Yellow fever : Symptoms, Causes & Treatment

Yellow fever

People get yellow fever, a virus, from infected mosquitoes. The symptoms might be anything from minor ones like fever and bodily pains to more severe ones like organ failure. It can be fatal, but getting a vaccination can also help avoid it.

Yellow Fever

A virus called yellow fever is transmitted by the bite of certain species of mosquito. When mosquitoes bite virus-carrying primates, they get infectious. Yellow fever virus symptoms might differ from person to person. Not everyone experiences symptoms.

In its most severe form, it can be fatal, although it can also show up with mild flu-like symptoms. You can experience fever, aches, and pains similar to the flu, or you might start bleeding and get liver damage. It takes three to six days for symptoms to appear.

Symptoms

Yellow fever may happen without signs of illness. In case you do exhibit its symptoms, they may vary in intensity. Less severe signs and symptoms might be:

  • High temperature.
  • body pain.
  • Exhaustion (fatigue).
  • vomiting as well as nausea.

More severe signs are:

  • Very high fever.
  • Jaundice
  • Hemorrhage (bleeding).
  • Shock.
  • Liver failure.
  • Kidney failure

Why Does Yellow Fever Occur?

When an infected mosquito bites you, the yellow fever virus, also known as the flavivirus, causes the illness. When a mosquito bites a person or a monkey with the virus, it can infect the mosquito itself. There is no way for the illness to transfer between individuals.

Mosquitoes reproduce around still water sources, in humid and semi-humid conditions, and in tropical rainforests. Small-scale epidemics can be caused by increased human-infected mosquito contact. Especially in places where people are not immune to this virus.

Diagnosis

If you feel like you have the flu and have just traveled, go in to see your doctor. Your physician will inquire about the symptoms you have been having as well as any recent travel history. Also, your doctor will request a blood test if they think you have yellow fever. They will examine your blood sample to see if the virus or any antiviral antibodies are present.

Treatment

Yellow fever does not have a cure. As part of treatment, you will be able to manage your symptoms. Also, help your immune system fight off the infection by:

  • Consuming enough liquids, perhaps via your veins
  • Obtaining oxygen
  • Preserving a normal blood pressure level
  • Receiving blood replacements
  • Undergoing dialysis in the event of renal failure
  • Receiving care for potential further infections

The Bottom Line

A virus called yellow fever is contracted in some regions of Africa and South America and is transmitted by mosquito bites. It can be deadly, but if you receive the vaccination, you can completely avoid it. To try to prevent mosquito bites, you can also wear protective clothes and use insect repellent.

Some places run programs to control mosquitoes. Speak with your healthcare practitioner if you have symptoms such as fever or body pains. Also, talk to your doctor if you have traveled to a region where this medical problem outbreak has been reported.
