​Yellow Fever


Yellow fever is an infection caused by a virus which spreads through bite of a special and rare kind of mosquito. Once bitten, the virus affects the liver and other organs of the body eventually proving fatal.

These specific species of mosquitos usually breed in urban areas.

The primary symptoms of this disease are flu and yellowing of skin. The yellowing of skin is usually because the virus affects the liver and causes jaundice. The symptoms usually occur in 3 phases. After the first phase, the symptoms vanish completely. The first phase, cannot be identified separately as it does not hold any distinguishing symptoms from a common infection.

First Phase:

  • Flu like symptoms

  • Headache

  • Body ache

  • Vomiting

  • Fever and chills

Second Phase:

  • Weak pulse

  • Extreme and dense yellowing of skin

  • Bloody urine

  • Bloody stool

  • Bleeding of gums

Third Phase:

  • Internal bleeding or haemorrhaging

  • Shock

  • Multiple organ failure

  • Jaundice

The above symptoms will start to show 3 to 6 days after youare exposed to the virus. If you feel your skin is yellowing accompanied with a fever, you should get yourself examined by the doctors at the Internal Medicine Services at The Aga Khan University Hospital immediately. Yellow fever usually has similar symptoms to malaria and typhoid, so if you have recently travelled to a high-risk country, it is highly recommended that you keep a check on this condition and track your symptoms.

Your time with your doctor maybe limited, so make sure to prepare for your visit beforehand. Here are some tips to help get you started.

Yellow fever is cannot be objectively diagnosed. The doctors will conduct your full body examination. They will also get some blood tests done to rule out other infections and determine whether the virus itself or antibodies against it have developed or not.

Yellow fever has no set treatment. Therefore, your doctor will treat you symptomatically. This means, treating you for fever, body pains, vomits and dehydration. The infected is very likely to start bleeding internally; hence drugs not prescribed by your doctor should be strictly avoided. The doctors will hospitalize you to monitor you response to the medicines and track your progress.
