Some of the questions you've been raising about the corona virus doctor Jenn thank you as always our first question. Ken disinfecting your home multiple times per day. Be harmful to your house is a great question first to can be harmful to your bank account because that's expensive all those cleaning supplies. But potentially if you're inhaling those chemicals if you're getting them on your skin. Absolutely it can be harmful and I think we need to remember the major route of transmission for SARS coat be too. Is the of the respiratory route. Not surface contact so. Clean as you normally would and from which we should be doing all the time but I think don't over clean right where the masks and socially just and perhaps more important are. Next question if someone in your household has come in nineteen. Should you refrain from using the air condition is a hard question because so much of the country is seen nine the or a hundred degree temperatures now in the summer there are no official recommendations on this but what is really important if someone in your household is suspected or confirmed. With coded nineteen. They need to be isolated and they should Wear a mask at home because remember they are a sick person. We don't know yet how HB AC systems can transmit these droplets or aerosol particles so. Distance is important and putting a mask on a person who sickens important OK even while inside they're absolutely. Our next question if someone is been exposed to a confirmed case. When is the best kind to get tested this is a good one this is a really good question I get it all the time you and I have talked about it I'm hearing it from from my patient and doctor found she and I discussed this yesterday. There's no firm date on which you can say wallop I've been exposed how many get tested if I'm negative I'm in the clear. What we do know based on the available evidence is that the average incubation period is five day is. So doctor found she told me if possible you can get tested day 34 or five because there's a pre symptomatic of viral shedding stage. But remember the key if you have had prolonged close contact with a confirmed case. In self quarantine so even if you get that negative result on day five. Wish still should err on the side of caution and keep yourself away from others for fourteen days this all right next question what factors contribute. To how contagious a virus it this is a really important question and there is still a lot that we don't know about this virus there's the infectious dose so how many particles are required. Techniques someone actually sick different viruses have a different fingerprint we don't know what that is yet for SARS Cody to their genetic material it's really. It's a different profile this is an apples to apples apples so every virus has their own fingerprint. Norovirus for example that she got a very contagious extra reliably no picked up the one of the most contagious virus is needles one of the most contagious viruses it doesn't look like stars co V two was in that category yet but they're still studying it in the lab. All right thank you as always actually Jenin you can submit your questions to doctor Jan honor mr. Graham at doctor.
