Infectious Disease

What Is Infectious Disease?

Infectious disease is a medical condition that develops when the pathogenic microorganisms invade the human body. These microorganisms include viruses, parasites, bacteria, and fungi. Many of them actually peacefully coexist with humans and humans stay healthy. But under specific circumstances, these microorganisms become the enemies for the human body. And an infectious disease develops. The major common feature of all infectious diseases is that they are extremely contagious.

Tips to Avoid Infectious Diseases?

There are several well-working tips to prevent infectious diseases:

  • Keep Your Hands Clean: This is a key rule you always must abide by for the prevention of any infectious disease. It’s very important to wash the hands prior and after cooking food, prior eating, and of course after going to the toilet. Also, it’s not advisable to touch the mouth, nose, and eyes even with seemingly clean hands since it’s a direct way for infectious agents to intrude into the human body.
  • Don’t Forget about Vaccination: You must get vaccinated in full and on time. It’s an absolutely sure method to considerably decrease the probability of becoming infected with many life-threatening contagious diseases. You and your children should conscientiously adhere to your vaccination schedules.
  • Cook Food Properly: When you choose the best fat burner for women and other supplements, you shouldn’t also forget about safety of food you choose for eating in order to prevent any infectious diseases. It’s also crucial to wash foods before eating and cooking; cook foods by selecting the right temperature; timely use the refrigerator to safe foods before it spoils; and maintain kitchen itself and kitchen utensils clean.
  • Don’t Use Other People’s Personal Things: You should always remember that the personal hygiene items are really individual. It means you must have only your own hygiene body kit including own comb, toothbrush, razor, and towel. It’s strongly also not recommended to give someone your own dining utensils and dishware.
  • Take Care of Travel Safety: If you are going to travel outside the country where you are living, you should consult your healthcare provider concerning the reasonability of additional vaccination. Thus, it may be advisable to get a shot of vaccines against hepatitis A, hepatitis B, yellow fever, typhoid fever, and cholera.

Symptoms of Infectious Diseases

People may experience a multitude of infection symptoms because there are plenty of different infections able to afflict a human body. It’s possible to distinguish a range of most widespread symptoms, which can make people suspect they became infected:

  • Chills or fever
  • Muscle pain
  • Unexplained severe fatigue
  • Coughing
  • Indigestion accompanied with diarrhea, nausea, and vomiting

These symptoms sometimes disappear soon. But in some cases, you have to urgently seek for a medical aid. This is required in the following cases:

  • Aggravation of symptoms even provided that at-home treatment was administered
  • Substantial prolongation or recurrence of symptoms, for example a long-lasting coughing
  • Trouble breathing
  • Very strong headache accompanied with severe fever
  • Swelling of unexplained origin
  • Rash
  • Animal or insect bite
  • Sudden vision deterioration

In some cases, people may be contaminated but have no symptoms of infection. Such a situation may happen chlamydia, gonorrhea or HPV infects a person. But if you yet experience the symptoms of infectious disease and at the same time take any all-natural diet pills for women, you should inform your doctor who is going to treat the infectious disease in case of establishing a diagnosis.

Causes of Infectious Diseases

There are the following major types of infectious disease causes:

  • Bacteria: They are the single-celled organisms which lead to the development of tuberculosis, meningitis, urinary tract infections, pneumonia, and food poisoning. Bacteria reproduction in the body occurs very quickly. And due to this, toxicity and contagiousness of these microorganisms increases dramatically.
  • Viruses: They are the infectious agents of extremely small size. Their multiplication happens only in the living cells of people, animals and even bacteria and plants. Viruses provoke the development of numerous common infections like cold and flu. Among the most dangerous viral infections, there are AIDS, Ebola, and smallpox.
  • Fungi: Fungal infections primarily afflict skin, causing ringworm, candidiasis, and athlete’s foot. The nervous system and lungs may also suffer from fungi.
  • Parasites: Insect bites and animal feces are the main ways of parasite transmission. Parasitic infections such as malaria, port tapeworm, and hidden lung worm can be very dangerous and even deathful.

How Common Infectious Diseases Are

Infectious diseases are very widespread all over the globe. According to the international statistics provided by the WHO, approximately 50,000 people including women, men, and children per day are bereft of life because of infectious diseases. Also, more than 17 million people per year pass away because infectious diseases become fatal to them.

There are infectious diseases which afflict people much more frequently than the other medical conditions of infectious origin. For example, 1 out of 5 Americans becomes contaminated with influenza virus very year.

Also, the situation with the emergence of infectious diseases aggravates from year to year since the new infectious conditions are now appearing too quickly and frequently. Since antibiotic resistance has already become a great threat, both long-existing and newly-emerged infections endanger the health and life of hundreds of millions of people worldwide.

