Infectious Diseases - Disease, Causes, Symptoms, Treatment, Prevention

Infectious diseases are illnesses caused by organisms like bacteria, viruses, fungi, or parasites. There are numerous organisms that live in and on our bodies.

What is a disease?

A disease is a condition in which certain functions of the body get disturbed and makes the person feel sick.

Certain disease are caused by microrganisms such as bacteria, viruses, and fungi. Microrganism  are extreamly  small living things that can been seen only with the microscope. Disease causing microrganisms are called germs or pathogens.

Not all microrganisms cause disease.Some are useful to us.Cheese,bread and curd are made with the help of microrganisms.Many kinds of microrganisms live in the human body.Some of these organisms help in digesting food.

Where do germs live?

Germs live everywhere.They are present in air,in unclean water,and also in the soil.They also live inside the body of animals and plants.

Does every disease has definite symptoms?

Yes,Every disease causing germs affects the body in a certain way.For Example:the virus that causes common cold affects the throath and lungs of the person.That is why a person suffering from common cold coughs and has a running nose.These are the symptoms of common cold.

Similarly,if a person vomits and passes watery stoolseveral times in a day,the person could be suffering from cholera.By studing the sympytoms,the doctors are able to identify the disease.

Communicable or infectious disease:

Some disease can be passed on from a sick person to another person. Such disease are called infectious disease or communicable disease. Cholera, tuberculosis[TB], typhoid, and common cold etc are infectious disease. At this time a person suffering from an infectious disease is shifted to a for proper care.

The infectious disease are as follows:

cholera (Infectious diseases)

  CAUSES//

Cholera is a severe diarrheal illness caused by a Vibrio cholerae bacterial infection of the intestine. People can become ill if they consume cholera-contaminated food or water. The infection is frequently mild or without symptoms, but it can occasionally be severe and life-threatening.

It is also caused by contaminated food and water, as well as contact with an infected individual.

  SYMPTOMS//

vomiting,thirst,leg cramps,restlessness or irritability And profuse watery diarrhoea, also known as “rice-water stools”etc.

 TREATMENT//

The primary treatment for cholera patients is rehydration therapy, which refers to the prompt replenishment of lost fluids and salts. Antibiotic treatment reduces fluid requirements and illness duration in severe cases of cholera.

*vomiting.

*abdominal pain.

*Body ache.

*Chills.etc

                   TREATMENT//

Malaria, a treatable disease, kills over 400 000 people each year. Both early diagnosis and treatment of malaria are critical for rapid and effective case management of the disease.

loss of taste or smell.

Serious symptoms:

difficulty breathing or shortness of breath.

chest pain or pressure.

loss of speech or movement.

                       TREATMENT//

Isolate yourself in a well ventilated room.

Monitor temperature daily.

*Use a triple layer medical mask, and discard it after 8 hours or sooner if it becomes wet or visibly soiled. If a caregiver enters the room, both the caregiver and the patient should consider using a N 95 mask.

*Personal items should not be shared with other members of the household.

Black Fungus (Infectious diseases)

            CAUSES//

In general, some fungi do not cause infections in humans, but they can cause illness in people with weakened immune systems, which is known as opportunistic infections.

           SYMPTOMS//

Mucormycosis begins as a skin infection in the air pockets behind our brows, noses, cheekbones, and between our eyes and teeth. It then spreads to the eyes, lungs, and even the brain. It causes nose blackening or discoloration, blurred or double vision, chest pain, breathing difficulties, and blood coughing.

            TREATMENT//

After infecting a person, the fungus spreads through the nose, attacks the eyes, and eventually reaches the brain, where it becomes potentially lethal. To treat, this necessitates multidisciplinary expertise.

Mucormycosis affects a variety of body parts in the majority of cases, especially if it goes undetected for an extended period of time. As a result, a multidisciplinary team of microbiologists, internal medicine specialists, intensivist neurologists, ENT specialists, ophthalmologists, dentists, surgeons, and others is required.

All infected tissues must be surgically removed as part of life-saving procedures. Some patients lose an eye or eyes, and in some cases, the upper jaw.

Patients may require an intravenous antifungal procedure that lasts four to six weeks.

ALWAYS KEEP YOUR SURRONDINGS CLEAN SO THAT NO PERSON    SHOULD GET INFECTED AND THE DISEASES CAN EASILY STOP SREADING.     “CLEAN PERSON IS A HEALTHY PERSON”
