How long can the new coronavirus live on a surface, like say, a door handle, after someone infected touches it with dirty fingers? A study out this week finds that the virus can survive on hard surfaces such as plastic and stainless steel for up to 72 hours and on cardboard for up to 24 hours . . .

 . . . And given that wipes are hard to come by at many stores at the moment, you can instead buy an EPA-registered disinfecting spray, such as one on this list from the Center for Biocide Chemistries, recommended by the Centers for Disease Control and Prevention and by Dr. David Warren, an infectious disease specialist at Washington University School of Medicine in St. Louis.

Or make a bleach-based spray yourself. You can make a DIY cleaning spray by mixing 4 teaspoons bleach per quart of water, according to the CDC.

Older adults and people who have severe chronic medical conditions like heart, lung or kidney disease seem to be at higher risk for more serious COVID-19 illness. Early data suggest older people are twice as likely to have serious COVID-19 illness.  This may be because:

    As people age, their immune systems change, making it harder for their body to fight off diseases and infection.
    Many older adults are also more likely to have underlying health conditions that make it harder to cope with and recover from illness.

If a COVID-19 outbreak happens in your community, it could last for a long time. Depending on the severity of the outbreak, public health officials may recommend community actions to reduce exposures to COVID-19. These actions can slow the spread and reduce the impact of disease.

If you are at increased risk for COVID-19 complications due to age or because you have a severe underlying medical condition, it is especially important for you to take actions to reduce your risk of exposure.

Quote from Dr Tedros Adhanom Ghebreyesus, Director-General of the World Health Organization:

"This is airborne, corona is airborne, it's more contagious and you have seen how it went into 24 countries although it's a small number of cases."
