Stay Away from Mosquitoes and Aware of Yellow Fever

Are you looking forward to exotic travels, having finally found that chance to make your way to South America or Africa? Well, while you’re deciding what to pack for your next adventure, be sure to consider taking the vaccine for yellow fever before you leave.

What’s Yellow Fever?          

It’s important for travelers to central and western Africa as well as parts of Latin America to be knowledgeable of the risks posed by yellow fever. This illness is transmitted by mosquitoes, which acquire a virus from infected primates or humans and then pass it on to others who are bitten. Yellow fever is marked by three types of transmission cycles, and may be acquired in jungle (sylvan), savannah (intermediate), and city (urban) settings.

How can it affect me?

The majority of individuals infected by the yellow fever virus show no symptoms; but each year, many do suffer signs of the illness following an incubation period of three to six days after infection. Affected individuals often experience a sudden fever, chills, intense headache, back pain, body aches, nausea, vomiting, fatigue, and weakness. Once the virus does develop into the illness, the only course of action is to treat symptoms in order to provide comfort, meanwhile allowing the immune system to fight the fever.

Many patients improve after this “acute” phase, which lasts three to four days; but, 15% of patients go on to develop a more severe hemorrhagic fever after an initial remission period of about 24 hours. The high fever characteristic of the illness returns, and now affects multiple body systems. Yellow fever’s victims quickly develop the jaundice for which the virus is named, and may experience abdominal pain as well as vomiting. Bleeding can occur from the mouth, nose, eyes, or stomach, and appears in the vomit and feces. Kidney function deteriorates, and up to half of all patients who enter this toxic phase expire within two weeks.

How can I protect myself?        

Due to the difficulty of diagnosing yellow fever from its initial symptoms, and the potentially dire effects of disease progression, it is absolutely necessary for at risk travelers to protect themselves against the illness. Mosquito repellent is always recommended, but the best course of action is to get the yellow fever vaccination before embarking! The yellow fever vaccine is safe, affordable, and highly effective. A single dose of the vaccine can provide immunity within 30 days, and remains effective for a lifetime without an additional booster shot!

If you are affected by HIV, have primary immune deficiency, or are engaging in an immunosuppressive therapy, it is not appropriate to receive the yellow fever vaccination. Additionally, the vaccine should not be given to children under six months of age or individuals with allergies to albumin. If you are over 60 years of age, may be pregnant, or are breastfeeding, please consult a doctor before vaccination. In all other circumstances, be sure to visit your closest immunization clinic a month before traveling!
