Symptoms of Coronavirus 2019 – COVID-19

Patients with COVID-19 have experienced mild to severe respiratory illness.,Fever Cough Symptoms may appear 2-14 days after exposure.,Seek medical advice if you develop symptoms and have been in close contact with a person,known to have COVID-19.,Or if you live in or have recently been in an area with ongoing spread of COVID-19.,

details about  new,chrono virus from Wuhan China otherwise,known as 2019 and CoV in the system we,talk about the incubation period for,this virus signs and symptoms some risk,factors also talked about how we can,make the diagnosis of this virus and we,talked about possible treatments and,preventative measures so the 2019 n Co V,stands for 2018 novel coronavirus and,this is the virus that was recently,discovered in Wuhan China it is a beta,corona virus it’s actually the seventh,Crona virus found to cause illness in,humans unlike other corona viruses it,can cause respiratory and,gastrointestinal infections due to its,ability to bind to respiratory and,gastrointestinal cells with its viral,proteins and it can lead to a variable,clinical picture it can have variable,respiratory and possible,gastrointestinal symptoms we talk about,in this lesson so when a patient gets in,contact with this virus there is an,incubation period it takes what we,believe to be anywhere from 2 to 14 days,following exposure so after getting,exposed to the virus it takes,approximately 2 to 14 days to experience,symptoms and become ill with it and as I,mentioned before it can have a variable,clinical presentation so in some,instances patients can have this virus,and be asymptomatic that can have no,symptoms they can have maybe some mild,symptoms and it can even go up to severe,illness and even mortality and what,seems to be the case from what we see in,our evidence now is that older,individuals adults greater than 40 to 50,years of age being male and having,pre-existing comorbidities can be risk,factors for contracting this virus and,having worse clinical presentation so,more severe illness so what are some of,the common symptoms of having this virus,so there is some evidence that has been,shown in The Lancet and other journals,that some of the common symptoms include,fever so fever is actually the most,common finding we see so individuals,with this virus seem to almost always,have fever if they present,symptomatically the next one is coughed,and the cough can either be,non-productive or productive which means,that there can,be sputum or can be a dry cough this is,the second most common symptom and it’s,more often to be a dry cough or,non-productive cough then to be a,productive cough so if we see symptoms,those are the two most common symptoms,another common symptom is shortness of,breath so shortness of breath can be a,common symptom as well difficulty,breathing is another common symptom we,can also see malaise and fatigue so,being very tired having very little,energy can be common symptoms as well,what are some other symptoms less common,symptoms these include myalgias so achy,muscles we can also see headaches these,are more rare we may also see confusion,sore throat and rhinorrhea or a runny,nose and again these seem to be less,common symptoms we can also see,gastrointestinal symptoms we mentioned,before that coronaviruses can cause,gastrointestinal infections and we can,actually see diarrhea and possibly,nausea and vomiting with the corona,virus this is again extremely rare there,seems to be one percent or less patients,having this so right now it seems that,the common symptoms I talked about in,the previous slide occur in the majority,of cases fever cough shortness of breath,so these other symptoms again are very,rare especially the gastrointestinal,symptoms and it seems that approximately,20% of individuals who contract this,virus have a critical presentation they,become very ill this can include a very,bad pneumonia renal failure so kidney,failure,acute respiratory distress syndrome or a,RDS and death and this can occur,infrequently but it can occur in,approximately 2 to 3 percent of cases,and it’s normally due to a multiple,organ failure so again these more,critical illnesses and having more,symptoms in general seem to occur in,older individuals who are particularly,male for some reason and who have,underlying comorbidities so those are,the risk factors for having a worse,presentation so we’re now going to talk,about laboratory and imaging findings so,some of the laboratory findings in,individuals with this virus include the,following neutrophilia so increased,neutrophil counts lymphopenia so,decreased lymphocyte counts thrown,saito Pina trans-am and itís so transom,and itis is essentially having increased,alt and ast levels those are enzymes in,the liver so this seems to cause a,little bit of liver injury as well and,increased LDH now with regards to,imaging findings this is a very,important one to note so if we were to,take a chest x-ray of an individual who,does happen to have this virus and has,pneumonia,it seems the majority of the time be,bilateral