Infectious Diseases Definition, Symptoms, Causes।     

Infectious Diseases, contagious disease
Infectious Diseases Definition / Contagious Diseases     

In medical terms, infection refers to the penetration, invasion, multiplication, reaction, and toxicity of pathogens into the host cells.  Thus, the disease caused by the infection is called contagious or infectious disease.
 These diseases are caused by viruses, prunes, bacteria, nematodes, ants, arthropods and various types of fungi.  And the branch of medicine that studies infections is called infectious pathology.

Types of diseases in human body : 
Diseases of the human body can be divided into two main categories. 

 (A) Infectious disease or contagious disease. 
 (B) Non-infectious or non-infectious disease. 

 The first diseases are caused by germs and viruses, so they can spread from one person to another.  In fact, the spread of the disease is closely linked to the human body's immune system.  Numerous pathogens are circulating outside the human body, but they cannot enter the human body if they want to.  This barrier is saving people from various diseases.  But in certain cases, when the immune system of the human body becomes weak, all those germs enter the human body.  Then people get sick.

Infectious Diseases Definition : 

There are some diseases that spread from one person to another.  The germs of these diseases are spread through the phlegm, saliva, sneeze and cough of the patient and they are called Infectious Diseases Or contagious diseases.

Now let's find out about the 5 most terrible infectious diseases in human history.  And let me start with you, my acquaintance with the most terrible infectious disease.

Covid-19 / Corona Virus  : 

Contagious disease
Infectious Diseases covid-19/corona virus   

 Are you surprised to see the name of the deadly Covid-19 or Corona at the beginning of the list?  So for your information, this terrible infectious disease has so far claimed more than 2 lakh 26 thousand lives.  So far the world has not been able to take any effective steps to stop its transmission.
 And so the experts still can't say when this death game will end, and how many lives will be lost.

What Is The Corona Virus? Symptoms Of Corona Virus         

 Plague : 

Contagious disease, infectious disease
Infectious Diseases plague  

 Plague broke out in 541 AD in Justinian of the Roman Empire.  The deadly disease has been circulating in the Middle East, Asia and the Mediterranean for nearly two centuries.  Plague is by far the most deadly infectious disease in human history.  In the last two hundred years, about 100 million people have died from this bacterial disease.

 Rabies : 

 The rabies virus is neurotropic, meaning it spreads from animals to humans.  The disease caused by this virus is called rabies.  According to the Pasteur Institute in Paris, 59,000 people die of rabies every year around the world.  The rabies virus spreads in the saliva of infected animals.
 When the rabies virus spreads to the brain, the symptoms of rabies begin to appear.  Within three to five days of the onset of symptoms, the patient dies of severe convulsions and paralysis.

 Chicken Pox  : 

Contagious disease chicken pox.

We are all more or less familiar with guti spring.  Now no one is afraid of this infectious disease.  And this contribution is to medical science.
 In the early seventeenth century, the disease spread to Europe, France, the United Kingdom, and the Netherlands.  Even in the state of Massachusetts in the United States, there was a time when Spalpox was infected.
 Apart from this, the infectious disease had spread to many other countries at different times.  Historians claim that about 20 million people have died as a result.

 Ebola : 

Contagious disease ebola.
Infectious Diseases Ebola   

 Before Corona, Ebola was considered the most contagious in human history.  So far six variants have been identified.  The death rate from infection is more than 25 percent to 90 percent.
 To date, no effective antidote to the virus has been developed.  From the blood, saliva or any secretions of people infected with the Ebola virus.  Ebola is also transmitted to other people through wounds.
 The deadly corona virus has been placed here in the beginning because no other virus has been able to spread the infection on such a global scale before.  With the advancement of knowledge science in human civilization, there has been an improvement in the system of communication.  And by doing so, this infectious disease is spreading rapidly all over the world in a very short time.

