What are the common respiratory infections? Star Awareness Project

No one can not breathe, we all need it, and now the weather and air quality are so bad compared to before, many people may get sick because they live in a city with particularly poor air quality for a long time. So now you have to take protective measures when you go out, such as wearing a mask. Are upper respiratory tract infections contagious?

Are upper respiratory tract infections contagious?

1. Upper respiratory tract infection refers to the general term of acute inflammation between the nasal cavity and the larynx, which is the most common infectious disease. About 70% to 80% of upper respiratory tract infections are caused by viruses, which are contagious, especially in infants and young children with weakened immunity or the elderly, especially in patients with chronic diseases.

2. In particular, the new highly pathogenic avian influenza H1N1 and H7N9 that have appeared in recent years are more contagious. Mycoplasma infections are also contagious. If it is an ordinary bacterial infection, it is basically not infectious.

What are the symptoms of an upper respiratory tract infection.

Acute rhinitis and cold, the onset season is more likely to occur in winter and spring; Local nasopharyngeal symptoms are severe. Influenza, the disease has a rapid onset, is contagious, and the symptoms are changeable, mainly with systemic poisoning symptoms, and the respiratory symptoms are mild. Chills, high fever, general malaise, back and limb aches, fatigue, headache, dizziness, sneezing, nasal congestion, runny nose, sore throat, dry cough, and little phlegm are all symptoms of upper respiratory tract infection.

People are most afraid of getting sick, and every time they are not in good health, they have to consume energy and energy in the process of seeing a doctor and treating a disease. If the condition is severe, it will take care of ourselves for a long time, and we will often take medication, which is hurting ourselves, so we must take good care of ourselves in our daily life, reduce the number of times we get sick, and reduce the consumption of various pills, so that we will become healthier and healthier.

Most upper respiratory tract infections are contagious, and there are two main ways of transmission of this disease, the first is droplet transmission, that is, the patient can cough or talk, and the droplets in the mouth or respiratory tract can directly enter the other person's respiratory tract to cause transmission.

Another mode of transmission is contact transmission, which is more common in kindergartens, when a child's secretions are rubbed on toys or tabletops, healthy children will wipe their mouths and noses after exposure to germs, and enter the respiratory tract to cause infection.

So what causes an upper respiratory tract infection? It has a lot to do with the following reasons.

1. Viral infections, including rhinovirus infection, adenovirus infection, parainfluenza virus infection, and respiratory syncytial virus infection, are one of the main factors leading to the onset of upper respiratory tract infection.

2. Bacterial infections, the more common ones are staphylococcus, Streptococcus pneumoniae, Haemophilus influenzae, and Gram-negative bacillus infections may also lead to the onset of upper respiratory tract infections.

3. Seasonal changes, this disease is the most common in spring and winter, and it is more or less related to the reasons such as not paying attention to cold protection and warmth, or external transmission.

4. The body's resistance is low, which is more common in infants and the elderly, because after the body's resistance declines, the defense function of the respiratory tract will also be reduced, so it is more susceptible to bacterial and viral infections and inflammatory lesions.

Whether an upper respiratory tract infection is an infectious disease should be analyzed for possible infectious agents. Acute upper respiratory tract infections are usually caused by viral infections, which are somewhat contagious, but if they are caused by epidemics, it is infectious diseases.

Upper respiratory tract infection, also known as cold, is a general term that includes acute inflammation of the nasal, pharynx, or larynx. It is usually caused by viruses or bacteria. But not all upper respiratory tract infections, such as tonsil inflammation, are generally not contagious.

Upper respiratory tract infections are a normal thing, and they are also a process that people must have, just don't have too much. There are two types of upper respiratory tract infections, one is a bacterial infection and the other is a viral infection, which is contagious but not very strong.

Upper respiratory tract infection is a disease with a very high incidence, mainly through the patient's sneezing, and the airborne transmission of droplets containing the virus, that is to say, the upper respiratory tract infection can be transmitted to the surrounding people, so in daily life, the disease of upper respiratory tract infection is focused on prevention, such as in the season when the upper respiratory tract infection is prevalent, pay attention to wearing a mask when walking out to avoid the occurrence of this disease.

Upper respiratory tract infections are not infectious diseases, but it is possible to become infected if you come into contact with an infected person.

Upper respiratory tract infection is produced by viruses, bacteria and other pathogens that infect the human respiratory tract, and mostly occurs in infants and young children with poor immune function. Upper respiratory tract infections can generally heal on their own, patients should pay attention to rest, drink plenty of hot water, avoid crowded places, keep warm from the cold, and eat a light and easy to digest.

If you have symptoms such as fever, cough, nasal congestion, sore throat, etc., you can use symptomatic drugs. In addition, coupled with the appropriate application of anti-infective drugs according to the condition, it is conducive to shortening the course of the disease, and most of the prognosis is also very good, some people who are seriously ill and have poor physical constitution may have complications such as otitis media, sinusitis, bronchitis, and pneumonia.

At present, the pathogens of respiratory infectious diseases are viruses, pathogenic bacteria, mycoplasma, chlamydia, etc.

The human body is a very delicate machine, and it is very likely that the sudden change in temperature will lead to respiratory infections during the change of seasons. For respiratory diseases, acute tracheobronchitis is a typical disease, if there is a cough and phlegm, you must go to a regular hospital for treatment in time, so as to strangle the danger in the cradle. I hope that everyone can strengthen their physical exercise and improve their own immunity in life.

