How to distinguish between bacterial cold and viral cold
Bacterial colds and viral colds can be distinguished by a complete blood count. A viral cold, generally caused by a viral infection, is characterized by symptoms such as nasal congestion, runny nose, sneezing, sore throat, and mild fever. Bacterial colds, on the other hand, often present with chills and high fever, sore throat, and pus in the tonsils. In viral colds, lymphocyte counts are elevated, and there is no significant increase, or no increase, in the total white blood cell count. Bacterial colds show an increase in white blood cells and neutrophils.
Can you drink alcohol if you have a cold?
It is not recommended to drink alcohol during a cold. This is because alcohol can suppress the central nervous system and affect the absorption of medications, especially cephalosporin drugs. One must not drink alcohol as it can pose a life-threatening risk. Whether it is beer, Western liquor, or strong spirits, none should be consumed. Since a cold itself can cause symptoms of fatigue and weakness, adding alcohol can potentially worsen these symptoms. Additionally, consuming alcohol while on cold medications is not advised, as it can lead to poor mental focus, and alcohol can exacerbate the symptoms of a cold.
How long will the symptoms of a cold last?
The duration of cold symptoms varies depending on individual constitution and the type of cold. Generally, a common cold may take three to five days to recover, while influenza could require five to ten days. The specific duration depends on the quantity of the virus and the body's immune capacity. Both influenza and the common cold are viral infections that cause illness, and there are some differences in symptoms. However, the treatment plans are the same, focusing on symptomatic treatment, complemented by antiviral medication, with recommendations to drink plenty of water, rest, and boost metabolism.
What is a cold?
Colds are classified as a type of disease, and clinically, they are mainly divided into common colds and influenza. They are among the most common respiratory infectious diseases in daily life, caused by viral infections. The common cold is mainly caused by rhinoviruses, adenoviruses, and other viruses, while influenza is mostly caused by influenza viruses or parainfluenza viruses and other pathogens. Symptoms include drowsiness, fatigue, fever, nasal congestion, runny nose, and sneezing. The main treatments include drinking plenty of water, antiviral therapy, and symptomatic treatment.
Which department should I visit for a cold?
A cold is a common self-limiting disease in daily life, and it is also somewhat contagious. For treatment and examination, one can visit the general internal medicine department or the respiratory department at a hospital. If it is a severe contagious cold, such as an epidemic influenza, it is advisable to go to the infectious disease department of the hospital for examination. The main principle is symptomatic treatment and antiviral management, while avoiding stress. Mild cases may recover on their own within three to seven days without medication or treatment, simply by resting and drinking plenty of water. However, if the symptoms are severe, timely examination should be sought to prevent complications.
Can I eat oranges when I have a cold and cough?
People with a cold and cough can eat oranges. This fruit is rich in vitamin C, which can promote the repair of tissue mucosa and is beneficial for recovery from illnesses. Additionally, it can also provide some cough relief. Therefore, it's fine to eat oranges when you have a cold and cough, as generally, there are no special contraindications with most fruits. Fruits like apples, bananas, tomatoes, tangerines, pineapples, and dragon fruits are also edible. It is mainly important to avoid overly greasy and spicy foods, refrain from smoking and drinking alcohol, drink plenty of water, ensure good indoor air circulation, and maintain suitable indoor temperature and humidity to help recover from a cold and cough.
What is good to eat when you have a cold?
For dietary considerations during a cold, it is generally advisable to eat light, consume more fruits and vegetables, and avoid spicy, greasy, raw, or cold natured foods. If the cold is severe, some cold medicines may be necessary to combat the virus. It's important to rest regularly and avoid excessive fatigue. Consuming foods like millet porridge, Eight-Treasure porridge, egg soup, and thin noodles can be beneficial as these foods are nutritious and do not burden the gastrointestinal tract, aiding in the recovery from a cold. When the body's immune function is compromised, viral infections may occur, necessitating antiviral medications for treatment.
Characteristics of whooping cough
Whooping cough is a respiratory infectious disease characterized by paroxysmal coughing and spasmodic cough. Some patients may exhibit a crowing sound similar to a rooster's crow or a bark-like cough. Adult patients may experience symptoms such as facial redness, runny nose, and vomiting. Diagnostic confirmation requires appropriate auxiliary tests. Once diagnosed, it is recommended to undergo isolation treatment and choose a sufficient amount of effective antibiotics to eradicate the Bordetella pertussis bacteria.
How to diagnose the incubation period of pertussis
The incubation period of whooping cough generally has no autonomous discomfort symptoms. If there is close contact with a patient and the body lacks antibodies, suspecting the presence of this pathogen, corresponding auxiliary examinations can be conducted for diagnosis. Bacteriological examinations and fluorescent antibody methods can be performed, using nasopharyngeal swab secretions smear or nasal mucosa impression smear fluorescent antibody staining to detect specific antigens, with an early positive rate of 75%-85%. Complement fixation tests in serology can also be conducted to detect specific antibodies, effectively aiding in the diagnosis of atypical cases.
Does whooping cough require isolation?
Pertussis, this contagious disease, once diagnosed, requires isolation to prevent infection to healthy children or even adults with low immunity. It is necessary to provide an isolated room for the child, and attention should be paid to indoor ventilation, appropriate temperature, frequent cleaning and sunning of clothes and bedding, ensuring adequate and good sleep, and maintaining clean, ventilated air indoors. Dietary adjustments should also be made, avoiding too cold, spicy, or acidic foods. Timely selection of sensitive antibacterial drugs and cough suppressants can help alleviate symptoms of coughing and wheezing.
