What are the 4 ways in which infectious diseases are spread?
Germs can spread from person to person through:
- the air as droplets or aerosol particles.
- faecal-oral spread.
- blood or other body fluids.
- skin or mucous membrane contact.
- sexual contact.
How do infectious diseases affect the economy?
The economic costs of infectious diseases—especially HIV/AIDS and malaria—are significant. Their increasing toll on productivity owing to deaths and chronic debilitating illnesses, reduced profitability and decreased foreign investment, has had a serious effect on the economic growth of some poor countries.
What is the relationship between infection and disease?
Infection, often the first step, occurs when bacteria, viruses or other microbes that cause disease enter your body and begin to multiply. Disease occurs when the cells in your body are damaged — as a result of the infection — and signs and symptoms of an illness appear.
How might disease be connected to the economy of a country?
Disease may cause economic loss in feedlots through mortality, treatment cost, or effects on productivity. The impact of clinical and subclinical disease on production efficiency and economic returns may be greater than the losses associated with mortality.
How can coronavirus spread?
How does the virus spread? COVID-19 spreads when an infected person breathes out droplets and very small particles that contain the virus. These droplets and particles can be breathed in by other people or land on their eyes, noses, or mouth. In some circumstances, they may contaminate surfaces they touch.
What are the 3 main ways infection can get into the body?
Pathogens can enter the body by coming into contact with broken skin, being breathed in or eaten, coming into contact with the eyes, nose and mouth or, for example when needles or catheters are inserted.
How do infectious diseases affect health?
Most infectious diseases have only minor complications. But some infections — such as pneumonia, AIDS and meningitis — can become life-threatening. A few types of infections have been linked to a long-term increased risk of cancer: Human papillomavirus is linked to cervical cancer.
What are effects of pandemic?
The economic and social disruption caused by the pandemic is devastating: tens of millions of people are at risk of falling into extreme poverty, while the number of undernourished people, currently estimated at nearly 690 million, could increase by up to 132 million by the end of the year.
How do you know if your body is fighting a virus?
A sore, scratchy throat signals that white blood cells and antibodies are rushing to the area to fight infection – causing inflammation and irritation. A sore throat that just won't quit is usually a good indication that your body is fighting a virus and may need a little bit more tender loving care than usual.
What body processes are affected by infection?
In response to infection, your immune system springs into action. White blood cells, antibodies, and other mechanisms go to work to rid your body of the foreign invader.
How does the spread of infectious diseases affect the economy?
Infectious diseases can lock people into poverty, undermine the resilience of communities, and have devastating consequences for a country’s economy. Globally the incidence of infectious diseases has declined since 2000, but they continue to have major health and economic costs.
Why was the spread of cholera an economic risk?
In the eyes of colonial health officials and the drafters of the first International Sanitary Conventions, the spread of cholera and plague was an economic, epidemic, and political risk to the long-term stability of the global economy.
How did epidemics affect the control of disease?
The threat of diseases emerging from colonial sites that could disturb systems of trade and travel led to aggressive control of these diseases in sites of epidemic outbreak and aggressive scrutiny of those people deemed to be responsible for disease spread.
What are the linkages between globalization and infectious diseases?
