Mosquito Bite is Life Threatening

A healthy life is a happy life. They say, “An Apple a Day Would Keep the Doctor Away”. However, apple is not able to heal every illness. Nobody wants the illness, especially if it comes from a tiny creature as a mosquito. The smaller they are, the deadliest they are. It is said, “Chota Packet Bada Dhamal (The smallest packet makes the greatest noise)”. Well, the same case is with these tiny creatures. Mosquitoes bite you and you just feel a little irritation on your skin, which automatically vanishes after a small amount of time. This is as normal as a part of daily routine. Who bothers about a small bite, which is not even noticeable? However, such ignorance can convert into a life-taking event too. Mosquito bites can make you extremely sick or can even take away your life. The infection is spread only by the mosquito bite, but not from person to person. If a mosquito bites an infected one and then bites a healthy person, it passes the virus to the healthy person as well. This clearly shows that a small mosquito bite can be life threating.

Below is the list of few deadly diseases, caused by a mosquito bite.

Zika Virus:

The latest known virus in India is the Zika Virus. It was first discovered in Uganda in 1947. A pregnant Brazilian woman, infected with this virus, gave birth to abnormal babies having small heads, which further resulted in incomplete brain development, known as Microcephaly. The virus did not only affect their brains, they were also linked with Guillain-Barre syndrome, where the body is in risk of getting paralysed as the healthy nerve cells in the nervous system are attacked by the immune system.

It does not show any particular signs of illness after the infection, therefore, mostly get unnoticed. The normal symptoms are fever, rash, and joint pain. The disease is mostly spread in the daytime like dengue. In case of pregnancy, it can cause deadly diseases to the new born like brain damage, blindness, deafness or seizures.

The virus originated in Africa, then reached America and lately, it has found in India as well, although the cases are very low in number but still, it is a matter of concern.


Dengue Virus (DENV) is a cause of Dengue Fever, which can be a life threatening disease, as Dengue Haemorrhagic Fever (DHF) or Dengue Shock Syndrome (DSS), if not treated on time.

There are 5 different Serotypes of this virus: DENV-1, DENV-2, DENV-3, DENV-4, and DENV-5.

The symptoms that are usually visible after the 4-7 bites of a mosquito are:

  • High fever,
  • A severe headache,
  • joint or muscle pain,
  • rashes on the body,
  • nausea or vomiting, or
  • Pain behind the eyes.

If the situations get worse, there are chances of Dengue Haemorrhagic Fever.

The symptoms include:

  • Bleeding gums
  • Nose bleeding
  • Easy lesion/bruises

DSS-Dengue Shock Syndrome can show symptoms like extreme swelling, bleeding or very low blood pressure.


Infected Anopheles mosquito passes the infection to humans by biting. The Plasmodium parasite is passed from the mosquito to the human body and releases into the blood. It travels to the liver to get mature, after which they attack the Red Blood Cell (RBC) in the blood stream. This virus keeps multiplying itself in the RBCs.

If a mother is infected with malaria, this can be transferred to the new born, known as Congenital Malaria.

The symptoms are usually shown in 10 to 25 days which include high fever, sweating. A headache, nausea, vomiting, abdominal pain, diarrhoea, anaemia, muscle pain, seizures, coma or bloody stool.

Life threatening consequences of Malaria:

  • Blood vessels of brain swell up,
  • fluid accumulation in lungs results in breathing problem,
  • anaemia, or
  • low blood sugar.


A mosquito infected with Aedes Aegypti can cause Chikungunya and dengue as well. It shows the symptoms same as dengue. Although it is not a life threatening disease, it is able to cause limb deformities for a long period. Being dependent on someone else is worse than death. There is no vaccine for it until date; therefore, prevention is better than cure.

Lymphatic Filariasis:

Another name is Elephantiasis. It damages the lymphatic system, responsible to transport lymph (a fluid), which fight against infections throughout the body. The lymph nodes are located around the lungs, heart, and kidney, near the surface under the arms or groin. This results in increasing the infections as there will be no antibodies after the lymphatic damage. The LF can result in painful and swollen limbs as well.

There are three types of Filarial worms:

  • Wuchereria Bancrofti
  • Brugia Malayi
  • Brugia Timori

According to a report in Hindustan Times, Wuchereria Bancrofti causes 99.4% LF cases.

Common symptoms include fever or vomiting, but severe symptoms can cause swelling of arms, legs or chest as well in genital areas, where it’s extremely painful. The swelling may appear years after the infection, therefore can be ignored with a common cold at the initial stage.

Mostly the infected mosquitoes will show white lines on their bodies.

All these deadly diseases show nearly common symptoms at the beginning. Therefore, it is better to not ignore any small hint. Consult your doctor if you find any of these symptoms if they are staying for more than 1-2 days, or even if re-occurring.
