Tuberculosis (TB)
About the Disease
Tuberculosis is an infectious disease caused by the bacterium Mycobacterium tuberculosis. It primarily affects the lungs, but can also affect other parts of the body. It spreads through the air when an infected person coughs, sneezes, or speaks.
Symptoms
- Persistent cough (more than 2 weeks)
- Coughing up blood
- Chest pain
- Weakness or fatigue
- Weight loss
- Loss of appetite
- Fever
- Night sweats
Prevention
- Getting the BCG vaccine
- Staying away from infected people
- Living in well-ventilated rooms
- Eating a healthy diet
- Avoiding smoking
- Getting regular check-ups
Treatment
Treatment for tuberculosis requires a 6–9 month course of antibiotics. The most common medications are:
- Isoniazid
- Rifampicin
- Ethambutol
- Pyrazinamide
Completing the full course of treatment is extremely important, otherwise drug-resistant tuberculosis can develop.
Diabetes
About the Disease
Diabetes is a chronic disease in which the body cannot produce enough insulin or cannot use insulin effectively. Insulin is a hormone that regulates blood sugar. There are mainly two types of diabetes: Type 1 and Type 2.
Symptoms
- Frequent urination
- Excessive thirst
- Increased hunger
- Unexpected weight loss
- Fatigue
- Blurred vision
- Slow-healing wounds
- Frequent infections
Prevention
- Regular exercise
- Eating a healthy diet
- Maintaining a healthy weight
- Avoiding smoking
- Limiting alcohol consumption
- Regular blood sugar checks
Treatment
Treatment for diabetes varies by type:
- Type 1 diabetes: Insulin injections, diet control, regular exercise
- Type 2 diabetes: Lifestyle changes, oral medications (metformin, sulfonylureas), insulin if required
Diabetes is managed through a combination of diet, exercise, and medication.
Malaria
About the Disease
Malaria is a serious infectious disease caused by the Plasmodium parasite. It is spread through the bite of infected mosquitoes. Millions of people worldwide are affected by this disease every year.
Symptoms
- High fever and chills
- Sweating
- Headache
- Nausea and vomiting
- Muscle pain
- Fatigue
- Cough
- Abdominal pain
Prevention
- Using mosquito nets
- Applying mosquito repellent cream
- Wearing full-sleeved clothing
- Eliminating mosquito breeding sites
- Taking anti-malarial medication (for travel)
- Using mosquito repellents at home
Treatment
Treatment for malaria depends on the type of parasite:
- Chloroquine
- Artemisinin-based Combination Therapy (ACT)
- Mefloquine
- Doxycycline
It is important to start treatment immediately once malaria is diagnosed, especially in severe cases of malaria.
Dengue
About the Disease
Dengue is a viral disease spread by the Aedes aegypti mosquito. It is mainly found in tropical and subtropical regions. There are four types of dengue virus, and the risk of severe dengue increases if a person is infected with more than one type.
Symptoms
- Sudden high fever (104°F/40°C)
- Severe headache
- Pain behind the eyes
- Muscle and joint pain
- Skin rash
- Nausea and vomiting
- Bleeding (from nose, gums)
- Fatigue
Prevention
- Protecting against mosquitoes (nets, repellent cream)
- Wearing full-sleeved clothing
- Eliminating mosquito breeding sites
- Removing stagnant water
- Using mosquito repellents at home
- Taking special precautions during the monsoon
Treatment
There is no specific treatment for dengue; treatment is based on symptoms:
- Drinking plenty of fluids
- Taking paracetamol (for fever and pain)
- Resting
- Regular monitoring of blood platelet count
- Hospitalization in severe cases
Medicines like aspirin and ibuprofen should be avoided as they can increase bleeding.
Typhoid
About the Disease
Typhoid is an infectious disease caused by the bacterium Salmonella typhi. It is mainly spread through contaminated food and water. This disease is more common in developing countries where there is a lack of sanitation and clean water.
Symptoms
- Sustained high fever (103°F/39°C)
- Headache
- Abdominal pain
- Weakness and fatigue
- Loss of appetite
- Pink rash on skin (rose spots)
- Constipation or diarrhea
- Dry cough
Prevention
- Getting the typhoid vaccine
- Drinking clean water (boiled or purified)
- Eating well-cooked food
- Washing fruits and vegetables before eating
- Washing hands regularly
- Avoiding street food
- Maintaining hygiene
Treatment
Typhoid is treated with antibiotics:
- Ciprofloxacin
- Ceftriaxone
- Azithromycin
- Chloramphenicol
Drinking plenty of fluids and resting is important. Hospitalization may be necessary in severe cases.
Pneumonia
About the Disease
Pneumonia is a lung infection that can be caused by bacteria, viruses, or fungi. Fluid accumulates in the air sacs of the lungs, making it difficult to breathe. This disease can occur at any age, but infants and elderly people are at higher risk.
Symptoms
- Cough (with phlegm)
- Fever, chills
- Difficulty breathing
- Chest pain
- Fatigue
- Nausea, vomiting
- Loss of appetite
- Confusion (especially in elderly people)
Prevention
- Getting the pneumococcal vaccine
- Getting the flu vaccine
- Avoiding smoking
- Washing hands regularly
- Eating a healthy diet
- Regular exercise
- Getting adequate rest
Treatment
Treatment for pneumonia varies by cause:
- Bacterial pneumonia: Antibiotics (amoxicillin, azithromycin)
- Viral pneumonia: Antiviral medication, symptom-based treatment
- Fungal pneumonia: Antifungal medication
Drinking plenty of fluids, resting, and taking paracetamol to reduce fever are important. Oxygen therapy and hospitalization may be necessary in severe cases.
Hepatitis
About the Disease
Hepatitis is inflammation of the liver that can be caused by viruses, alcohol, medications, or autoimmune conditions. Viral hepatitis has several types: A, B, C, D, and E. Each type spreads differently and has a different treatment.
Symptoms
- Fatigue
- Nausea and vomiting
- Abdominal pain
- Yellowing of skin and eyes (jaundice)
- Dark urine
- Pale stools
- Joint pain
- Loss of appetite
Prevention
- Getting vaccinated for Hepatitis A and B
- Practicing safe sex
- Avoiding sharing needles
- Washing hands regularly
- Drinking clean water
- Eating well-cooked food
- Limiting alcohol consumption
- Maintaining hygiene during tattoos and piercings
Treatment
Treatment for hepatitis varies by type:
- Hepatitis A: No specific treatment; rest and fluids are important
- Hepatitis B: Antiviral medication (entecavir, tenofovir)
- Hepatitis C: Antiviral medication
- Hepatitis D: Interferon alpha
- Hepatitis E: No specific treatment; rest and fluids are important
Avoiding alcohol, eating a healthy diet, and regular check-ups with a doctor are important.
COVID-19
About the Disease
COVID-19 is a respiratory disease caused by the SARS-CoV-2 virus. It mainly spreads through droplets released when an infected person breathes, coughs, or talks. Since the global pandemic began in late 2019, it has claimed millions of lives.

Treatment
Treatment for COVID-19 varies based on the severity of symptoms:
- Mild symptoms: Rest, plenty of fluids, paracetamol
- Moderate symptoms: Oxygen therapy, antiviral medication (remdesivir)
- Severe symptoms: Ventilator support, steroids (dexamethasone), immunomodulators
Some people may experience long-term symptoms (long COVID) after COVID-19, which may require special treatment.