Hepatitis B : 

Contagious disease hepatitis b
Infectious Diseases Hepatitis B   

Hepatitis B damages the liver.  It can cause acute (immediate) and incurable (long-term) health problems.  Children born infected at birth or in the first year of life have a 9 out of 10 (90%) chance of developing a lifelong hepatitis B infection.  This can lead to liver infections and diseases like cancer.

 HIV : 

Contagious disease HIV / AIDS.
Infectious Diseases HIV Virus / AIDS   

HIV weakens the immune system, making it harder to fight infection.  If left untreated, it can be passed from mother to baby during pregnancy, birth or breastfeeding.  Treatment during pregnancy can significantly reduce the risk of HIV transmission in the baby from 1 in 4 (25%) to 1 in 200 (0.5%).

 Syphilis : 

Infectious Diseases Sifilis
Infectious Diseases / Contagious disease     

Syphilis is an infectious disease that is spread through sexual contact.  During pregnancy it can spread from mother to baby.  If left untreated, it can lead to serious health problems for the baby or premature abortion or stillbirth.

Dengue fever : 

Contagious disease Dengue Fever.
Infectious Diseases Dengue Fever    

Dengue fever is caused by the dengue virus and is carried by mosquito bites called Aedes aegypti.  If a person is bitten by a mosquito carrying dengue fever, that person gets dengue fever within 4 to 6 days.  This time, if an infected person is bitten by a sterile Aedes mosquito, that mosquito also becomes a dengue-carrying mosquito.  In this way dengue is spread from one person to another through mosquitoes.

 There are two main types of dengue, classical dengue fever and dengue hemorrhagic fever.

Influenza : 

Infectious disease influenza.
Infectious Diseases Influenza    

We all know the name influenza . It is commonly known as the flu . The flu is usually caused by the viruses Orthomyxoviridae.  Mammals and birds are infected with this virus. 

What are the symptoms of the flu?

  Symptoms of the flu usually include fever, headache, muscle aches, cough, and weakness.  Sometimes vomiting may occur  Especially in case of flu, the patient must have cough and fever  If the level of flu is high, the patient may get pneumonia

  The flu virus is usually spread through sneezing and coughing and is transmitted to mammals.  The virus is also spread from bird droppings  The flu virus is also spread from saliva and blood  Therefore, sneezing, coughing, or spitting should be avoided where the flu occurs.

  According to researchers, between two and a half million and five million people die from the flu every year around the world.  However, when this type of flu takes a terrible turn, it spreads to the whole world in the form of an epidemic in a short period of time.  This is usually seen every three to four decades  For example, in 18 months in 1918, four crore people died all over the world  In 1968, another type of flu killed about 1 million people  We have been hearing about bird flu for the last few years  Many people have lost their lives due to this flu  The latest outbreak of swine flu has been reported  The flu has started from Mexico. But gradually it has spread from continent to continent  The number of people infected with swine flu is already more than 100.

 Scabies is an infectious disease.  It is caused by an infection of a small mite called sarcoptes scabies.  This parasite prefers to live in a warm environment.  The female mites lay two to three eggs daily for six weeks.  Later baby mites are born from the eggs.  Since the disease is contagious, other family members are more likely to be infected.  You do not need a doctor to diagnose scabies.

 You can diagnose scabies yourself.  Unusual itching at night is the main symptom of scabies.  At this time, due to the heat of the bed, the mites started moving under the skin.  It feels more itchy at night.  As a result of itching, the skin gets scratched on the nails.  For this, scratch marks are also found on the body.  Tiny black thread-like lines can be seen on the affected area.  It's called twelve.  At the end of this line there are small grains or small grains with water.  These grains are the habitat of mites.  This is where they lay their eggs.  In women, itchy small rashes usually appear around the nipples and in men, itchy scars on the testicles and genitals.  Many times bacterial infections occur in scabies.  There are certain medicines for scabies.


 If it is used according to certain rules, scabies can be cured.  In addition to using medicine, clothes should be boiled and glass should be given and bed-mattress should be given in the sun.  However, you must consult a doctor before taking any medicine.