1. What are the pathogens that cause respiratory infections?

For viruses are divided into influenza virus, respiratory syncytial virus, adenovirus, rhinovirus, coronavirus, human enterovirus and new enterovirus, in life we must be vaccinated in time, so as to better avoid the generation of respiratory infectious diseases, for respiratory infectious diseases, high incidence in the Mid-Autumn season, we must do a good job of prevention in advance in life, so as to better protect our health.

2. How can we make our body healthier?

In life, we must learn to understand the relevant knowledge, because the pathogens of respiratory infectious diseases can be transmitted through droplets, droplets and dust, so we must wear masks in our daily life, wash our hands frequently, and do a good job of personal hygiene protection, so that we can make our body healthier, and ensure a balanced nutritious diet, reasonable sleep time and appropriate sports in life, so that our body can not be affected.

3. What is my personal opinion?

I think that the epidemic of respiratory tract infection is a more typical disease, the incidence of this disease is high, the clinical manifestations are fatigue, muscle aches and fever and cough and other symptoms, if we have respiratory tract infections in our lives, we should also go to the hospital in time for treatment Patients are the main source of infection, for susceptible people, we must do a good job of protection in time.

Colds, measles, chickenpox, rhinitis, rheumatosis, parotid glands, meningococcal meningitis, nasal cavity, throat, scarlet fever, whooping cough, etc., these are all contagious, and they can also cause serious harm and are very uncomfortable.

Influenza A virus, influenza B virus, new coronavirus, varicella virus, chlamydia pneumoniae virus, etc., there are many pathogens of respiratory tract infections, and the impact of these viruses is relatively large.

There are influenza, tuberculosis, meningococcal meningitis, mumps, chickenpox, measles, rubella, which are all diseases transmitted through the respiratory tract.

Question 1: Is upper respiratory tract infection contagious? Hello. Upper respiratory infections are contagious, mainly through respiratory droplets from the patient's respiratory tract. However, it is not a virulent infectious disease, and people with strong resistance may not necessarily get sick if they come into contact with patients.

Question 2: Are respiratory tract infections contagious? Generally speaking, respiratory tract infectious diseases are contagious, if they are not infectious, patients will not get sick, but it also depends on the specific situation, and it cannot be considered that infectious diseases must be infectious diseases, and respiratory tract infectious diseases are the most common infectious diseases.

About 90 are caused by viruses, and bacterial infections often follow viral infections. The disease can occur at any age in all seasons and is transmitted through virus-containing droplets, droplets, or contaminated utensils. Often when the body's immunity is reduced, such as cold, tiredness, rain, etc., viruses or bacteria that already exist or invade from the outside world grow and multiply rapidly, leading to infection!

Therefore, for immunocompromised patients, it is best not to contact patients with respiratory infections to avoid infection1

Question 3: Can sexual upper respiratory tract infections be contagious It is commonly known as a cold.

Question 4: Will upper respiratory tract infections be contagious Hello. Upper respiratory infections are contagious, and Chi Siu Kee is mainly transmitted through respiratory droplets from the patient's respiratory tract. However, it is not a virulent infectious disease, and people with strong resistance may not necessarily get sick if they come into contact with patients.

Question 5: Are respiratory infections contagious Respiratory infections are contagious.

1) Practice good hygiene, wash your hands after sneezing, coughing, and cleaning your nose, dry them with a clean towel or paper towel after washing your hands, and don't share towels.

2) Pay attention to a balanced diet, increase or decrease clothing according to weather changes, exercise appropriately, get enough rest, and reduce stress to enhance the body's resistance.

3) Ensure that the room is well ventilated, and open the windows frequently for ventilation. Maintain good performance of your air conditioner and clean the dust filter frequently.

4) Pay attention to the ventilation of vehicles.

5) Try to avoid going to public places with poor air circulation and dense population.

6) For influenza, measles, mumps and other vaccines that can prevent the corresponding diseases, vaccination is a better choice.

7) If you have the flu or other respiratory infections, it is best to rest at home to avoid infecting others.

Common ones include influenza, meningoccal cerebrospinal mendingitis, mumps, measles, rubella, chickenpox, 100 plates of cough, scarlet fever, diphtheria, tuberculosis, infectious atypical pneumonia, human infection with highly pathogenic avian influenza, etc.

What are the personal precautions against respiratory infections?

1) Maintain air circulation in the living and working environment, and open windows frequently.

2) Dress appropriately, increase or decrease with the climate, and pay attention to cold protection and warmth.

3) Eat a reasonable diet, eat more vegetables and fruits, ensure adequate nutrition, and drink more plain water (about 2300 ml per day).

4) Pay attention to physical exercise, improve cold tolerance and enhance physical fitness.

5) Get enough sleep and don't stay up late.

6) Pay attention to hand hygiene and disinfection, as some pathogens can be transmitted through contact with respiratory secretions.

7) During the epidemic of respiratory diseases, try to minimize going to crowded public places.

8) If you find a sore throat, you can rinse your mouth with salt water or spray your throat with a throat wind.

9) If you have a fever or symptoms of upper respiratory tract infection, you should go to the hospital in time.

10) Children should be vaccinated against measles and encephalitis on time.
