If a mosquito bite persists in being red and itchy two weeks after the fact (but it then recedes certainly by a week after that), is that a precursor to (or sign of) a mosquito-borne disease like dengue, malaria, or West Nile?

To put it conversely: The mosquito bites that lead to dengue, malaria, West Nile, etc. - are they normal (i.e. red and itchy for a few days only)? Are they abnormal (i.e. persistent red and itchy for at least 2-3 weeks)? Or both?

I'm asking this because a) I had a mosquito bite almost four weeks ago and it was persistent even two weeks later (though it receded a week after that), and b) I was sick with 102F fever (including sweats and chills), headache, and aches on some parts of my body especially late last week and well into the weekend (and I went to the doctor earlier this week and it was some unidentified viral infection). (Now I'm almost fully recovered.)

No. The itchiness is a histamine reaction to the anticoagulant the mosquito injects. It's possible you are more sensitive and had a bigger reaction to it or you happened to get a bigger than normal dose of the anticoagulant in that bite. It's possible it wasn't a mosquito bite at all. Could have been a biting fly (red devil, black fly, white socks, no-see-ems are a few I know of farther north like CA and AK where I live). I've had bites from those that lasted that long. I've noticed that different bites vary as far as the reaction. Different areas of the skin can have more or less of a histamine reaction. Every time you scratch the bite it sort of re-triggers the reaction too. These days I apply heat to a bite as soon as I can. It helps disrupt the histamine production reaction.

The diseases you list are viral. Symptoms of them are more severe than those you described. What you had could just as easily be picked up from the general population. Were you in Montreal when bitten or were you traveling abroad? Shouldn't be any of these diseases that far north yet.

Actually, Dengue is in the US, (not trying to out-do you Ms. Heron, but I live in the tropics!) as well as Malaria and West Nile.

And don't forget Zika virus. South Florida got it in the last couple of years.

https://www.cdc.gov/zika/reporting/case-counts.html

OP, personally I would have some blood tests run by my Dr. if mosquito bite is still persisting after a few days. The 102 degree fever didn't sound good either...Just to be on the safe side, I'd have it looked into.

I was in Montreal the whole time. And yes, it is true that generally symptoms are more severe, but for West Nile without neurological/encephalitic complications, symptoms are generally mild and last a few days (kind of similar to what I had a week ago).

And it sounds like, in general, that there's no real correlation between the nature of the mosquito bite and coming down with a mosquito-borne disease?

Alternatively, it might be some other viral flu-like illness, as during my recovery period I developed a few coughs here and there (not really strong ones, though).

Check your local health department updates for your county. They'll list how many cases of which disease is impacting the area. If your area is known for certain disease related illnesses, they'll list them. Here is a map of Harris County (Houston) from their county health department page. Areas in yellow are impacted by mosquitos.

Did you see the mosquito? Could be a chigger. Itches like hell for 7-10 days.
