10 Germs on Body | Bacteria


Germs, also known as microorganisms or microbes, are tiny living organisms that are too small to be seen with the naked eye. They can exist in various forms, including bacteria, viruses, fungi, and protozoa. Germs are found everywhere in our environment, including on surfaces, in the air, and even inside our bodies.

While many germs are harmless and some are even beneficial, others can cause diseases and infections. Bacteria are single-celled organisms that can multiply rapidly and cause infections such as strep throat, urinary tract infections, and pneumonia. Viruses are smaller than bacteria and require a host cell to replicate. They can cause illnesses such as the common cold, influenza, and COVID-19. Fungi, such as molds and yeasts, can cause infections like athlete’s foot and thrush. Protozoa are single-celled organisms that can cause diseases like malaria and giardiasis.

Germs can be transmitted through various means, including direct contact with an infected person, contact with contaminated surfaces or objects, and through respiratory droplets when an infected person coughs or sneezes. Proper hygiene practices such as regular handwashing, covering the mouth and nose when coughing or sneezing, and disinfecting surfaces can help reduce the spread of germs.

It’s important to note that the human body also contains a vast number of microbes, known as the human microbiota, which play a crucial role in maintaining our overall health and well-being. These beneficial microbes help with digestion, immune function, and other physiological processes.

How Germs Enter the Body

Germs can enter the body through various routes. Here are some common ways germs can enter the body:

  1. Respiratory Route: Many germs, especially viruses and bacteria, can enter the body through the respiratory system. This occurs when an infected person coughs, sneezes, talks, or even breathes, releasing respiratory droplets containing germs into the air. When a healthy person inhales these droplets, the germs can enter their respiratory tract and cause infection. Examples include the flu virus, common cold viruses, and bacteria causing respiratory infections like tuberculosis.
  2. Oral Route: Germs can enter the body through the mouth when contaminated food, water, or objects are ingested. Consuming food or beverages that are contaminated with harmful bacteria, viruses, or parasites can lead to gastrointestinal infections such as food poisoning or gastroenteritis. Poor hand hygiene, like not washing hands after using the restroom, can also allow germs to be transferred to the mouth.
  3. Direct Contact: Germs can enter the body through direct contact with infected individuals or contaminated surfaces. When you touch an infected person, shake hands, or come into contact with surfaces or objects that have been touched or contaminated by germs, you can transfer the germs to your own body. Examples include skin infections like impetigo or wound infections caused by bacteria.
  4. Vector-Borne: Certain germs, such as those causing diseases like malaria, dengue fever, or Lyme disease, are transmitted to humans through vectors like mosquitoes, ticks, or other biting insects. These vectors act as carriers, transmitting the germs from an infected source to a new host.
  5. Sexual Contact: Some germs, like certain types of bacteria and viruses, can be transmitted through sexual contact. Sexually transmitted infections (STIs) such as chlamydia, gonorrhea, syphilis, and human papillomavirus (HPV) are examples of infections that can be contracted through sexual activity.

It’s important to note that the body has various defense mechanisms, such as the immune system, that work to fight off germs and prevent infections. However, practicing good hygiene, such as regular handwashing, maintaining a clean environment, and following safe food handling practices, can help reduce the risk of germs entering the body and causing infections.


Precaution to Prevent Germs

To prevent the spread of germs and reduce the risk of infections, it’s important to practice good hygiene and follow certain precautions. Here are some general precautions to consider:

  1. Regular Handwashing: Wash your hands frequently with soap and water for at least 20 seconds, especially before eating, after using the restroom, after coughing or sneezing, and after touching surfaces in public places. If soap and water are not available, use an alcohol-based hand sanitizer.
  2. Proper Respiratory Etiquette: Cover your mouth and nose with a tissue or your elbow when coughing or sneezing to prevent the release of respiratory droplets containing germs into the air. Dispose of used tissues properly and wash your hands afterward.
  3. Avoid Touching Your Face: Try to avoid touching your face, especially your eyes, nose, and mouth, as these are common entry points for germs. Touching contaminated surfaces and then touching your face can increase the risk of infection.
  4. Vaccinations: Stay up to date with recommended vaccinations to protect yourself and others from vaccine-preventable diseases. Vaccinations can significantly reduce the risk of contracting and spreading infectious diseases caused by bacteria and viruses.
  5. Maintain Clean Environments: Regularly clean and disinfect frequently-touched surfaces and objects, such as doorknobs, light switches, keyboards, and mobile phones. Use appropriate disinfectants to kill germs and prevent their spread.
  6. Practice Safe Food Handling: Follow proper food safety measures, such as washing hands before handling food, cooking food to appropriate temperatures, avoiding cross-contamination between raw and cooked foods, and storing food properly.
  7. Stay Home When Sick: If you are feeling unwell, especially with symptoms such as fever, cough, or cold, it’s important to stay home and avoid close contact with others. This helps prevent the spread of germs to individuals who may be more vulnerable to infections.
  8. Maintain a Healthy Lifestyle: Taking care of your overall health can help strengthen your immune system and reduce the risk of infections. Get enough sleep, eat a balanced diet, engage in regular physical activity, manage stress, and avoid smoking or excessive alcohol consumption.

Remember that these precautions are general guidelines. The specific precautions you should take may vary depending on the type of germ or infection you are concerned about. It’s always a good idea to follow the recommendations of healthcare professionals and public health authorities for specific guidance in your region or for particular situations.

Precaution when not well

When you’re not feeling well, it’s important to provide your body with the right nourishment to support your recovery. While individual dietary needs may vary depending on the specific illness or condition, here are some general dietary recommendations to consider:

  1. Stay Hydrated: Drink plenty of fluids, such as water, herbal tea, clear broths, or electrolyte-replenishing drinks, to prevent dehydration. Proper hydration helps loosen congestion, soothes a sore throat, and supports overall bodily functions.
  2. Eat Nutrient-Dense Foods: Focus on consuming nutrient-rich foods that can provide essential vitamins, minerals, and antioxidants to support your immune system. Include a variety of fruits, vegetables, whole grains, lean proteins, and healthy fats in your diet.
  3. Consume Adequate Protein: Protein is important for tissue repair and immune function. Include sources of lean protein such as chicken, fish, eggs, legumes, and tofu in your meals to support your recovery.
  4. Incorporate Fruits and Vegetables: Fruits and vegetables are packed with vitamins, minerals, and antioxidants that can help boost your immune system. Aim to include a variety of colorful fruits and vegetables in your diet to obtain a range of beneficial nutrients.
  5. Opt for Easy-to-Digest Foods: When you’re not feeling well, it may be helpful to choose foods that are easy to digest. These may include soups, broths, cooked vegetables, soft fruits, and well-cooked grains. Avoid heavy, greasy, or spicy foods that may exacerbate digestive discomfort.
  6. Consider Probiotic-Rich Foods: Probiotics are beneficial bacteria that can support gut health and overall immunity. Include foods like yogurt, kefir, sauerkraut, and kimchi, which are rich in probiotics, to help replenish and maintain a healthy gut microbiome.
  7. Avoid or Limit Sugary Foods and Drinks: High sugar intake can suppress the immune system and exacerbate inflammation. Try to minimize consumption of sugary beverages, processed snacks, and desserts while you’re unwell.
  8. Listen to Your Body: Pay attention to your appetite and eat when you feel hungry. If you have a reduced appetite, try eating small, frequent meals or snacks throughout the day to ensure you’re getting adequate nutrition.

It’s important to note that these dietary recommendations are general in nature and may not be suitable for everyone or every condition. If you have specific dietary restrictions, allergies, or concerns, it’s best to consult with a healthcare professional or registered dietitian for personalized advice tailored to your needs.

Remember to eat only fresh vegetables and seasonal fruits that we get directly from mother earth. 

However, in order to avoid the fruit’s negative effects, it is always best to consume it in moderation. Nothing in excessive amounts is healthy for our health.
