Guangzhou influenza monitoring data tips

Guangzhou has entered the influenza summer peak!

For the recent increase in cases of fever cases

The Guangzhou Municipal Committee of Health and Health issued relevant notices

Children aged 0-14 can go home and wait for nucleic acid results to go home for a hot clinic.

Is the flu a cold?

The difference between ordinary colds and influenza

The difference between the two concepts:

Ordinary cold, also known as an upper respiratory tract infection or feeling. It is a general term that includes acute inflammation of the nasal, pharynx, or throat. You remember that this refers to a set of diseases, including viral pharyngitis, laryngitis, herpes pharyngitis, pharynxual hyperopthamia, bacterial pharyngeal-tonsillitis, and so on.

Influenza: The full name influenza is an acute respiratory tract infection caused by the flu virus. Note that it is specially refers to upper respiratory infections caused by the flu virus.

Different pathogenic differences:

The pathogen that causes ordinary colds can be viruses or bacteria. The most common viruses are rhinovirus, adenovirus, and intestinal virus, respiratory syndicocytosis. Bacteria are mainly hemolytic splin bacteria, including Bacillus and pneumonia, pneumonia Bacteria, bacteria, etc.

The specialized flu virus that causes influenza, including A, B, and C, influenza. Although the flu virus is often mutated, and there are many subtypes below each type, the most related to the people of our people is A (H1N1) [New A 1], A (H3N2) [Type A 3], B (Victoria) [BV Series], B (YAMAGATA) [BY) [By), which is the highest proportion of infection in the crowd, we are commonly known as seasonal influenza.

In recent years, different influenza viruses have become popular

So, what flu is currently popular in Guangzhou?

At present, type A flu, and the popular strains are "type A 3", that is, A (H3N2) subtype influenza virus.

After discomfort, which methods can help judge yourself

Is it a cold or a flu?

It is particularly important to combine the following points

Symptom difference:

The clinical symptoms of ordinary colds are often concentrated as the upper respiratory discomfort. It mainly includes obvious nasal congestion, itchy throat, cough and runny nose, and occasionally there is too much heat and headache.

The clinical manifestations of influenza are mainly high fever (≥39 ° C for 3-4 days), obvious systemic muscle soreness and fatigue, and the symptoms of upper respiratory tract symptoms such as sore throat and cough are relatively mild.

Clinical laboratory testing:

Routine clinical blood tests are not specific testing items that distinguish between common colds and flu, but they are often used to assist in determining whether there are pathogenic infections such as bacterial, virality, and mycoplasma.

The most basic simple judgment method is: sharp increase in white blood cells, significantly higher neutral granulocytes, C -reactive protein high may be bacterial infections (or mixed infections), while white blood cells are not high, lymphocyte counting, C reactive protein Not high, it is likely to be a virus infection. Of course, it is necessary to judge the clinical symptoms above.

With the improvement and popularization of detection methods

Many medical institutions are gradually carried out

Fluid antigen fast detection and

Influenza virus nucleic acid detection project

Can help us judge whether the influenza virus is infected

Differences in epidemiology:

The above two characteristics are concentrated at the individual level. Experts from public health discover the difference between ordinary colds and influenza popularity from the group level, which can be identified in combination with symptoms and test results.

Different contagious:

Although they are all diseases of the respiratory tract, the infectiousness of ordinary colds is limited, and there are few gatherings of families, communities, and collective units. Therefore, there are fewer old children and elderly people.

However, the influenza virus, due to the height variation and the difficulty of the crowd to produce continuous and stable immune barrier, have a strong contagiousness, and it is easy to gather crowds.

Different seasonal seasons:

Due to the different growth and growth characteristics of the pathogen, influenza often appears in winter and spring seasons, and in Guangzhou, March-July is a high incidence season.

The common cold, because there are many types of pathogens, and each popular season is crossing each other. Therefore, the seasonal seasonality is not obvious.

How does influenza spread? Who is more likely to be infected?

Who can spread flu?

Influenza patients and hidden infections are the main sources of infection.

How does influenza spread?

The flu is mainly influenza and other droplets such as sneezing and cough. The influenza virus survives in the air for about half an hour. It can be infected directly or indirectly through the oral cavity, nasal cavity, eyes and other mucosa. Essence

In places with dense and enclosed and ventilated crowds, influenza may also be transmitted in the form of gas solution.

Who is more likely to be infected with flu?

The crowd is generally susceptible to influenza. People with high risk of influenza complications include children, elderly, pregnant women, medical staff, people with chronic basic diseases such as asthma, diabetes, and heart disease.

TIPS: If the infection flu is diagnosed, the right medicine needs to be prescribed! If you buy medicine yourself, pay attention to the use of antibiotics or general antiviral drugs in influenza patients and do not achieve the treatment effect, and it will delay the course of disease.

How to prevent flu?

Maintaining good personal hygiene habits is an important means to prevent influenza infectious diseases such as influenza, including:

Washing your hands frequently;

In the influenza popular season, try to avoid going to the crowd's gathering place;

After the symptoms of influenza occur, cough, sneeze paper towels, towels, etc. cover your mouth and nose and wash your hands to avoid contact with your eyes, nose or mouth;

When family members have influenza patients, try to avoid mutual contact, especially when there are elderly and chronic disease patients in the family; when parents have influenza symptoms to go to the hospital, they should be protected by children and themselves at the same time (such as wearing wearingMask), avoid cross -infection;

When there is a case of influenza samples such as schools such as schools and childcare institutions, patients should rest at home to reduce disease transmission.

The flu vaccine per year is

Prevent the most economical and effective means of influenza

It can significantly reduce the influenza and influenza and

The risk of severe complications
