targetmle yes because i thought they wont give ques on current coronavirus situation so early!! +

adamventure I thought to myself "damn it sure would be fuckin hilarious if Coronavirus was the answer".. turns out it was and it wasn't hilarious since I got it wrong. +67

asdfjkl no quotes needed for pandemic anymore :( big sad +14

yesa Yes! but also, coronaviruses often cause the common cold, not all of them are really bad! So this 4yo girl could literally just have the common cold, and the coronavirus isolated from her likely doesn't have pandemic potential. So this question has nothing to do with the ongoing pandemic--it's just coincidence! +2

jaramaiha Was I the only one that thought it was cause it is enveloped and easily destroyed? lol I didn't even bother with descriptors. +1

zelderonmorningstar EBV doesn’t cause fever and cough? +1

zelderonmorningstar Wow, just checked First Aid and it doesn’t list “cough” as a symptom of EBV. +4

drdoom EBV is not a “respiratory virus”; it’s a *B cell virus*. Even though you might associate it with the “upper respiratory tract” (=kissing disease), it doesn’t cause respiratory inflammation since that’s not its trope. B cells are its trope! That’s why EBV is implicated in Burkitt Lymphoma, hairy leukoplakia and other blood cancers. (EBV is also known as “lymphocryptovirus” -- it was originally discovered “hiding” in *lymphocytes* of monkeys.) So, EBV = think B cells. +30

fulminant_life EBV does cause pharyngeal and laryngeal inflammation along with fever, malaise, and cough and LAD. The only thing that pointed me away from mono and towards coronavirus was the patients age. +8

nbmehelp Can someone explain what not holding up to acid or being dried has to do with being enveloped? +

yb_26 @nbmehelp, the envelope consists of phospholipids and glycoproteins => heat, acid, detergents, drying - all of that can dissolve the lipid bilayer membranes => viruses will loss their infectivity (because they need an envelope for two reasons - to protect them against host immune system, and to attach to host cells surface in order to infect them) +12

lowyield @yb_26 does that mean that non-enveloped viruses hold up better to acid/dryness? +2

rina yes enveloped viruses are easier to kill (see post from drsquarepants: https://www.nbmeanswers.com/exam/nbme23/1161). also i think the "when dried" might refer to the fact that coronavirus is spread by respiratory droplets (don't even need to read first aid can just read the news at this point!) +4

hello ...COVID-19 is transmitted via respiratory droplets. +4

123ojm Right but some research has come out saying it's also spread fecal-orally. So I'm wondering what I'm missing in this question. +

tyrionwill Don't trust US CDC in this pandemic. They always downplayed the truth. Cronavirus does spread mainly by droplets, when they drop, they contaminate the surface, then fecal-oral could be a second pathway. Wearing mask, social distancing are both to prevent a droplet. +

boostcap23 I thought covid used to be low yield when this test was made and they didn't mention helical so I didn't pick it smh I'm an idiot. +1
