Not only are new viruses appearing daily, but some of the old viruses are getting smarter and morphing. Your skin acts as a natural barrier against infections, but some viruses have found different paths to get into your body and can cause a serious spread of infectious diseases.
“Super Bugs” have also learned how to produce compounds that can make our current antibiotic defenses useless against them. Infectious diseases are caused by types of bacteria, viruses, parasites, and fungi around us.
It’s important to understand how these diseases are transmitted. If you understand the transmission process, you can use this knowledge to protect yourself and help prevent the spread of illnesses.
Infectious diseases are caused by microorganisms such as viruses, bacteria, fungi, or parasites and can spread between individuals and/or animals. Infectious diseases are transmitted from person to person by direct or indirect contact. Certain types of microorganisms can cause infectious diseases. Basically, they can be caught and spread very easily and should be treated with concern.
An infectious disease is basically an infection in the body from a microorganism entering through an exterior source. For bacteria or fungi, this means dividing and growing new cells at a very fast rate. On the other hand, viruses are similar to infections but have an extra layer of attack through entering the cells and taking over their control centers.
This allows them to multiply and spread quickly, often before being detected.
The easiest way to prevent the spread of infectious diseases is to not pick up germs at all. Unfortunately, this is quite impossible to avoid in public. Keeping germs at bay is an easier solution, and this can be done by taking precautions. Preventing infection before it begins to spread is crucial, and avoid spreading it to others at all costs. There are global methods of detection and prevention set in place to stop the spread of infectious diseases.
But you can personally take steps to prevent these diseases:
Within the next 100 years, the world's population is expected to rise above 11 billion, creating a rise in food demand globally. The increase in population and demand for food will ultimately, give rise to new types of human infectious diseases.
Many researchers believe that these will be "two of the most formidable ecological and public health challenges of the 21st century."
Developing countries are at a greater risk for infectious diseases and are commonly the most impacted. This will only increase as populations and food scarcities rise.
Lack of funding and research will only propel this problem further. However, the same can be said for most countries. Lack of financial resources, training, and proper equipment present constant challenges to scientists globally. It should also be mentioned that social, and political constraints play significant roles in further research funding in most countries also.
However, one of the main problems when it comes to research of these infectious diseases is the general lack of immediate concern. All these diseases have the potential to morph into a global pandemic at any moment. With the constant changing state of infectious disease, a pandemic can begin and spread extremely quickly, being prepared in the event of that situation will give us an advantage. Yet, little funding is received on the spread of infectious diseases because they are not viewed as immediate threats to public health.
