thanks! this helped break down the differences of symptoms between dengue and zika for me

Hey Dr. Seheult. Not all RNA viruses actually have reverse transcriptase. Reverse transcriptase is almost exclusive to the family of viruses known as retroviruses except for a few special cases. Most RNA viruses will actually just proceed to replicate in the cytoplasm and never make a DNA intermediate. This works in 1 of 2 ways. In the case that a single-stranded RNA virus enters that is considered positive sense. Positive sense RNA mimics cellular mRNA, so it will just use RNA polymerase III to make a negative sense template for making more genomic positive sense. Furthermore, the positive sense serves as a template for making all the viral proteins. In a negative sense case, it's the opposite where the virus will use cellular enzymes to make a template positive sense that will now be recognized to make proteins using cellular ribosomes and have complimentary copies made which are the negative sense genome of that virus.

For Flaviviruses (of which Zika, Dengue, and Yellow Fever viruses belong), they have positivee sense single stranded RNA, so they will follow the former of the two aforementioned scenarios for single stranded RNA viruses. Thank you for making these videos, though. They are great!

i m a medical student
thank you fr getting us updated

[rrfirefly]

Please make an update of this virus as it is present in the U.S. in 2018. This video is over 2 years old.

[jofmatos]

Thank you for the great explanations as always. I'm from Brazil, and that will be very useful for my patients.

FYI, as of this date, South Florida (Miami/Ft. Lauderdale region) is now under emergency ZIKA warning with mosquito awareness and chemical spraying. It is no longer just in the South American regions anymore.

[gagaplex]

Very good overview, especially since you included Dengue and Chikungunya and ways to differentiate!

[zoniazafar]

hey Dr Roger i really love and enjoy your vedios they are amazing to learn from keep up the good work and please come up with some new topics like EEG ECG MRI CT

[nbenitez]

please do an overview of diabetic medications both oral and insulins

[lisagonzalez]

Thanks very much for your video. I've watched some already, and decided to subscribe. I'm a med student living in Dominican Republic, so of course this video is of great use to me. Just yesterday coincidentally I was at a friend's dinner and a family member seemed to be presenting with Zika. It's everywhere in D.R... with MANY people having the G.B. complication...

[ellisb]

This is a very good video, and quite informative as well . Thank you

Since when does the 'Zika Virus' cause Microcephaly? Before 2016 it was a well known mild illness that passed away after a few days.

[IndyD]

Thx, I'm German and I love your videos!

Hi Dr. Seheult. I have one question concerning the diagnosis of zika virus through serology. Recently I read an article in the New England journal of medicine saying that they don't have sufficiently specific detection methods and that there are quite a lot of cross reactions. Which means that in a lot of cases it remains unclear whether the patient contracted dengue or zika. What is your comment on this? Thank you! :)
