Fever Diseases
Yellow Fever- viral infection
Yellow fever is a viral infection that is passed to humans by day time biting Aedes mosquitoes. It is called this because one of the symptoms is jaundice, which can make the skin and whites of the eyes appear yellow. In the past it was an important tropical disease and epidemics decimated armies and had a huge impact on American ports like Philadelphia, New Orleans and Memphis. Some people call it 'American Plague'.
Yellow fever is what is called an acute viral hemorrhagic disease. The host that is the most common infector is the mosquito, as the other only known host are primates--and we hope not many people are suffering monkey bites in this day and age. The aforementioned symptoms are just the tip of the iceberg as once the disease passes this stage the real problems begin to occur. These changes can be avoided by a yellow fever vaccination.
Yellow fever is a serious disease caused by a virus and prevalent in many Caribbean, African, South and Central American countries. The "yellow" in the name refers to the jaundice-like symptoms that affect some sufferers. Symptoms include fever and flu-like illnesses, jaundice, vomiting blood, liver, kidney, respiratory and other organ failure that can easily lead to death. Yellow fever has been the source of numerous devastating epidemics resulting in catastrophic causalities. One such deadly outbreak happened in 1802 when the disease struck French soldiers during the Haitian Revolution.
Infected individuals suffer fever, chills, headache, muscle aches, nausea and fatigue. This disease gets its name as some people with severe infections develop jaundice, when their eyes and skin turn yellow. All of these symptoms are non-specific, meaning that they can occur in many other diseases also. Many people with this disease may have only a mild illness that can be mistaken for a simple 'flu'. Some people may have no symptoms at all. This disease can progress to a severe illness with life threatening complications. After a person recovers, they are generally immune to the disease.
Yellow fever vaccine is administered for two reasons. The first, and most obvious, is to protect travelers from the infection. Secondly, many countries require travelers to be vaccinated, not for the travelers' health, but to protect their citizens in case you are infected. This requirement is generally enforced if you are traveling from a yellow fever region and are entering a new country. Those who are unvaccinated or have no proof of vaccination can expect to be turned away at the border. While being denied entry on arrival may generate some excitement, this is not our idea of adventure travel!
Travel doctors follow yellow fever disease trends worldwide and can advise you whether a YF vaccination is necessary. Remember, YF vaccine can only be given by a medical professional who has been certified to administer this injection. You will receive an official stamped paper documenting proof of vaccination. Immunity after YF vaccination lasts 10 years. Since the vaccine contains live virus, there are some individuals who should not receive it. Your travel medicine physician will discuss this with you. Ideally, YF vaccine should be administered at least 10 days before arrival to a yellow fever region.
Yellow fever vaccine, a safe and effective live virus vaccine, is administered to millions of people today. This does not make healthy people sick because the virus has been altered so that it cannot cause disease. Side effects are rare.
Yellow fever can be prevented by vaccination. Travelers should also take precautions against mosquito bites when in areas with yellow fever transmission.Travelers should get vaccinated for yellow fever before visiting areas where the disease occurs. In the United States, the vaccine is given only at designated yellow fever vaccination centers.

Swollen armpit lymph node; cat scratch fever: how much longer? (waah.) *fails arms* [long (detailed) post]?
I have a lump under my right armpit which became increasingly uncomfortable/painful over the last month or so, culminating in a visit to my general practitioner (at of the time of this writing my visit was exactly two days ago). Suspecting that it was a swollen lymph node after having had found a bump indicative of cat scratch fever/disease on my wrist on the same side, he has put me on antibiotics (azithromycin), which appears to have diminished the swelling somewhat. Now it appears to have plateaued, though I admit it may still be too early to tell for sure, as the GP informed me the zithro stays in my system for up to ten days or so (I think?) .... so my question(s) is/are:
1. How long will it take for the lymph node to return to normal size (is there a risk that it will stay enlarged, if there is, what are options to reduce the side or get it removed)? The swollen lymph node currently still makes it painful to extend my right arm all the way, especially when reaching up and/or to the right (above shoulder level), I'm guessing because the swollen node gets caught on something near by armpit (I believe there are a lot of veins, arteries and nerves running through there, yes?), thereby necessitating the lymph vessels (I think there are such things) further down my arm to stretch (owww... it hurts just thinking about it).
My primary cause for distress is that it is disruptive to my [physical] yoga practice which I am attempting to make a regular habit, and I am concerned the length of the infection will prevent me from being able to continue participating in any regular classes.
2. This infection has brought to my attention the potential for transmission of parasites and disease from cats to humans as a risk that comes along with the benefits of ownership. I used to give my two [indoor] cats (more like kittens-- approx. 2.5 months old) free reign over my bed, but now feel wary about this, especially letting them on my pillow, since their paws have also been in the litter box which tends to have a lot of poo and pee and worms and icky parasites (they have already had a case of worms, my housemate informs me) and behind my toilet in addition to other less than sanitary areas of my abode.
The thoughts had occurred to me before, but now the worry is much more present in my thoughts after this recent experience. In hindsight, I think my habits used to be quite lax in terms of reducing risk of contracting disease/parasites regarding my pet (i.e. I was bad about not washing my hands after handling/petting my cats, I used rub my face on their fur, etc., but always washed after scooping litter). Now I am always conscious to wash my hands after petting them and turn my face when my cat tries to sniff my face and rub its face against mine (I feel really bad about it though....she is so kewt!) Am I being paranoid??
I tend to leave my bedsheets on my bed (without washing them) for months at a time (sometimes 6, but I try no more than 3), which i realize may exacerbate cleanliness issues. I am inclined to think that more frequent washings of my bedsheets would behoove me. Furthermore, due to my lax habits in the past (the not washing hands and face rubbing and their paws having had been in the litter box then on my pillow where I sleep, etc), should I get tested for parasites or something? Is there even a test that can be done for that sort of thing??
Oh great God of teh internets! I beseech thee for thine wisdom and advice!! What does the hive mind think???
