Yellow fever is a highly dangerous disease that kills about 30,000 people per year across the globe. 15% of those who contract the disease face the risk of internal bleeding and kidney damage. Considering that every year, almost 200,000 people are infected with the disease, a significant portion of the world’s population faces these severe risks. These risks are amplified and the risk of mortality is high for those who contract yellow fever because there is no treatment for the disease – only supportive care can be provided.
The best way to prevent getting yellow fever is to get vaccinated in your home country before travelling to an area where the disease is present. Along with the vaccine, you will get a certificate from your clinic stating that you have been immunized. Clari Health stocks the yellow fever vaccine and we can offer you same-day appointments so that you can get your jab and certificate as soon as possible.
In the USA, all foreign nationals and US Citizens, aged nine months and above, who have been in or passed through any country at risk of yellow fever six days before arriving in the USA, are required to have a valid International Certificate of Vaccination for yellow fever and present it to the Immigrations and Checkpoints Authority (ICA) officer at the point of seeking immigration clearance.
- When to get vaccinated: Consider a minimum of 10 days before your trip to get the vaccine. The certificate you receive will not be valid before these 10 days have gone by.
- Where to get the yellow fever vaccine in Seattle and Bellevue: The yellow fever vaccine is only available at registered yellow fever vaccination centres, such as travel health clinics and general practice clinics. Our travel clinics in Seattle and Bellevue are designated Yellow Fever Vaccination Centers by the CDC. At our clinics, you will receive a Yellow Fever Vaccine Certificate as proof of immunization.
- How long it lasts: Once you’re vaccinated, you are protected for life. In very rare cases, you will need a booster dose to renew your certificate.
- Vaccine dosage: Most people only need one dose in the course of a lifetime.

Adults and infants from nine months of age travelling to an area where yellow fever is found or a country that requires a certificate proving you’ve been vaccinated against yellow fever should get the jab at least 10 days before their trip.

- Between 6 and 8 months old

What is yellow fever?
Yellow Fever is a deadly viral infection that is transmitted by mosquitoes found in sub-Saharan Africa, Central and tropical South America, and the Caribbean. This disease is not curable as there is still no treatment for it, but it can be prevented by getting a vaccine.
As stated by the CDC, certain regions and countries where yellow fever is common will require all travelers to get vaccinated before visiting and to show a certificate of vaccination at the entrance border. The CDC also requires those who have been to countries with a risk of transmission for yellow fever six days before arriving in the USA to show proof of Yellow Fever vaccination.
However, bear in mind that even when a country has no requirement for yellow fever vaccination there still could be a risk of yellow fever transmission.
What are the symptoms of yellow fever?
The first symptoms of yellow fever usually appear three to six days after infection. In most mild cases, yellow fever symptoms can include headaches, fever, nausea and vomiting. A loss of appetite, muscle pain and backache, and light sensitivity can also develop along the first symptoms. Fatal heart, liver and kidney conditions are found in the majority of the most serious cases, however, most people see a recovery after three or four days of treatment.
In the worst cases fatal symptoms such as jaundice (the yellowing of the skin and eyes), bleeding from the mouth, eyes or nose, and vomiting or excreting blood could appear. Almost 50% of patients presenting these symptoms do not recover.
Transmission
The yellow fever virus is transmitted by the bite of an infected female mosquito that inhabits tropical and subtropical parts of the world. The mosquito acquires the virus by feeding on an infected primate (monkeys or humans) and is usually active between sunrise and sunset. You will not get yellow fever by having direct contact with an infected person.
Where is yellow fever found?
Yellow fever has been reported to have infected both humans and monkeys in the following regions:
- Central America
- The Caribbean
- Most of South America
- Most of Sub-Saharan Africa

Is yellow fever curable?
There is currently no cure available for yellow fever. However, it can be prevented by getting a vaccine against it or avoiding mosquito bites.
How can you prevent yellow fever?
Even if you’ve been vaccinated against it, if you’re travelling to a country or area where yellow fever is present it’s best to avoid being bitten by an infected mosquito that could also spread diseases like malaria or dengue. Take extra care by wearing long-sleeved shirts and pants, using repellent-sprayed mosquito nets to sleep, and spraying insect repellent regularly during the day.
How to prevent mosquito bites?
- Use insect repellent: If you are also using sunscreen, apply sunscreen first and insect repellent second.
- Protect your child:
- Dress them in clothing that covers their arms and legs
- Wear long-sleeved shirts and long pants
- Buy a bed net that you can carry with you: It should be long enough to tuck under the mattress
- Stop mosquitoes from going indoors:
- Use mosquito nets/screens on windows and doors
- Prevent mosquitoes from laying eggs:
- Items that hold water, such as buckets, pools, birdbaths, trash containers, tires, planters, flower pots or toys need to be emptied and scrubbed, turned over or covered
