Critical Thinking Week 7 - Coursework Example

Pathogens are also spread through physical contact with dirty surfaces or even dirty day to day substances such as money, soil, doorknobs, etc. Money is known to be one of the dirtiest substances that people come into contact with on a day to day basis. Pathogens are also found on peoples skins. Individuals are always advised to ensure that they keep their hands clean and surfaces cleaned with an antiseptic to ensure that pathogens are cleared. Pathogens can be introduced into the body through physical touch, through the mouth and even through the air.

Animals are also known to spread germs especially through their skin and hence the need for cleaning from time to time (IOWA State University). The spread of bacteria is very rapid and the only way that individuals can contain it is by ensuring that they wash their hands thoroughly before they eat and also maintaining clean environments around their homes. Direct contact can cause the spread of pathogens, and this can be reduced through the use of condoms, gloves, and masks. However, these are not 100% foolproof as some pathogens are known to pass through the tiny holes that the gadgets have.

Indirect contact with pathogens is more common than direct contact and usually spread very fast. Some of the most common devices include doorknobs that cannot be avoided hence the need for regular disinfecting. Inhalation of the pathogens is perhaps more dangerous than the rest of the ways as it affects the individuals respiratory system, and its effects are more severe. It is advised that sick people avoid coming into contact when they have communicable illnesses, and those that have life-threatening diseases such as tuberculosis should be quarantined until they are no longer in danger.

Pathogens that come from vectors could be avoided through the use of insecticides, which involve killing the vector. The spread of airborne pathogens could be minimized by
