How COVID-19 Spreads Person-to-person spread The virus is thought to spread mainly from person-to-person. Some other viruses, like measles, can travel up to 100 feet and stay alive on surfaces for hours. The first individual in the United States to be confirmed as positive for the new coronavirus by the Centers for Disease Control was indeed a resident of Snohomish County, Wash.
In humans, coronaviruses cause respiratory tract infections that are typically mild, such as some cases of the common cold (among other possible causes, predominantly rhinoviruses), though rarer forms can be lethal, such as SARS, MERS, and COVID-19. Experts welcomed the findings but cautioned the antibody is not yet close to being harnessed against the new virus which is thought to have first started spreading from a wholesale food market in the central Chinese city of Wuhan, Hubei province, in December 2019. S. nationals stranded aboard the cruise ship Diamond Princess, which had been held in quarantine in Yokohama, Japan.[26] Fourteen of those repatriated people were infected with the virus.[27] Five more nationals who were also reported as being infected were evacuated from the ship the following week, and were quarantined at an air base in California. Some animal coronaviruses, such as feline coronavirus (FCoV), may spread through contact with feces. Confirmation of the new cases, from 52 additional test results, brought the total number of infections diagnosed on board the Diamond Princess so far to 634, the ministry said in a statement. — Agence France-Presse 6:05 AM / February 20, 2020 South Korea reports first coronavirus death South Korea reported its first death from the new coronavirus on Thursday while the mayor of a southeastern city urged his 2. Tedros said the name had been chosen to avoid references to a specific geographical location (i.e. The overdue response times of the government has led critics to accuse Abe of "callous indifference in the face of an unfolding disaster" and the government as a whole as being "out of touch with the lives of ordinary people that they seem genuinely uninterested in their plight".[497][498] The strict constraints on testing for the virus by Japanese health authorities have drawn accusations from critics such as Masahiro Kami, a physician and director of the Medical Governance Research Institute, towards Abe of wanting to "downplay the number of infections or patients because of the upcoming Olympics." Reports that only a small select number of public health facilities were authorised to test for the virus, after which the results could only be processed by five government-approved companies, has created a bottleneck where clinics have been forced to turn away even patients who had high fevers.

The more serious cases can lead to severe lung damage. The scale of an outbreak depends on how quickly and easily a virus is transmitted from person to person. He also said a research paper suggesting half a million people in the UK could die in the event of a flu pandemic was a “reasonable worst-case scenario.” American Airlines has announced it is suspending flights to and from Milan, Italy from both New York and Miami from March 1, 2020 until April 25, 2020, citing reduced demand. The man went last night to the National Institute of Infectious Diseases Matei Balș with fever but with symptomatology that "does not fit into the case definition of COVID-19." He was nevertheless tested since he had traveled to Italy [source] First 2 cases in the Maldives. Scientists still don't know exactly how the new virus is spread but it does seem to be very infectious. "Tiny droplets from coughs and breathing are most likely," Prof Ball says, so quarantining or isolating those returning from outbreak hotspots is lowering that risk even further. Use a household cleaning spray or wipe to clean all frequently-touched surfaces every day. To date, there is no vaccine and no specific antiviral medicine to prevent or treat COVID-2019. Most coronaviruses spread the same way other cold-causing viruses do: through infected people coughing and sneezing, by touching an infected person's hands or face, or by touching things such as doorknobs that infected people have touched. While the outbreak is a serious public health concern, most people who contract the coronavirus do not become seriously ill, and only a small percentage require intensive care.

Avoid close contact, when possible, with anyone showing symptoms of respiratory illness such as coughing and sneezing. Coronaviruses are enveloped viruses with a positive-sense single-stranded RNA genome and with a nucleocapsid of helical symmetry.

The new restrictions will not apply to transit passengers, Russian state news agency TASS said. Public transport was modified,[261][259] and museums throughout China were temporarily closed.[262][263] Some experts doubted the accuracy of the number of cases reported by the Chinese government, which repeatedly changed how it counted coronavirus cases.[264][265][266] Infrared cameras were installed in Wuhan railway station to check passengers' body temperature before they board the trains. Muscle pain, sputum production and sore throat are some of the less common symptoms.[3][10] While the majority of cases result in mild symptoms,[11] some progress to pneumonia and multi-organ failure.[8][12] The case fatality rate is estimated at between 1% and 5% but varies by age and other health conditions.[13][14][15] The infection is spread from one person to others via respiratory droplets, often produced during coughing.[16][17] Time from exposure to onset of symptoms is generally between 2 and 14 days, with an average of 5 days.[18][19][20] The standard method of diagnosis is by reverse transcription polymerase chain reaction (rRT-PCR) from a nasopharyngeal swab or sputum sample. For example, the DNA from the recombining virus from step (iv) may be inserted into a plasmid and used to transfect cells which express cytoplasmic T7 RNA polymerase.

Although anyone of any age can get it, only one in five of the population will probably be infected.

This brought the total confirmed US deaths due to coronavirus to 19, 16 in Washington, 1 in California, and 2 in Florida. The genome size of coronaviruses ranges from approximately 27 to 34 kilobases, the largest among known RNA viruses.[7] The name coronavirus is derived from the Latin corona, meaning "crown" or "halo", which refers to the characteristic appearance reminiscent of a crown or a solar corona around the virions (virus particles) when viewed under two-dimensional transmission electron microscopy, due to the surface covering in club-shaped protein spikes. Face masks with respiratory valves are more effective than regular paper surgical masks, and cloth masks may do more harm than good. SARS was severe but didn’t transmit easily between people, which helped health officials contain the outbreak. This virus can spread, and it can be deadly,” said Haseltine, who headed research on an anthrax antidote. “We’ve prepared for bioterrorism in general.
