Recently, influenza has been on the rise and several cities have issued influenza risk level warnings. In Shenzhen, the risk level of influenza was set at "medium" on June 15, 2022.
According to the national influenza surveillance data, every year in October, all parts of China have entered the influenza winter and spring epidemic season.
This year, the influenza epidemic entered the high season in summer, which is related to the different geographical locations and climatic conditions of different regions in China.
Before the New Crown outbreak, the overall epidemic intensity of influenza B in China was lower than that of type A. With the outbreak and the implementation of strict preventive and control measures, influenza was low throughout 2020, and the detection rate of influenza viruses has been increasing since early 2021, with the absolute dominance of type B (Victoria). The 22nd week of data from the National Influenza Center of China shows that the detection rate of influenza viruses in southern provinces has continued to rise recently, and some provinces have entered the summer high season, with influenza A (H3N2) viruses predominating.
Influenza generally refers to influenza. Influenza, referred to as influenza, is an acute respiratory disease caused by influenza A, B and C viruses respectively, and belongs to category C infectious diseases.
The symptoms of influenza and new crown are similar, both of them start rapidly, mainly with fever, headache, myalgia and general discomfort, body temperature can reach 39~40℃, and there can be chills and chills, mostly accompanied by general symptoms such as general muscle and joint pain, weakness and loss of appetite.
The symptoms are the same, so how can we tell if we have the flu or the new crown?
Like New Guan, influenza is also caused by the influenza virus and requires nucleic acid testing before a conclusion can be made. Since their symptoms are similar and both have fever symptoms, both may be seen in fever clinics. This is where the nucleic acid rapid test for neo-crown comes in handy.
Patients with neo-crown are stable in the early stages of the disease, and most severely ill patients develop respiratory distress or hypoxemia a week after onset, which can rapidly progress to acute respiratory distress syndrome, septic shock, uncorrectable metabolic acidosis and bleeding and coagulation dysfunction in severe cases. The mortality rate of influenza is much lower than 0.1%; while the mortality rate of neostriatal is about 3%-4%, and it spreads rapidly, so the rapid identification of neostriatal becomes a top priority in fever clinics.
Most fever clinics are equipped with a rapid nucleic acid test system that can produce rapid nucleic acid test results within one hour. The rapid test system is equipped with an efficient amplification kit portable amplification instrument, which can achieve rapid and accurate temperature rise and fall during nucleic acid amplification, shortening the time required for amplification to about 30 minutes, effectively helping to prevent and control the epidemic.
It is worth mentioning that the new crown nucleic acid rapid detection system in the high efficiency amplification reagent, which adds a high efficiency enzyme, not only for small-throughput rapid detection system, more adaptable to large-throughput conventional testing, to improve the efficiency of large-throughput testing.