Infectious Disease Complications

Some of the infectious diseases are self-curing while the others are successfully treated. A large number of infectious diseases provoke a wide range of complications which may vary from mild to very dangerous ones.
Among the mild infectious disease complications, it’s possible to distinguish enormous tiredness, skin rash, and stredulous breathing. Such mild complications typically vanish when the person is fully recovered after a particular infectious disease.
But there are the infections which put the human life into jeopardy. Such diseases include but are not limited to pneumonia, dengue, HIV, hepatitis B, hepatitis C, tuberculosis, and human papilloma virus. These diseases may provoke the life-endangering complications, for example liver cancer and cervical cancer. Mortality rate for severe infectious complications is quite high.
The most commonly occurring infection complications are related to urinary tract infections, pneumonia, and wound infections. There are also the risk factors for infectious disease complications. Among these factors, there are drug abuse, pre-existing stroke, cirrhosis, female gender, dementia, high injury severity score, and poor access to healthcare.

Stages of Infectious Disease Development

It’s possible to distinguish the following stages which each infectious disease runs in the human body:

  • Incubation period: This period implies the time between the first patient’s contact with an infectious agent and the occurrence of very first noticeable symptoms.
  • Prodromal period: At this time, the patient’s symptoms progress from mild to moderate ones.
  • Invasive period: During this stage, the disease reaches its culminative point and the patient suffers from the disease toxicity and symptoms to the greatest extent.
  • Convalescence period: This phase is marked with the recovery from disease. The use of medically approved appetite suppressants and other natural remedies can’t slow down this process.

Modes of Infection Disease Transmission

Infectious diseases are mainly transmitted through direct contact and indirect contact.

Direct contact

The most widespread way to become infected is to contact with either a human or an animal who is already infected. It’s possible to distinguish three major ways contagious agents can pass from one living being to another one via direct contact:

  • Person to person: This is the way which most frequently contributes to infection transmission. In this case, viruses, bacteria, fungi, and other organisms, which cause infections, can be directly spread from human to human. The contamination happens when an infected person closely contacts with a non-infected person. Such a contact implies kissing and touching as well as sneezing or coughing on a healthy person. And this is how a healthy person catches the contagious agents.
  • The exposure to semen and vaginal fluid excreted during sex are also the sources of direct contact infections. The contamination which occurs in such a way doesn’t mean that a person will obligatorily have the infectious disease signs while this person will become a carrier.
  • Animal to person: Infected animals including pets can transmit infectious agents when these animals bite or scratch people. The infections transmitted through animals can be very dangerous and even lead to a person’s death. It may be also unsafe dealing with animal waste, which may for example infect a person with life-threatening toxoplasmosis.
  • Mother to unborn child: A mother can infect the unborn infant with pathogenic microorganisms, provoking an intrauterine infection. And the intake of folic acid can’t prevent this. There are the infectious agents for which the placenta is not a barrier and they easily go through it. A mother’s vaginal infections can be also passed to a baby.

Indirect contact

Indirect contact can also provoke the transmission of germs. Pathogenic microorganisms can remain on different surfaces and objects for a long time and hence pose a real infection threat to the people’s health. If you for example attend a gym, never share your towel, testosterone boosters bottle, or any other personal things in order to avoid indirect contact infections. Also, the surfaces in the public facilities can become the places where a person may get infected if these surfaces are not properly disinfected.

Risk Factors of Infectious Diseases

Infectious diseases are a kind of medical conditions which can affect virtually every person regardless of age, gender, and social status. But people with underperforming immune system are more predisposed to getting infected with various pathogenic agents. The risk factors of infectious diseases related to weak immune system are as follows:

  • Aging process: The older a person gets the more likely he or she to catch any infectious disease. The aging immune response becomes less strong raising the probability of contagious diseases in the elderly. Also, the older people start suffering from chronic or latent infections. The elderly is more prone to skin, urinary tract, and respiratory infections.
  • HIV and AIDS: These severe diseases drastically lower immune function in people and increase susceptibility to infections.
  • Some types of cancer: This life-threatening diseases have a very negative effect on the immune system making people suffer from infections.
  • Medication intake: People who take anticancer medications, immunosuppressive drugs, and steroids are more prone to infectious diseases. But this doesn’t refer to the use of natural HGH supplements.
  • Anti-rejection drug intake: Though the anti-rejection medications decrease the risk of rejection of transplanted organs by the immune system, they also reduce the immune defense against infections.
  • Malnutrition: Poor nutrition provokes body weight drop, exhaustion, and hence loss of the immune system’s ability to resist multiple pathogenic agents. In its turn, infectious disease can further aggravate malnutrition stimulating a more serious invasion by germs.
  • Invasive procedures: The patients who must undergo serious invasive procedures such as organ transplantation, medical device implantation, and different surgeries run a high risk of suffering from infectious complications.
  • No vaccination: Adequate and timely vaccination is the only way to prevent many life-threatening infectious diseases which cause disability and death among the world population. For this reason, it’s extremely crucial not to refuse from the vaccination according to the recommended immunization schedule.
  • Genetic susceptibility: Some people are genetically more predisposed to catch the infections like leprosy, hepatitis B, hepatitis C, malaria, prion disease, tuberculosis, meningococcal disease, dengue, and HIV-1 than other people.
