In the vibrant city of Bangalore, where technology meets tradition, the health landscape is as diverse as its culture. Children heading to school, people rushing to offices, and street vendors setting up their stalls are the typical mornings in the city. Amidst the hustle, people’s unseen health problems shape the city’s health landscape.
Meet Shobha, a street vendor who visits the hospital with joint pain and a high fever and gets diagnosed with dengue, a mosquito-borne disease. On the other part of the city, Rahul, a software engineer, faces a different battle. With busy, stressful working days and a sedentary lifestyle, he is caught in the web of lifestyle diseases like hypertension and diabetes. Both stories reflect the city’s inadequate sanitation, rapid urbanisation, and tech-driven culture that make residents vulnerable to many illnesses, both communicable and non-communicable diseases. Let us look at the common health challenges in the garden city of Bangalore.
What are Communicable Diseases?
Communicable diseases are illnesses caused by infectious agents like viruses, bacteria, fungi, or parasites that can spread from one person to another, either directly or indirectly. These diseases can be transmitted through various means, including physical contact, respiratory droplets, insect bites, or contaminated water or food. Examples include dengue, influenza, tuberculosis, and more.
Most Common Communicable Diseases in Bangalore
Bangalore faces the challenge of several infectious diseases due to rapid urbanisation, dense population, and climate. Below are some of the most common communicable diseases in the city:
1. Tuberculosis
TB remains a significant health challenge not just in Bangalore but countrywide. TB spreads through airborne droplets when an infected person coughs or sneezes.
According to the India Tuberculosis Report, 2023, Karnataka has reported 80,416 TB cases, with Bangalore contributing a substantial share.
2. Dengue
Dengue fever is highly prevalent in Bangalore, especially during the monsoon season through the Aedes mosquito, which breeds in stagnant water.
In 2023, Karnataka had reported over 19,300 dengue cases, where 50% cases are from Bangalore. The state has already crossed the caseload of 19,000 this year.
3. Malaria
Malaria is a major issue in certain parts of Bangalore despite the taken measures. Malaria is spread through the bite of infected Anopheles mosquitoes.
According to the National Vector Borne Disease Control Programme (NVBDCP), the city has reported around 400-700 cases of malaria every year for the past few years.
4. H1N1 Influenza
Bangalore has experienced several outbreaks of influenza cases in recent years. The virus spreads through respiratory droplets when an infected person coughs or sneezes.
There are 991 cases reported this year in the state, especially more during monsoon season.
5. Gastrointestinal Infections
Waterborne diseases like typhoid, cholera, and hepatitis A are common, particularly in areas with poor sanitation. The city reported several hundred cases of typhoid and cholera annually, particularly during the monsoon.
Factors Leading to Communicable Diseases in Bangalore
The prevalence of common diseases in Bangalore is influenced by various factors mentioned below:
1. Rapid Urbanisation
Bangalore's rapid urbanisation has led to high population density and inadequate housing with poor ventilation in low-income areas. This has increased the risk of airborne diseases like tuberculosis (TB) and influenza.
2. Poor Sanitation
Stagnant water during monsoon and poor sanitation infrastructure make it a breeding ground for mosquitoes to spread vector-borne and waterborne diseases.
3. Climate Change
Variations in temperature and humidity also influence the spread of respiratory infections like H1N1 influenza. High levels of air pollution in Bangalore also make people more susceptible to infections like TB and respiratory viruses.
4. Travel-related Disease Spread
The city attracts large numbers of migrants from various places, which increases the risk of new infections due to the frequent movement of the population.
5. Lack of Awareness
A lack of awareness about preventive measures and inadequate vector control measures also contribute to the continued spread of communicable diseases.
Tips to Prevent Communicable Diseases in Bangalore
Here are some practical tips to prevent communicable diseases in Bangalore:
1. Practice Personal Hygiene
Follow basic hygiene like wash your hands regularly with soap and water. Cover your mouth and nose while coughing or sneezing.
2. Safety Measures for Mosquito Control
Regularly eliminate stagnant water from flower pots and other places to control mosquito breeding. Also, use mosquito repellents and nets to avoid bites especially in rainy season.
3. Safe Food and Water
Ensure to drink boiled or filtered water. Avoid street food or food from unhygienic sources. This helps in preventing waterborne diseases like cholera and typhoid.
4. Avoid Over-Crowded Areas
Use masks in public places and avoid crowded places, especially during outbreaks of seasonal flu and other communicable diseases.
5. Keep Your Environment Clean
Regular cleaning and proper waste disposal help prevent the spread of many diseases.
6. Get Vaccinated
Ensure you and your family are up-to-date with seasonal flu and preventable infection vaccinations.
7. Seek Medical Help
Seek early medical treatment as soon as you experience the symptoms to avoid complications and transmission to others.
8. Support Public Health Initiatives
Engage in local health campaigns and encourage efforts by the government and NGOs to improve healthcare infrastructure and sanitation.

