I. Introduction Ale-, Ble- and Novo-Victoral Infections are common infectious diseases and prone to outbreaks in densely populated places such as schools, child-care institutions, etc. Understanding the differences between their symptoms and their means of transmission helps to identify, isolate and treat in a timely manner and to prevent and control the spread of diseases.
II. Symptoms Difference
(i) Influenza A is caused by influenza A virus and is acute. Heat is a prominent symptom, with a temperature of 39 – 40°C and a temperature of 3 – 5 days. For example, when some children become infected, the temperature rises rapidly and continues to remain high. All-body symptoms are evident, including headaches, muscular acidity, especially in the limbs, back and so forth, severe sourness, often extremely weak, and a significant decrease in activity endurance. Respiratory symptoms are coughing, ache, fluorine, nose plugs, and coughing is mostly dry, which seriously affects sleep and daily life. Some patients, especially children, may also experience gastrointestinal symptoms such as vomiting and diarrhoea.
(ii) Symptoms of b. Influenza B is caused by a type B influenza virus with similar symptoms to those of the aluminum, but may be of a lesser overall extent. There is also a high heat, with more body temperature at about 39°C and a fever lasting about 3 – 4 days. All-body symptoms such as headaches, muscular acidity and inactivity are also more common. Respiratory symptoms are also dominated by cough, ingesting and aldicarb. Compared to the acetal current, the ethyl current is less likely to cause gastrointestinal symptoms, although when it occurs, it is similar to the gastrointestinal symptoms caused by the acetal current.
(iii) Nonovirus symptoms. The most frequent symptoms are nausea, vomiting, diarrhoea, high levels of vomiting, mostly of stomach content, and children tend to experience vomiting more acutely than adults. Diarrhoeal diseases, which are generally water-coated or defecated, are free of sepsis and can reach several or more times a day. Some of the patients are accompanied by hypothermia, cold fighting, headaches, muscle pains, as well as whole-body symptoms of reduced appetite and lack of strength. Symptoms usually last between 1 and 3 days and are self-reducing.
III. Differing means of communication
1. Sneeze transmission: a patient coughs, sneezes, a virus-containing foam is sprayed when speaking, and can be infected if inhaled. In the classroom, after the patient coughs, close-range students are vulnerable to infection by inhaling foam. 2. Exposure to transmission: hand contact with virally contaminated articles such as doorknobs, elevator buttons, etc., re-exposure of mouth, nose, eye mucous membrane, which can enter the human body.
(ii) The means of transmission of the B-stream are similar to those of the A-stream. It is transmitted mainly by foam, which is carried by the patient ‘ s respiratory tract and spread to others at short distances in the air. Exposure is also an important way of spreading, and contaminated surface viruses can spread to easy-to-discovery people.
(iii) Notrovirus transmission pathways
1. Manure – oral transmission: is the main mode of transmission. Patients’ faeces and vomits contain a large number of viruses, and if they contaminate water sources, food, others are exposed to, or vulnerable to, infection. In the course of food production, cooks are infected with the virus and are able to contaminate food products, causing many people to eat and develop disease. Indirect exposure transmission: Exposure to environmental surfaces, articles, such as tables and chairs, toys, etc., contaminated by vomiting or faeces of patients, and re-exposure to mouth can also be infected. In places such as school classrooms, canteens, etc., the spread of the virus can be easily caused by the lack of timely clean sterilization. 3. Aerosol transmission: When patients vomit, virus-containing aerosols can be produced and others may be infected by inhalation of aerosols in relatively confined spaces.
Summary
There are differences in the symptoms and transmission pathways of the A, B and Nova viruses. Ale- and E-streams are mainly characterized by respiratory and overall body symptoms, which rely on fluorine and exposure; and Novovirus-focal gastrointestinal symptoms, which are transmitted through faecal – mouth, indirect exposure and aerosols. In daily life, measures such as hand washing, masking, maintaining social distance, and attention to food and water hygiene are essential for the prevention of these infectious diseases. In case of symptoms, medical treatment should be provided in a timely manner.
