Yellow fever first appeared or originated in Africa, caused by a virus of the Flavivirus genus, which belongs to the Flaviviridae family. The virus is usually transmitted to wild monkeys by primatophilic Aedes mosquitoes. It entered the slave trade era in Western countries. In Yucatan in 1648, the disease became an epidemic for the first time.
Yellow Fever Vaccination Appointment
This viral disease was an epidemic for the next 200 years. In 1886, a Cuban physician named Carlos Finlay first identified the Aedes aegypti mosquito as the exact cause of yellow fever disease. Different names know this disease in regions like bronze john, yellow jack, yellow plague, etc. Currently, 40% to 50% of people in Africa are seen to reach a serious condition due to this disease. In addition, 90% of people in tropical and subtropical areas of Africa and South America are affected by this disease every year.
Currently, the annual number of people seriously affected by it worldwide is about 15%. Although this disease can now be removed through proper diagnosis, the number of deaths remains stable. However, this disease is believed to be eradicated by specific vaccinations. This article comprehensively explains this disease’s symptoms, effects, risks, treatment, and vaccination methods.

Definition and description of Yellow Fever
Yellow fever is a hemorrhagic disease mainly carried by mosquitoes. A person becomes infected with yellow fever through the bite of a mosquito that carries the yellow fever virus. Symptoms of this disease may take up to three to four days to appear in the affected person. The disease does not flow from the entire human body to the upper human body. That is, it is not a contagious disease. Rather, a person infected with yellow fever is bitten by an Aedes mosquito, and the virus is transmitted if that mosquito comes into contact with a healthy person.
Discovered in the US in the 17th century, this disease is now almost eradicated, but the number of people affected by it has not been reduced to zero. Although this disease has lost its epidemic form, it is still active in coastal areas of Europe, Asia, South America, and tropical areas of Africa. At this stage, proper uptake of yellow fever vaccination is essential to combat this disease which has been active for over 400 years. Only through proper vaccination can this much-discussed disease be eradicated.
Effects of Yellow Fever on the human body
The disease mainly flows through three stages: jungle, intermediate, and urban. In the jungle stage, the disease virus is transmitted between non-human bodies. In this case, the virus flow by mosquitoes among the monkeys in the forest is significant.
In its later stages, the flow of the Roger virus from the monkey body to the mosquito and from the mosquito body to the human body in the wild can be seen. In the next and final stage, the flow and invasion of the virus from the human body in the jungle to the mosquito body and from there to the human body in civilized society are observed. The main symptoms of this disease are fever, vomiting, chills, and severe headache.
In many cases, their severity is seen as blood vomiting and organ failure. Yellow fever vaccination must be applied at an early stage to prevent the severity of this disease. Timely application of vaccination prevents the spread of the disease and ensures the development of the individual’s immune system.
Symptoms and stages of Yellow fever
Multiple types of yellow fever symptoms can be observed in the human body. In this case, fever, nausea, and severe headache frequently occur as symptoms of this disease at the primary level within two days of infection. In the next 3 to 4 days, the disease virus develops fully.
In this case, the symptoms are onset fever, vomiting, weakness, chills, muscle pain, fatigue, back pain, etc. The highest severe symptoms of this disease are usually seen in one in seven people. Symptoms of this highest severity include jaundice, organ failure, high fever, shock, and bleeding.
In this case, the yellow fever virus usually attacks specific organs such as the kidneys and liver, resulting in kidney or liver failure in patients with the highest stage of yellow fever. One of the severe symptoms of this disease is jaundice, in which the patient’s skin and eyes turn yellow. Mainly because of this, the name of the disease was yellow fever.
How do vaccines cover it?
The yellow fever vaccine easily prepares the human body to deal with yellow fever. In this case, it is possible to get lifetime relief through a specific dose. However, in many cases, some people must take multiple doses every ten years. The yellow fever vaccine causes the human body to produce its own antibodies so that it is able to deal with the yellow fever virus at certain times.
In this case, it is necessary to arrange vaccination of certain doses at the appropriate time in the areas where the outbreak of yellow fever is clearly visible, especially in those areas. In addition, to ensure this disease’s elimination, local residents of urban areas located near tropical and semitropical areas must also be covered under specific sustainable vaccination coverage.
How to get rid of vaccine
Through vaccination, a person can acquire the ability to easily suppress yellow fever because yellow fever vaccination produces appropriate antibodies in the human body. Lifetime immunity from yellow fever is usually achieved with a single dose.
However, people who normally travel to yellow fever risk areas are advised to get a booster dose of this vaccine every ten years. The yellow fever vaccine is universally the same for persons aged 9 to 60 years. Also, pregnant women are not usually given the vaccine unless they live close to or travel to a yellow fever-affected area.
How to get an appointment for the vaccine
Generally, through the initiative of local government health centers, area-based vaccination camps are organized to educate people about yellow fever vaccination and information on how to take the vaccine. One can collect information about his nearest yellow fever vaccination center and book an appointment from the Ministry of Health and Welfare website or mohawk.
Also, information about age and stage-appropriate vaccinations can be found on the WHO official page. Apart from this, a resident of India or an international traveler can book an appointment for certain vaccinations through the VAT online portal in India.
For Indian citizens, vaccinations are provided every week on Wednesdays and Saturdays at designated vaccination centers for just Rs.300, but the vaccination fee varies from place to place. In this case, the person receiving the vaccine from the specific vaccination center receives the vaccination certificate within the specified time, also the person can download the specific vaccination certificate from the TravelHealthPro website or apply for a hard copy after the vaccination.
By reviewing and evaluating all the issues discussed above, it can be concluded that, although the yellow fire is now apparently eradicated, it is still active in several tropical and semitropical areas, resulting in 15% of people worldwide being severely affected by the disease. However, in this case, it is possible to deal with it reliably through specific vaccinations, so it is necessary to motivate people to prioritize yellow fever vaccination through specific vaccination awareness programs and initiatives.
