Caused by the microorganisms called viruses, infections pertaining to these microorganisms are known as viral diseases. These diseases are different and diverse in nature as they are caused by a number of viruses. Among them, the common cold is the most known viral disease and occurs due to the infection of your upper respiratory tract, namely the nose and throat.

Other widespread viral infections are:

1. Chickenpox
2. HIV (human immunodeficiency virus)
3. HPV (human papillomavirus)
4. Shingles or herpes zoster (a viral infection that leads to the development of rash)
5. Viral pneumonia (a condition that occurs due to viruses that are responsible for flu and colds)
6. Viral hepatitis (inflammation of the liver that is caused by a virus)
7. Viral meningitis (viral infection wherein inflammation of the membranes that cover the brain occurs)
8. Rubella, mumps and measles
9. Herpes

How do they spread?

These diseases are infectious and can easily spread from one person to another. When the microorganism enters your body, it begins to reproduce.

Different ways that they can spread include:

1. Breathing in the germs present in airborne droplets when an infected person sneezes or coughs
2. Coming in contact with the body fluids of an infected person during sexual activity
3. Indirect contact with these microorganisms when you touched inanimate objects handled by an infected person
4. Viral infections can also spread through insect bites. Certain germs depend on insects as carriers such as ticks and mosquitoes for moving from host to host
5. Having virus-contaminated water or food is another way in which viral infection can spread from person to person. Such a mode of transfer enables the virus to spread among a large number of people. If you wish to discuss about any specific problem, you can consult a General Physician.

Walking is a low intense cardio exercise that is suitable for all age groups. For people with bone problems and back pain, walking is the perfect exercise. It is less stressful on the body and has similar benefits to running or jogging. So if you are looking for reasons to jump on the bandwagon of walking as an exercise, here are a few:

1. Good for the Heart: Running puts some amount of stress on your heart muscles but does not seem to reduce the chances of premature death; whereas walking at a brisk pace puts less stress on the heart and considerably reduces the risk of premature death. Running may also cause inflammation in the muscles of the heart and increases free radicals in the body.
2. Increases immunity: Walking has a beneficial effect on the immune system of the body vis-à-vis running. Running may induce conditions in the body which allow various bacterial infections like cold to foster. You end up falling sick more often if you run.
3. Helps in weight loss: Walking is a steady state exercise resulting in moderate levels of heart rate. Moderate heart rate sustained for 45-60 minutes is advised to lose fat. Running tends to raise the heart rate to drastic levels which cannot be sustained for long, thus leading to reduced fat loss.
4. Stress on the joints: Running is a vigorous activity that places a lot of stress on the knee joints and the lower back. If you have conditions such as osteoarthritis and lower back pain, then running is a strict no for you. It is recommended to walk at a brisk pace for an hour every day for maximum benefits.
5. Walking can be done anywhere: You can take a walk inside your office premises or even walk back to your home after work due to the light nature of the exercise. Running or jogging may require proper gear and may not be suitable for all places.

Excessive sweating or hyperhidrosis occurs due to the presence of extremely sensitive sweat glands in certain body portions. It is a condition in which you sweat more than the normal amount and this can be attributed to temperature, anxiety levels and daily routine.

Symptoms: If the excessive sweating is limited within the underarm, the feet, the face and the palm of your hand, then it is diagnosed as primary focal hyperhidrosis, which is relatively harmless in nature and does not presuppose any serious medical condition. However, excessive sweating might cause severe mental and emotional problem for the affected person. In most of the cases of primary hyperhidrosis, the person suffers from a very early age, but is too embarrassed to check it up by a doctor. Primary hyperhidrosis can also be part-hereditary in nature. However, an early diagnosis might eliminate Primary Hyperhidrosis completely.

But, if excessive sweating occurs at a later stage and all around your body that interrupts your daily schedule, then you should check up with your doctor, as that might be a warning sign for far more serious medical conditions like cancer, malaria, diabetes, heart attack, HIV/AIDS, diabetes, thyroid problems, serious nerve and hormonal anomalies, etc. Also, if you experience excessive sweating at night and that too all of a sudden, you must go for a check-up. This form of Hyperhidrosis, known as Secondary Hyperhidrosis is sometimes accompanied by symptoms of nausea, giddiness in the head, the sudden rise of temperature up to 40 degrees Celsius and an intense pain in the chest.

The immune system of the body essentially plays two important roles. Firstly, it protects the body from bacteria, viruses and other foreign organisms, thus preventing the onset of infections and diseases. Secondly, it ensures that body cells are functioning properly and are not degenerating. Thus, the immune system of the body is quite effective and is responsible for your overall health.