and this is very uncommon so,it’s a bilateral pulmonary infiltrates,that are seen on chest x-ray this is the,majority of patients who have 2019 and,COV pneumonia and if we look at a CT,scan these individuals might have,ground-glass opacities and these two,seem to be bilateral so these are,occurring in a minority of cases again,it’s mostly the bilateral pulmonary,infiltrates we see we can see unilateral,pulmonary infiltrates but we can also,see ground-glass opacities on a CT scan,and with the CT scan you may also see,multi lowbar consolidations so here is,an image showing bilateral or,multilateral pulmonary infiltrates on,imaging with regards to this 2019 and,CoV so how do I make the diagnosis and,are there any possible treatments for,this virus so the way we diagnose it is,through detecting the viral genome by,real-time qPCR so this is the way we can,detect the virus and make an affirmative,diagnosis once we make the diagnosis are,there any ways we can treat it right now,there are no official treatments,available there has been nothing shown,through evidence to say this is a,treatment that we can use so right now,we are using supportive care so giving,patients fluids treating any Co,infections or any bacterial,co-infections with antibiotics those,types of treatments so it’s more,supportive at this point there is one,report from Thailand of physicians using,also Tama vir so also Tama vir is an,anti influenza antiviral and they used,also time of year in combination with,lopen aveer in ritonavir and they seem,to have shown at least in one patient,that the crown virus was negative within,48 hours,so this is very anecdotal at this point,it’s only one patient but it’s a,possible step forward with regards to,determining a treatment for this virus,so also time of year again is an,antiviral we use for influenza and lo,pin of ear and right on of ear are both,antivirals that we use to treat HIV so,right now we’re in early stages of,determining a treatment but this may be,a right step forward so how do we,prevent getting infected with this virus,in the first place so if we feel that we,may have been in contact with someone,that is sick or we’ve touched something,that another person might have touched,our hands are dirty we want to wash,hands with soap and water for at least,20 seconds we could use an alcohol-based,sanitizer instead if soap and water are,unavailable we want to avoid close,contact with sick patients or dead or,living animals so we want to avoid close,contact close contact is defined as 2,meters or 6 feet so a 2 meter or 6 feet,radius we also want to avoid travel to,affected areas so any areas that are,having any outbreaks of any virus we,want to try to avoid travel to those,areas if you are sick or are ill,possibly with this virus you want to,avoid going to work or work places you,want to avoid infecting others in,important as part of all of this is what,we call respiratory hygiene respiratory,hygiene is where we want to avoid,touching our mouth nose eyes face if our,hands are not washed,so if we have dirty hands you want to,avoid touching your mouth nose eyes and,face unless you have already washed your,hands so this is common with all viruses,all illnesses but this is important for,preventing this virus as well and,there’s this question of using a face,mask right now w-h-o doesn’t seem to,highly recommend a face mask so right,now the w-h-o is suggesting that you,might not need a face mask if you are,asymptomatic you’re around other people,that are asymptomatic and you’re not in,an area where there is a lot of this,virus so it might just be an unneeded,financial cost so we’ll kind of keep an,eye out,for further information on face masks,and if you or someone else is sick and,they’re coming back from a area that has,this viral outbreak the Centers for,Disease Control,in the United States suggest quarantine,for 14 days that is the incubation,period for this fire so this is what,we’re doing right now,so again if you’re arriving from an area,of outbreak and if you are symptomatic,or asymptomatic so they wait to see the,incubation period and see if you require,quarantine or require treatment so again,these are the ways to help prevent this,new corona virus wash hands with soap,and water for at least 20 seconds if,your hands are dirty can use an,alcohol-based sanitizer instead if,needed avoid close contact with sick,individuals maintain a approximately two,meter or six feet radius avoid travel to,affected areas avoid school in,workplaces if you are sick or ill and,maintain good respiratory hygiene these,methods help prevent all sorts of,illnesses especially respiratory,illnesses not just this new corona virus,so again these are methods we can use to,help prevent this new corona virus in my,other lesson on this corona virus I,talked about the ways that it is,transmitted it’s transmitted through,several different mechanisms so please,check out that lesson for more,information on transmission and if you,want to learn more about other,infectious diseases please check my,infectious disease playlist and if