This city’s health landscape experiences a number of non-communicable diseases, prevalence of which can’t be ignored at all. However, before going deeper, let’s understand-
What actually are non-communicable diseases?
Let us explain!
Non-communicable diseases are chronic health conditions that are not transmitted from person to person. They often result from a combination of physiological, genetic, environmental, and behavioural factors and require ongoing health management rather than a cure. As mentioned Bangalore has become a hub for non-communicable diseases as well, We’ve complied the below list for you.
Most Common Non-Communicable Diseases in Bangalore
Below are non-communicable diseases in Bangalore that are a significant public health concern:
1. Cardiovascular Diseases
Cardiovascular diseases, including hypertension, stroke, and coronary artery disease, are among the leading causes of mortality in Bangalore. One in three people in Karnataka has hypertension, as per the Indian Council of Medical Research (ICMR) study. The prevalence of hypertension in urban areas like Bangalore is estimated to be around 25-30% among adults.
2. Diabetes
Diabetes, particularly type 2 diabetes, is highly prevalent in Bangalore due to lifestyle factors. The Indian Council of Medical Research (ICMR) reported that one in ten adults is diabetic in Karnataka.
3. Chronic Respiratory Diseases
Respiratory conditions like Chronic Obstructive Pulmonary Disease (COPD) and asthma, influenced by air pollution and smoking, are common in Bangalore. As per the National Institute of Health, the prevalence of COPD in urban Karnataka, including Bangalore, is estimated to be around 5% among adults.
4. Cancer
Incidence of various cancers, including lung, breast, cervical, and oral cancers, are on the rise in Bangalore. The Bangalore Cancer Registry reports that breast cancer is the most common cancer among women, with an incidence rate of about 30-35 per 100,000 women.

Mental health issues such as depression, anxiety, and stress-related disorders are increasingly recognised as major health concerns in Bangalore. NIMHANS, based in Bangalore, estimates that approximately 12-15% of people suffer from some form of mental health disorder, with depression being particularly prevalent.
Reasons for Rise in Non-Communicable Diseases in Bangalore
The below factors influence the high prevalence of non-communicable diseases (NCDs) in Bangalore:
Sedentary Lifestyle
People with an inactive lifestyle or no work-life balance are prone to lifestyle diseases like obesity, cardiovascular diseases, and diabetes. Tobacco use, alcohol consumption, and high pollution increase the risk of many diseases.
Inadequate Diet

In metro cities like Bangalore where there are ample food options, people tend to consume more processed, unhealthy or street foods and unknowingly welcome lifestyle diseases.
Stress
This chronic stress is the root cause of many physical and mental health disorders like depression and anxiety. Stress triggers like bumper to bumper traffic and long working hours in Bangalore city contribute to mental disorders.
Genetic Factors
Family history of hypertension, diabetes, and cancer also plays a role in the prevalence of non-communicable diseases.
Lack of Awareness
Lack of awareness and inadequate preventive measures lead to delayed diagnosis and treatment.
