Well, this injection is not much fun, so you definitely want to get it notated correctly on your shot record.
Many countries in Sub-Saharan Africa where yellow fever is present require the vaccine. I don't think Kenya requires it, but you should check with the Kenyan embassy. However, even if it isn't required for entry to the country, it is possible that it is highly recommended, so you should also check with the CDC or WHO about which vaccines you should get before traveling to Kenya.
Yellow Fever has been seen as a dangerous disease from as far back as the 17th century. It was probably at its most prevalent in the 19th century with a major epidemic. It is still reckoned to effect up to 200,000 people a year today even with vaccinations.
anyone who isn't immune to yellow fever or hasn't received a vaccination is susceptible to yellow fever if bitten by a mosquito that has bitten a monkey or person carrying the virus. there was a massive yellow fever epidemic in 1793 in Philadelphia where over 5,000 people died and were thrown into ditches so that it wouldn't be spread around. Then another one in Memphis in 1878 though not limited to those two cities. it is found all over the world and is responsible for 30,000 deaths annually in unvaccinated regions.
The number of countries in which a person (and some other animals) can get Yellow Fever is increasing. To find out if there is an exposure risk in a country or region of a country, check the CIA Report for the country in question

Due to the fact that it does not transmit directly from person to person. It transmits via vectors such as the mosquito. These mosquitoes live near the equator where there are tropical weather conditions. Therefore, this disease is unable to spread throughout the world at dangerous and fatal rates.
Yellow fever is a disease spread by the bite of a female mosquito. The virus that causes Yellow Fever is an RNA virus of the genus Flavivirus.
humans didnt have writen records when yellow fever was first dicovered
There are a few different age groups that Yellow Fever affected the most. Yellow Fever tended to affect young children, elderly, and those with a compromised immune system the most.
Yellow fever, also known as the American Plague or Black Vomit, belongs to a family called "Flaviviridae" as a single stranded RNA virus.
Yellow Fever is a viral disease transmitted by the bite of mosquitoes. A mosquito must first bit someone with the disease then come back and bite someone else.
The virus enters the body in the mosquitoes saliva.
Viruses work by entering a cell and taking over the function of the cell's nucleus, causing the cell to make multiple copies of themselves. These then burst out and go on to take over other cells. This process continues until the infected person dies OR until the persons immune system recognizes the virus and develops antibodies that surround and destroy the viruses so that they can no longer get to new cells.
The virus particularly targets liver cells and this causes liver damage which results in the jaundice (yellow color) of the affected person.
the filtering you may be referring to is filtering in search of bacterium which can be "caught in filters". however since yellow fever is a virus it is too small to be caught in the nets and thus can be passed on through blood to another person.
From Wikipedia:
"Most cases only cause a mild infection with fever, headache, chills, back pain, loss of appetite, nausea, and vomiting. In these cases the infection lasts only three to four days. In fifteen percent of cases, however, sufferers enter a second, toxic phase of the disease with recurring fever, this time accompanied by jaundice due to liver damage, as well as abdominal pain. Bleeding in the mouth, the eyes, and the gastrointestinal tract will cause vomitus containing blood. The toxic phase is fatal in approximately 20% of cases. In severe cases the mortality may exceed 50%."
yphoid fever and malaria are caused by parasites; typhoid fever comes about after contact with Salmonella typhi bacteria. The symptoms of both these diseases also do vary to a certain extent. Mostly, a malaria infection will manifest itself through chills, fevers, nausea, vomiting and sometimes even diarrhoea. However, the symptoms of typhoid are stomach pain, skin rashes, extreme muscle weakness and fatigue along with high fever.
A simple blood test (CBC) is enough to decide whether the person is suffering from malarial infection or not. However, in order to detect the presence of salmonella typhi widal test and typhidot are conducted.
Flu vaccines work to give a pattern of the strain of virus they are developed to combat to the body's immune system so it can create a way to disable the specific virus. It works on the principle that once a person has had and survived a virus infection, there is an immunity from the same virus making you ill in the future because the body knows just what to do to stop it the second time before it has any chance of making you sick.
To give the pattern to the immune system, vaccines are made two different ways, one is to use an inactivated form of the virus ("dead" virus) so it can not make you sick but your body will still recognize it as a foreign substance that has invaded your body and it will create the perfect "killer cells" for it. The other type of vaccine is made from active ("live") viruses and it does the same thing with your immune system, except it has been attenuated (weakened) so that it is not strong enough when it gets into your cells to make you sick. See the related questions below for more information.
Another answer:
The vaccine is made from the virus itself! You put the virus into you so your cells notice that it is bad! The cells will 'defeat' the vaccine (or virus), then if you may get the actual virus, the blood cells will know how to battle it and destroy it before it causes harm to your body!

Yellow fever is commonly found in tropical areas. The United States eradicated it by getting rid of mosquito breeding areas and putting screens on houses in the places it existed.

Yellow fever has that name because about 15% of the cases progress to a toxic phase including liver damage and jaundice. Jaundice causes the skin to turn yellow, hence the name.
Benjamin Rush was a great and selfless man who actually treated patients with yellow fever in 1793. He was a physician who lived in Philadelphia. When the there was a yellow fever epidemic in Philadelphia he worked tirelessly to care for patients and to prevent spread of the disease. He also kept detailed records of what he found out from the patients, hoping that his research might help find a cure.
There is no single pill to cure typhoid and yellow fever. You have a pill to cure typhoid but no pill to cure the yellow fever. Yellow fever is a viral infection and there is no specific pill for the same.
