A fever is a temporary increase in your body temperature, often due to an illness. Having a fever is a sign that something out of the ordinary is going on in your body.

For an adult, a fever may be uncomfortable, but usually isn't a cause for concern unless it reaches 103 F (39.4 C) or higher. For infants and toddlers, a slightly elevated temperature may indicate a serious infection.

Fevers generally go away within a few days. A number of over-the-counter medications lower a fever, but sometimes it's better left untreated. Fever seems to play a key role in helping your body fight off a number of infections.


  • Sweating
  • Chills and shivering
  • Headache
  • Muscle aches
  • Loss of appetite
  • Irritability
  • Dehydration
  • General weakness





Filariasis is caused by several round, coiled and thread-like parasitic worms that belongs to the family filaridea. These parasites penetrate the skin either   their own or through the opening created by mosquito bites to reach the lymphatic system.



Lymphatic filariasis infection involves asymptomatic, acute, and chronic conditions. The majority of infections are asymptomatic, showing no external signs of infection, although their blood is positive for microfilaria. This stage may lasts for months. Acute episodes of local inflammation involving skin, lymph nodes and lymphatic vessels. Chronic condition shows  oedema with thickening of the skin and underlying tissues.

It usually affects the lower extremities. However, the arms, vulva, breasts and scrotum (causing hydrocele formation) can also be affected. The oedema  in the extremities, breast or genital area can result in the part becoming  several times its normal size and is due to blockage of the vessels of the lymphatic system.





Hay fever

Hay fever, also called allergic rhinitis, causes cold-like signs and symptoms, such as a runny nose, itchy eyes, congestion, sneezing and sinus pressure. But unlike a cold, hay fever isn't caused by a virus. Hay fever is caused by an allergic response to outdoor or indoor allergens, such as pollen, dust mites, or tiny flecks of skin and saliva shed by cats, dogs, and other animals with fur or feathers (pet dander).


Hay fever signs and symptoms can include:

Runny nose and nasal congestion

Watery, itchy, red eyes (allergic conjunctivitis)



Itchy nose, roof of mouth or throat

Swollen, blue-colored skin under the eyes (allergic shiners)

Postnasal drip




Loose motions


Colon and small intestine  Everyone occasionally has diarrhea — loose, watery and possibly more-frequent bowel movements.  In most cases, diarrhea lasts a couple of days. But when diarrhea lasts for weeks, it can indicate a serious disorder, such as a persistent infection, inflammatory bowel disease, or a less serious condition, such as irritable bowel syndrome.


Loose, watery stools

Abdominal cramps

Abdominal pain


Blood in the stool



Urgent need to have a bowel movement





Malaria is a disease caused by a parasite. The parasite is transmitted to humans through the bites of infected Anopheles  mosquitoes. People who have malaria usually feel very sick, with a high fever and shaking chills. Once the parasites are inside your body, they travel to the liver, where they mature. After several days, the mature parasites enter the bloodstream and begin to infect red blood cells.



A malaria infection is generally characterized by the following signs and symptoms:

  • Fever
  • Chills
  • Headache
  • Nausea and vomiting
  • Muscle pain and fatigue






Measles is a childhood infection caused by a virus. Once quite common, measles can now almost always be prevented with a vaccine.

Also called rubeola, measles can be serious and even fatal for small children. While death rates have been falling worldwide as more children receive the measles vaccine, the disease still kills more than 100,000 people a year, most under the age of 5.

As a result of high vaccination rates in general, measles hasn't been widespread in the United States for more than a decade. The United States averaged about 60 cases of measles a year from 2000 to 2010, but the average number of cases jumped to 205 a year in recent years. Most of these cases originate outside the country and occurred in people who were unvaccinated or who didn't know whether or not they had been vaccinated.


Measles signs and symptoms appear around 10 to 14 days after exposure to the virus. Signs and symptoms of measles typically include:

  • Fever
  • Dry cough
  • Runny nose
  • Sore throat
  • Inflamed eyes (conjunctivitis)
  • Tiny white spots with bluish-white centers on a red background found inside the mouth on the inner lining of the cheek — also called Koplik's spots
  • A skin rash made up of large, flat blotches that often flow into one another




Poliomyelitis or called as Polio is a viral disease that destroys the nerve cells present in the spinal cord causing paralysis of some parts of the body or causing muscle weakness. It is a contagious disease affecting the nervous system and is caused by poliovirus.
Poliovirus can also be transmitted from one person to another through the fecal matter. It even spreads through contaminated foods. The virus mainly affects the children within the age of 5. The body parts which are infected by this disease are legs, neck, head. There is no any cure for polio; hence it has to be prevented by taking polio vaccine at the early age.


Symptoms of Poliomyelitis

The initial symptoms of Poliomyelitis are given below-

Severe fever

Excess fatigue

Vomiting sensation

Pain in limbs

Sore throat

Frequent headaches

Back pain, leg pain

Stiffness in the muscles and neck areas

Limb deformities

Paralysis of some parts of the body


Develop weakness in the body

Problems with breathing
