COPPER KILLER
that copper surfaces tended to kill the virus in about four hours.
DROPLETS:
Like many respiratory viruses, including flu, Covid-19 can be spread in tiny droplets released from the nose and mouth of an infected person as they cough. A single cough can produce up to 3,000 droplets. These particles can land on other people, clothing and surfaces around them, but some of the smaller particles can remain in the air. There is also some evidence that the virus is also shed for longer in faecal matter, so anyone not washing their hands thoroughly after visiting the toilet could contaminate anything they touch.
Although there is no data on how many virus particles will be in a single droplet coughed up by an infected person, research on the flu virus suggests smaller droplets can contain many tens of thousands of copies of the influenza virus. However, this can vary depending on the virus itself, where in the respiratory tract it is found and at what stage in the infection the person is.
SIZE:
shows that the virus could survive in droplets for up to three hours after being coughed out into the air. Fine droplets between 1-5 micrometres in size – about 30 times smaller than the width of a human hair – can remain airborne for several hours in still air.
BLEACH
But there is a speedier option: research has shown that coronaviruses can be inactivated within a minute by disinfecting surfaces with 62-71% alcohol, or 0.5% hydrogen peroxide bleach or household bleach containing 0.1% sodium hypochlorite. Higher temperatures and humidity also tend to result in other coronaviruses dying quicker, although research has shown that a related coronavirus that causes Sars could be killed by temperatures above 56°C or 132°F (hotter than even a bath scalding enough to cause injury) at a rate of about 10,000 viral particles every 15 minutes.
HOW LONG ON SURFACE
up to 24 hours on cardboard and up to two to three days on plastic and stainless steel.
But the NIH study found that the SARS-CoV-2 virus survives for longer on cardboard – up to 24 hours – and up to 2-3 days on plastic and stainless-steel surfaces.
Previously published studies have indicated coronaviruses in general — not specifically the new one — can last up to nine days on surfaces depending on the surface type, the heat, the humidity, exposure to sunlight and other factors, said Joseph Fair, a virologist,
TOUCHING FACE:
It is worth noting that, according to the Centers for Disease Control and Prevention, touching a surface or object with the virus and then touching one's own face "is not thought to be the main way the virus spreads". Even so, the CDC, the World Health Organization and others health authorities, have emphasised that both washing one's hands and cleaning and disinfecting frequently touched surfaces daily are key in preventing Covid-19's spread. So although we still don't know exactly how many cases are being caused directly by contaminated surfaces, experts advise exercising caution.
INCUBATION PERIOD SYMPTOMS:
Most people who develop COVID-19 start noticing symptoms within 2 to 14 days after being exposed to the novel coronavirus known as SARS-CoV-2. On average, it takes about 5 days to develop symptoms, but this may change as we learn more about the virus.

the incubation period for the novel coronavirus is somewhere between 2 to 14 days after exposure.
According to a recent report
Trusted Source
, more than 97 percent of people who contract SARS-CoV-2 show symptoms within 11.5 days of exposure. The average incubation period seems to be around 5 days. However, this estimate may change as we learn more about the virus.
For many people, COVID-19 symptoms start as mild symptoms and gradually get worse over a few days.

Is it compulsory to wear face masks in China?
Since the outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that caused coronavirus disease 2019 (COVID-19), the use of face masks has become ubiquitous in China and other Asian countries such as South Korea and Japan.
MASKS ARE SUPER IMPORTANT BUT PLAYED DOWN BY THE FOOLISH
Some provinces and municipalities in China have enforced compulsory face mask policies in public areas; however, China's national guideline has adopted a risk-based approach in offering recommendations for using face masks among health-care workers and the general public. We compared face mask use recommendations by different health authorities (panel). Despite the consistency in the recommendation that symptomatic individuals and those in health-care settings should use face masks, discrepancies were observed in the general public and community settings.1, 2, 3, 4, 5, 6, 7, 8 For example, the
US Surgeon General advised against buying masks for use by healthy people. One important reason to discourage widespread use of face masks is to preserve limited supplies for professional use in health-care settings. Universal face mask use in the community has also been discouraged with the argument that face masks provide no effective protection against coronavirus infection.
