GENERAL KNOWLEDGE

Detailed explanation-1: -Noncommunicable diseases like heart disease, asthma, cancer and diabetes are made worse by unhealthy living and working conditions, inadequate green space, pollution such as noise, water and soil contamination, urban heat islands and a lack of space for walking, cycling and active living.

Detailed explanation-2: -Spreading Diseases The introduction of new immigrants and the growth of large urban areas allowed previously localized diseases to spread quickly and infect larger populations. Towns grew into cities as industrialization sparked urban migration from rural communities in both the United States and Europe.

Detailed explanation-3: -The impact of this varies from one region to another. Resource poor countries suffer the most due to an already high disease burden, poor infrastructures, lack of clean, potable water and sanitation, as well as an acute shortage of qualified health personnel to manage, control and contain the crisis/spread.