There are times when the immune system becomes weak and is thus unable to fight foreign organisms invading the body. A direct indication that your immune system is weak is when you catch the seasonal cold or flu. In such a case, you have to take certain steps to give a boost to your immune system, such as-

1. Live healthy- Living healthy does not only include eating a balanced diet and exercising regularly. Make sure that you get enough sleep on a daily basis and avoid smoking along with consumption of alcohol. It is also essential that you maintain your weight and keep a tab on your blood pressure.

2. Maintain good hygiene- Hygienic habits such as washing hands before every meal and after using the toilet go a long way when it comes to boosting the immune system.

3. Reduce sugar intake- As per research, it becomes more difficult for white blood cells to fight bacteria when the sugar level of the body is very high, which is why the immune system gets surpassed, and you are more susceptible to infections.

4. Consume healthy fats- Omega-3 and Omega-6 fatty acids play an important role in boosting the immune system. These healthy fats help the immune system to make prostaglandins, which effectively destroy germs and viruses that have invaded the body.

5. Avoid the consumption of toxic food- As far as possible, make sure that you are consuming organic food. This is because food grown on a commercial scale is full of toxic chemicals from the pesticides, insecticides, preservatives and artificial colours added to it. The toxic chemicals have a grave impact on the immune system of the body, which can lead to severe complications in the long run.

Although, you want your immune system to be strong and effective, make sure that it is not highly overactive. A highly overactive immune system can also lead to many health complications, such as the onset of autoimmune conditions. All in all, make sure that you are leading a healthy and balanced lifestyle. If you wish to discuss about any specific problem, you can consult a doctor and ask a free question.

Although your body is already in possession of the bacteria leading to tuberculosis, your immune system is able to prevent you from becoming sick. Doctors have made a distinction between latent and active tuberculosis (TB). In case of latent TB, the bacteria in the body in a passive state and it causes no symptoms, and therefore it is not contagious. But, in the case of active TB, you would become sick and may even spread the disease to others. It can take place in the first few weeks or even after several months of being infected with TB bacteria.

What are the symptoms of active TB?

1. If you are coughing for over three weeks and sometimes even coughing up blood, it can be a sign of TB.
2. Chest pain and pain while coughing and breathing along with fatigue, fever, chills and night sweat are the common symptoms of TB along with loss of appetite and unintentional weight loss. TB may even affect other organs of your body, including your brain, spine and kidneys.
3. When TB takes place outside the lungs, then the signs of TB can vary as per the organs that are involved. For instance, TB in the spine can cause back pain and that in kidneys may cause blood in the urine.

What are the causes of TB?
TB is caused by a bacteria which spreads from individual to individual via the microscopic droplets that are released into the air. This may happen when an affected person is left untreated and he speaks or sneezes or coughs or laughs.

Though the disease is contagious, it is not easy to be affected by it. As a result, you are much more likely to get affected with active tuberculosis from a person you live with or come in regular contact with, rather than a stranger. It is important to note here that people who are affected with TB and going through proper medications for over two weeks are no more contagious.

Right from the 1980s, the number of individuals affected with TB has increased dramatically, owing to the spread of HIV, which is the virus known for causing AIDS. A person infected with HIV has a weak immunity system as a result of which it becomes difficult for the body to deal with TB bacteria. So those who have AIDS are more likely to be affected with active TB and sometimes the latent form also progresses to an active one very quickly. Therefore, it is important to seek medical assistance and detect if you have any such health complications concerning TB. If you wish to discuss about any specific problem, you can consult a General Physician.

Type 2 diabetes (T2DM) is a chronic metabolic disorder that prevents the body from processing sugar or glucose. The disorder causes insufficient production of the hormone Insulin (responsible for regulating sugar into the different parts of your body); or the body's failure to respond to the hormone produced. Although no cure is available for T2DM, there are several ways in which you can help prevent Type 2 diabetes in your child. These are:

1. Get your child to indulge in some physical activity - Spending about 60 minutes of the day on physical activity can help your child to ward off Type 2 diabetes. In terms of screen time, it shouldn't be over 2 hours a day. By doing so, he or she ends up building his or her muscles as well as gets rid of extra fat from the body. An active life would also help your child to maintain an optimal body weight with obesity being a cause of this form of diabetes. Whether it's a sport like swimming, cricket or basketball, or even walking and dancing, physical activity in any form can help in preventing your child from developing Type 2 diabetes.

2. Plan a well-balanced diet for your child - Encouraging your child to have healthy foods and making right food choices can also lower his or her chances of getting this metabolic disorder. Foods high in fiber like whole grain cereals and bread, lentils, fruits, and vegetables should be consumed. Similarly, foods low in trans and saturated fats like lean meat, chicken, yogurt and cheese should be included in your child's diet. Processed foods, as well as sugary drinks, should be no-no when it comes to your child's diet.
