Nowadays, many people may face many diseases and infections in their daily lives, especially some viral ones, which trouble many people.

Because everyone knows that general viral infections are contagious.

Let's take a look at whether virus infection is contagious, what to do if you get infected with the virus, and how to prevent virus infection.

Can virus infection be contagious? Currently, the virus is at a high incidence. Once this disease appears in everyone's daily life, we must treat it with caution.

So will the virus infection be contagious? Viral infection is contagious, and both adults and children can be infected with the virus, and it has the nature of transmission.

Infectious diarrhea can occur throughout the year, with infections mainly affecting adults and school-age children, with high incidence during the cold seasons.

Intestinal transmission is the main cause of collective outbreaks through contaminated water, food, articles and air.

The type of virus infection, the type of virus infection is also different, so after infection, everyone must be clear about the type of virus you are infected with.

Only in this way can the treatment be more effective.

So what are the types of virus infections? 1. Occult infection.

Most viral infections are latent infections.

2. Overt infection.

A few viral infections are overt infections.

Overt infections can be divided into two types: acute infections and persistent infections.

(1) Acute infections develop rapidly and develop rapidly.

The course of the disease usually lasts from days to weeks. Except for those who die in the acute phase and sequelae, most cases eventually recover in viral tissues and organs.

(2) Continuously infected viruses persist in the host for months to years, causing chronic persistent infection, which can be divided into three types.

Latent infection When the virus and human immunity are in a relatively balanced state, the virus can lurk in human tissues for a long time without causing symptoms.

Once the immune system is weakened, viruses can replicate and cause symptoms such as herpes simplex virus, Epstein-Barr virus and varicella, and reactivated latent infections due to herpes zoster virus.

Chronic infection of viruses persists in the body tissues and organs, leading to chronic persistent diseases such as chronic hepatitis B virus-induced chronic hepatitis B.

Virus infections, with a long incubation period of several years, progressively develop and eventually lead to death.

Viral infection modes are diverse, and in daily life, if one is slightly careless, they may easily be infected with viruses.

What are the routes of virus infection? 1. Viral aerosols containing viruses in respiratory air are inhaled into the respiratory tract via the mouth and nose, with influenza virus, adenovirus, and measles virus being transmitted through this route.

2. Fecal matter containing viruses in the digestive tract is transmitted through contaminated water, food, utensils, hands and flies into the digestive tract.

By this means, the hepatitis A virus and rotavirus can be transmitted.

3. Viruses can enter the human body through skin wounds, injection sites, bite wounds from arthropods, and injuries to the skin and animal wounds.

Viruses such as rabies virus, hepatitis B virus, HIV and insects-carrying viruses can be transmitted through this pathway.

4. The virus-containing secretions of the eyes, oral cavity and reproductive tract can be directly infective by contact with these areas, including herpes simplex virus, adenovirus and HIV.

5. Placental viruses infect the fetus through the mother through the placenta, such as rubella virus, cytomegalovirus and hepatitis B virus.

What to do if you are infected by the virus? Many people feel very troubled after being infected with the virus, because the harm of this disease is still very high.

For families, adequate defense and preparation must be made.

So, what if I get infected with the virus? 1. Fasting is temporary because you cannot accept any food when you vomit, and you may even spit out warm water.

2. Drinking a small amount of warm salt water or ginger brown sugar water can gradually achieve the effect of stopping emetics and cooling.

If you have home remedy salt, you can take it directly, if you don't have it, you can make it yourself, put your home salt in boiling water and let it heat after it dissolves.

The taste in your mouth is equivalent to the salty taste of your skin.

3. If you only see fever and vomiting, if you have not solved the problem of defecation for several days, you should first defecate.

You can go to the local pharmacy and purchase kerosene, or you can use a soap in your home to trim your fingernails. This will allow you to achieve relief from constipation and fever.

4. You can eat some boiled ginger and salt porridge, not too thick, the thinner the better.

How to prevent viral infection. Viruses can infect humans through various ways, and once they occur, timely treatment is required.

However, if we can prevent it in our daily lives, it will be quite useful. So, how to prevent virus infection? Although viruses can infect humans through various routes, the main route is through food, i.e., from the mouth to diseases.

For instance, eating contaminated food, touching contaminated utensils, consuming items without cleaning them first, etc.

Therefore, the most important preventive measures are handwashing before and after meals, and remember to use soap.

It is important to remind you that you must wash your hands frequently during cooking.

For instance, when taking a call, blowing one's nose, or dealing with raw fish, some people use alcohol-based hand sanitizer at home. But that just adds to the "splendid finishing touches."

Some people are afraid that the cooking time of seafood will make it old, which will give the virus a chance.

Filter-feeding bivalves can concentrate viruses in their guts, so seafood lovers should be careful when enjoying oysters.

Remember, cooking is the common principle to prevent food-borne illnesses, and viruses are not completely killed by heat.
