How to prevent infectious diseases


Definition of infectious disease


Infectious disease is a kind of disease caused by various pathogens that can be transmitted from person to person, animal to animal or human to animal. Most of the pathogens are microorganisms, a small number of parasites, parasites caused by the people also called parasitic diseases. An infectious disease is an infectious disease that spreads widely from person to person or from person to animal, and is transmitted to another person or species by various means.


How to prevent infectious diseases


The prevention of infectious diseases should be managed from the following three aspects:


1.Control the source of infection


Controlling the source of infection is fundamental to preventing infectious diseases. When a few microbe and parasite invade the human body, the meeting is latent in the human body unceasing reproduction, wait for the reproduction quantity to reach a certain degree after meeting sick hair, and these germ still can pass a person’s saliva, semen, blood, excrement wait for a variety of ways to infect others. Therefore, first of all, we need to control the source of infection. When people are found to be infected with infectious diseases, they should be isolated and treated in time. Meanwhile, infectious secretions, faeces and daily supplies should be thoroughly disinfected to prevent the spread of pathogens through these channels. If animals are the source of infection, timely and efficient measures should be taken to ensure that the source of infection will not continue to spread the pathogen to susceptible people.


2.Route of transmission


Every kind of infectious disease has its way of transmission, and different types of infectious disease are also different. The common ways of transmission are blood transmission, secretions transmission, excreta transmission, etc. In order to prevent infectious disease, it is necessary to cut off its way of transmission in time. For sexually transmitted diseases, sexual life should be prohibited, sexual knowledge should be popularized, healthy sexual life should be advocated, and condom use should be publicized and educated for high-risk sexual behaviors. For the bird flu infectious diseases to improve resistance, while paying attention to daily hygiene, wash hands frequently, usually go out to wear a mask, meat to be cooked, but also with the bird flu patients isolation;


3.Protect vulnerable groups


Infectious disease is in favor of low resistance, especially the elderly, children, pregnant women are infectious diseases to attack object first, so these people should attach importance to protect themselves, especially often exercise, eat more nutritious food, improve the body’s nonspecific immunity, when necessary, also can take temporary isolation of vulnerable groups.


Transmission routes of infectious diseases


1.Airborne infection


Some pathogens can spread freely in the air, usually 5 microns in diameter, can float in the air for a long time, do long distance movement, mainly by respiratory system infection, sometimes also mixed with droplet infection.


2.Droplet infection


Droplet infection is the main route of transmission, many original infection by patients when they cough, sneeze, talk, jet droplets of warm and humid, adhere to the pathogen, along with the air turbulence, short floating in the wind away for short periods of time, by a host for breathing, the mouth or eyes accidentally touch the surface adhesion, cause new infected host. Examples: bacterial meningitis, chicken pox, common cold, influenza, mumps, tuberculosis, measles, German measles, whooping cough and so on. Due to the small size and quantity of droplet, it is difficult to carry heavy pathogens, so the parasitic infection hardly infects other individuals by this way.


infectious diseases


3.Fecal-oral infection


Infectious diseases can be transmitted through direct contact with infected individuals, bodily fluids and excreta of infected persons, and objects contaminated by infected persons. They can be transmitted through air, water, food, contact, soil, vertical transmission (mother-to-child transmission), bodily fluids, fecal-oral transmission, etc.


4.Contact infection


The way of transmission through direct touch is called contact transmission. In addition to direct touching and kissing patients, this kind of disease can also be transmitted by sharing personal equipment such as toothbrushes, towels, razors, tableware, clothes, or by leaving pathogens in the environment after contact with patients. As a result, such infections are more common in places where things may be inadvertently shared, such as schools and the military. Examples include fungal infections such as athlete’s foot, bacterial infections such as Impetigo, warts that grow on the epidermal surface caused by a virus, and, in the peculiar case of syphilis, often the result of a healthy individual coming into contact with an infected person’s hard chancre.


Daily prevention of infectious disease tips


1.Stay away from the source of infection. If the disease around you is found to be contagious, stay away in time to avoid infection.


2.In the peak period of infectious diseases, try to stay in places where people gather as little as possible to avoid being infected.


3.The virus carrier should be treated in time to reduce the possibility of infection.


4, usually to develop good health habits, improve self disease prevention ability. In daily life, to strengthen physical exercise, more running, more playing ball, or other sports, to enhance the resistance to infectious diseases.


5, regular vaccination, so as to improve immunity, reduction and exemption of infectious diseases.


6.Do a good job in the health of the home and working environment, eliminate the pests such as mosquitoes, flies, rats and cockroaches that transmit diseases, and clean up and eliminate more corners and concealing places. To do wash hands frequently, eat cooked food, open Windows and ventilation and frequently drying clothes and other habits, and is not to drink raw water.


7.If an infectious person is found, early report and diagnosis should be made, and immediately isolated and sent to hospital for treatment to prevent cross-infection from causing greater harm. If there is contact or short life with a known infectious person, the articles and rooms that the infectious person has contacted should be strictly disinfected to fundamentally reduce the threat of infectious disease.
