What factors affect disease spread?

Responsible factors include ecological changes, such as those due to agricultural or economic development or to anomalies in climate; human demographic changes and behavior; travel and commerce; technology and industry; microbial adaptation and change; and breakdown of public health measures.

What are the 5 methods of disease transmission?

The transmission of microorganisms can be divided into the following five main routes: direct contact, fomites, aerosol (airborne), oral (ingestion), and vectorborne. Some microorganisms can be transmitted by more than one route.

How can we limit the spread of disease?

Prevent the spread of infectious disease

1. Immunise against infectious diseases.
2. Wash and dry your hands regularly and well.
3. Stay at home if you are sick.
4. Cover coughs and sneezes.
5. Clean surfaces regularly.

Communicable diseases, also known as infectious diseases or transmissible diseases, are illnesses that result from the infection, presence and growth of pathogenic (capable of causing disease) biologic agents in an individual human or other animal host.

What diseases are caused by environmental factors?

There are many different types of environmental disease including: Disease caused by physical factors in the environment, such as skin cancer caused by excessive exposure to ultraviolet radiation in sunlight. Disease caused by exposure to toxic or irritant chemicals in the environment such as toxic metals.

What are the main factors that affect climate?

Factors that Influence Climate

• Elevation or Altitude effect climate. Normally, climatic conditions become colder as altitude increases.
• Prevailing global wind patterns.
• Topography.
• Effects of Geography.
• Surface of the Earth.
• Climate change over time.

What are the 8 modes of transmission?

Modes of transmission

• Direct. Direct contact. Droplet spread.
• Indirect. Airborne. Vehicleborne. Vectorborne (mechanical or biologic)

What are the common methods of transmission of diseases Class 9?

For example:

• Airborne transmission. Some infectious agents can travel long distances and remain suspended in the air for an extended period of time.
• Contaminated objects.
• Food and drinking water.
• Animal-to-person contact.
• Animal reservoirs.
• Insect bites (vector-borne disease)
• Environmental reservoirs.

Is mode of transmission by kissing?

Kissing offers many health benefits, but may also transmit a small number of disease-causing bacteria and viruses. Bacteria and viruses in the saliva or blood of one person can be spread to another person by kissing. Some diseases are more easily spread than others.

How could the spread of tuberculosis be reduced or prevented?

The risk of infection can be reduced by using a few simple precautions: good ventilation: as TB can remain suspended in the air for several hours with no ventilation. natural light: UV light kills off TB bacteria. good hygiene: covering the mouth and nose when coughing or sneezing reduces the spread of TB bacteria.
