The cold winter will hit, the flu is active, the new crown + flu mandarin duck doubles, netizens can't stand it!
Editing | Alaska Po
It's been ridiculously hot across the country this summer! Extremely outrageous! As the old saying goes, after a big summer, there must be a big cold, and this winter is a bit unusual
.
In the past two days, according to the latest monitoring results of the National Climate Center, the equatorial Middle East Pacific La Nina event is further continuing and is expected to extend to the winter
of 2022 to 2023.
La Niña refers to the phenomenon of unusually cold SST in the equatorial Middle East Pacific, which affects the global climate
through atmospheric circulation.
In the winter after the La Niña event, most areas of China usually have lower temperatures than usual, with less precipitation on a large scale, and are prone to low-temperature freezing damage and snow disasters
.
In this way, this year's winter is a little difficult, after all, it is only October, and a round of cold air is already rushing
towards us.
In the harsh winter, the first thing that has to be mentioned is "influenza", referred to as influenza!
According to the latest data from the World Health Organization, since the beginning of this year, the global incidence of influenza has increased significantly, the number of reported cases has increased significantly compared with the past two years, and the risk of global seasonal influenza transmission has increased
.
Since June this year, influenza activity in China's southern provinces has once again shown a rapid increase, entering a summer high incidence period, reaching the highest level
in the same period in nearly five years.
Since August, the positive rate of influenza virus testing in some northern provinces has increased, higher than the same period in the past five years, indicating that the influenza situation this winter and next spring is not optimistic
.
The summer flu, which has appeared in the northeast for the first time in three years, is extremely abnormal and really
long-lived.
After surveillance, this time it was a wave of A (H3N2) influenza virus, experts said that in Dalian, influenza is generally epidemic in winter and spring, and this is the first time in three years that influenza virus is monitored in summer
.
In view of the outbreak of influenza in summer, Dong Xiaoping, chief expert of virology of the Chinese Center for Disease Control and Prevention, previously made some reminders at the press conference of the joint prevention and control mechanism of the State Council on the future trend of influenza this autumn and winter: "This summer, the epidemic peak of the A (H3N2) subtype influenza virus has appeared in the south of our country, and experts judge that the risk of a higher level of influenza epidemic this autumn and winter is high
.
”
Cold winter + flu high level epidemic risk, really a good pair of sadistic partners
.
One problem, if the new crown and influenza co-epidemic, there is a superimposed situation, a large number of cases with similar respiratory infection symptoms will increase the complexity of the differential diagnosis of new crown pneumonia cases by medical institutions, resulting in some new crown pneumonia cases may be difficult to detect and manage in time, which may aggravate the risk of new crown virus transmission; Severe hospitalizations associated with respiratory infections will also lead to an increased demand
for hospital beds, ventilators, and ICUs.
How can this be done?
The Lancet: 88,000 people die from the flu in China every year! Under the high risk of influenza outbreak, we must not let down our vigilanceWe're all on the lookout for coronavirus, but beware of a possible flu outbreak this winter!
As early as two years ago, Yu Hongjie's team at the School of Public Health of Fudan University, together with the Chinese Center for Disease Control and Prevention and the University of Hong Kong, published a research entitled "Influenza-associated excess respiratory mortality in China, 2010-15: a population-based" in the Lancet Journal of Public Health research papers
.
The study shows that in the five years from 2010 to 2015, there were an average of 88,100 influenza-related excess respiratory deaths nationwide each year, accounting for 8.
2% of all respiratory deaths, and the elderly over 60 accounted for 80%
of influenza-related excess respiratory deaths.
This is the regular number
of flu deaths each year before the pandemic.
After the outbreak of the new crown, this data decreased, because the new crown epidemic has greatly deepened people's protection against the virus, wearing masks in public places has become a habit for many people, which is conducive to influenza prevention and control, influenza has been at a low level of epidemic, so the number of influenza infections and deaths has decreased
in the past two years.
However, the long-term low level of epidemic does not necessarily bring all positive effects, at this time it may be necessary to ask, is it bad that the flu is "less"?
According to experts, if it is in a state of low-level epidemic for a long time, the proportion of naturally infected people will be very low, and the pre-existing immunity to influenza viruses in the population will decrease
.
Pre-existing immunity provides some protection to the population and limits influenza epidemics, and when pre-existing immunity is reduced, the population may be more prone to large outbreaks or influenza pandemics
when the next influenza virus hits.
Especially in the case of a small outbreak of influenza this summer + a high epidemic risk this autumn and winter, this winter is really not good, we must not take it lightly!
Vaccines and special drugs are the two major weapons against influenza! But flu screening is a challengeFor the flu, you must never equate it with the common cold anymore! Can the two be the same?
That is to say, influenza is an acute respiratory infection caused by influenza virus, and it is also a highly contagious and fast-spreading disease, which can be divided into three types
: A (A), B (B), C (C).
The severity and risk of influenza are greater than that of the common cold, generally manifested as acute onset, fever (some cases can appear high fever, up to 39 ° C-40 ° C), accompanied by chills, headache, muscle and joint pain, extreme fatigue, loss of appetite and other systemic symptoms, common sore throat, cough, nasal congestion, runny nose, retrosternal discomfort, facial flushing, mild conjunctival hyperemia, vomiting, diarrhea and other symptoms
.
Mild influenza often resembles the common cold, but fever and constitutional symptoms are more pronounced; Severe cases can have a variety of complications such as viral pneumonia, secondary bacterial pneumonia, acute respiratory distress syndrome, etc.
, and influenza complications are more common in the elderly over 60 years old, which accounts for more than half of the 88,000 deaths every year!
This winter, once the influenza breaks out, it is easy to cause fever outpatient patients to be full, but in the face of sudden demand for testing, hospitals are prone to problems such as unbearable testing throughput and lagging test result reporting.
Nowadays, influenza testing is relatively expensive, so it is a problem
that has to be considered in advance if you want to screen for influenza cases more, quickly and accurately.
In response, the Chinese Center for Disease Control and Prevention has issued an urgent notice to remind the public to actively prevent influenza
.
But, fortunately, facing the flu is not as helpless as facing the new crown, and we still have special drugs and vaccines
.
Recently, the Heilongjiang Provincial Center for Disease Control and Prevention and other provinces have reminded the public to pay attention to timely vaccination against influenza to prevent possible influenza outbreaks
.
The new influenza vaccine guidelines update the national influenza prevention and control policies and measures, the latest approved influenza vaccine types, and the influenza vaccination recommendations
for 2022-2023.
Previously, there have been many cases of flu vaccine out-of-stock
.
For influenza specific drugs, the two more mature drugs are oseltamivir and mabaloxavir
.
The former has been clinically applied for many years and its effect has been tested for a long time; The latter was approved for marketing in China in April 2021, and it can stop the virus from replicating within 24 hours with only one tablet throughout the process, and is known as the "flu miracle drug"
.
With these two drugs, I believe we can be more relaxed
in the face of influenza.
The menacing flu has hit us, are we ready?
