for
black widow spider venom and DNA from other animals, the researchers found. The findings suggest that either the virus snagged this foreign genetic material or that these other animals have stolen DNA from the virus, the researchers said.
Future research could find that such swapping across domains of life, from the most complex to the most ancient, is more common than previously thought, scientists say.
Viruses infect all three domains of the tree of life. The most complex forms of life on Earth — including animals, plants and fungi — belong to the domain
Eukaryota , whose cells possess nuclei. The other two domains include the prokaryotes, the earliest forms of life — single-celled microbes that lack nuclei. There are two prokaryotic domains — the familiar Bacteria, as well as Archaea, which includes microorganisms that thrive in harsh environments such as hot springs and underground petroleum deposits.

Each virus
infects just one domain of life. For instance, bacteriophages, which are viruses that attack bacteria, cannot infect eukaryotes, or cells with nuclei. In part due to this specificity, scientists have explored using these so-called "phages" in therapies to kill antibiotic-resistant bacteria .
