Yellow Fever - Symptom, Treatment And Causes

Infected mosquitoes generally spread yellow fever to humans. Contaminated syringes are the only way humans can transmit the infection to each other. It can’t be transmitted directly from one person to another. Sevearl mosquito species can transmit the virus responsible for causing yellow fever. The virus is transmitted by mosquitoes in urban areas as well as jungles. Monkeys can also get infected by this virus. The skin becomes yellow due to liver damage.

The initial symptoms may not appear in few people while others may get the symptoms within six days of being bit. There are three phases in yellow fever. The first one lasts up to four days and has symptoms of flu like headache, vomiting, chills, fever and muscle aches. Remission is the next phase and lasts up to 48 hours. Most people recover during this phase. However a toxic third phase might be there for few people. Viral hemorrhagic fever may develop and internal bleeding, high fever and kidney and liver damage may take place. It may cause multiple organs to stop functioning due to shock and may cause death.


Blood tests and checking the symptoms should suffice to detect yellow fever. It may have overlapping symptoms with other tropical diseases like typhoid and malaria.


As it has no cure, treating the symptoms can bring relief. Hospitalization may be required and drugs like aspirin (which is a non-steroidal anti-inflammatory drug) shouldn’t be taken as it may worsen internal bleeding. You should get vaccinated before travelling to places where the incidences of yellow fever are high. Tropical areas like Latin America and Africa have mandatory vaccinations before you enter the country.


The vaccine for yellow fever isn’t suitable for everyone. It may result in serious complications in some people. Attempts to make a safer killed vaccine for yellow fever are under way.

Here are some instances where you shouldn’t get vaccinated for yellow fever:

  • If your immune system is compromised, in instances like HIV
  • If you have thymus gland issues or cancer
  • If your treatment for other conditions can affect the immunity, like steroids
  • If you are above 65 years.
  • If you are breastfeeding or pregnant
  • If your child is under one year of age.
  • If you have had severe allergic reactions to chicken, gelatin, eggs or a previous yellow fever vaccine.
Treatable by medical professional Require medical diagnosis Lab test not required Short-term: resolves within days to weeks Non communicable
Fever with skin becoming yellow Muscular pain along with headache Vomiting

Zika Virus - How You Can Prevent Yourself?
Zika virus causes a deadly disease called Zika fever or Zika virus disease that spreads by the bite of the Aedes mosquito. The Zika virus is a member of the virus family FLAVIVIRIDAE and is closely related to the dengue, yellow fever, Japanese Encephalitis, and West Nile viruses. It was isolated in the Zika forest of Uganda in 1947 and is known to be prevalent in continents like Africa and Asia primarily, though it s slowly making headway in the developed world and has spawned the deadly 2015-2016 Zika virus epidemic. What are symptoms of Zika fever? People with Zika virus disease can have symptoms which are similar to Dengue, like- Fever Diarrhea Red Eye Muscle Pain Skin Rash Headache These symptoms usually last for 2-7 days. Complications of Zika virus disease According to WHO, Zika virus infection during pregnancy causes congenital brain abnormalities like microcephaly. And the infection can also trigger the Guillain-Barr syndrome. Microcephaly is a condition where a child is born with a small head or the head stops growing after birth and the Guillain-Barr syndrome is a rare condition in which a person s immune system attacks the peripheral nerves which control muscle movement and sensation. Even as we read this, intense efforts are being expended to investigate the link between Zika virus and a number of other neurological disorders. How does Zika spread? The causes of Zika are: The bite of the Aedes mosquito that is infected with the Zika virus. This mosquito is the same that spreads dengue, chikungunya, and yellow fever. It bites primarily in the daytime. Unprotected sexual intercourse Zika s transmission through blood transfusion is being investigated. How can you prevent Zika infection? Protection against mosquito bites is the most foolproof ways to prevent a Zika virus infection. Other ways to prevent Zika infection via mosquito bites are: Just like Dengue prevention, you must cover your body properly, especially during daytime Use physical barriers such as window screens or closing doors and windows against the mosquitoes Sleep under mosquito nets Using insect repellents containing DEET, IR3535 or icaridin Take extra care of young children, sick and elderly people Cover, empty or clean mosquito breeding sites in and around your house or colony like empty buckets, drums, flower pots and used tyres that can fill-up with water and breed mosquitoes Encourage your family and community to support local government efforts to reduce mosquitoes in their localities Insist on regular spraying of insecticide for mosquito control in your locality. For stemming sexual transmission of Zika, the WHO recommends that sexually active men and women be counselled to practice safe sex using condoms. WHO also recommends that people who have come back after travelling from Zika virus zones should be extremely careful in practising safe sex or abstinence for the first 6 months at least, for preventing a pregnancy. If affected, what is the treatment? Zika virus disease is usually mild and requires no specific treatment as such. Infected people are advised plenty of rest, asked to drink enough fluids, and treat pain and fever with common medicines like Ibuprofen. However, if symptoms worsen, you must seek advise from a medical practitioner.

I have tried last three days and I have fever my body last two day and my urin is yellow and my eyes is yellow.

Dr. Amar Deep 91% (13386 ratings)

Please take rhus tox 200 - thrice daily for next 3-4 days. Also -- soak a washcloth in cool tap water, wring out the excess water and then sponge areas like your armpits, feet, hands and groin to reduce the temperature. Also, you can place cold, damp washcloths on your forehead and the back of your neck. The cloth pieces should be changed regularly after a few minutes. This remedy is beneficial when dealing with a high fever as it helps keep temperature under control. You can also take a bath in lukewarm water to relax your body. Taking a shower, however, may not be a good idea. Plus, needless to say, take as much rest as possible as it helps the body fight the illness. Note: do not use very cold water as it may cause the internal body temperature to increase.
