#common cold, #upper respiratory infection, #runny nose, #nasal congestion, #pharyngitis, #tonsillitis, #fever, #cough, #antibiotics, #feverish, #having a fever, #high fever, #low-grade fever, #body shaking, #feeling cold and shivering, #chills, #dry cough, #persistent cough, #cough that won't stop, #stuffy nose, #clear runny nose, #yellow runny nose, #hand tremor, #body tremor

An acute upper respiratory infection is a condition in which a viral or bacterial infection causes inflammation in the upper airway, including the nose, tonsils, pharynx (throat), and larynx (voice box). It includes what is commonly called the "common cold." The main symptoms are runny nose, nasal congestion, sore throat, cough, and fever. Adequate fluids and rest are the basic treatment, but if you have a high fever or severe symptoms, please consult an ENT specialist.

Cellulitis

#cellulitis, #soft tissue infection, #bacterial infection, #skin infection, #antibiotics, #athlete's foot, #lymphangitis, #body swelling, #facial swelling, #leg swelling, #swelling in hands and feet

Cellulitis is an infection that occurs when bacteria invade the dermis (the middle layer of the skin) and the subcutaneous fat layer. It can cause the skin to become red and swollen, along with fever and pain. If you have symptoms, you should see a medical specialist promptly.

Chronic Osteomyelitis

#chronic osteomyelitis, #osteomyelitis, #open fracture, #shinbone, #tibia, #bone infection, #flap surgery, #multidisciplinary care, #seeing double, #overlapping images

Chronic osteomyelitis is a condition in which bone is infected by bacteria and inflammation persists for a long time. It most often occurs after an open fracture (a fracture in which the bone is exposed to the outside). It is difficult to treat and often recurs, so care at a specialized medical institution is important.

Comparing the Common Cold, Influenza (Flu), and COVID-19

#common cold, #flu, #COVID-19, #influenza, #respiratory infection, #comparison, #mask, #handwashing, #sore throat, #scratchy throat, #pain when swallowing, #feeling feverish, #body heat, #high fever, #low-grade fever, #body shaking, #feeling cold and shivering, #cold sensation, #dry cough, #persistent minor cough, #cough that will not stop, #stuffy nose, #clear runny nose, #yellow runny nose, #hand tremor, #body tremor

The common cold, influenza (flu), and COVID-19 are all respiratory infectious diseases caused by viruses, but the causative viruses and symptoms differ. It is often difficult to tell the three apart from symptoms alone, so if you have any abnormal symptoms, please consult a medical specialist.

Multidrug-Resistant Organisms (Antibiotic-Resistant Bacteria)

#multidrug-resistant organisms, #antibiotic resistance, #superbug, #MRSA, #CRE, #antibiotic misuse

Multidrug-resistant organisms are bacteria that have developed resistance to several types of antibiotics. They are also called 'superbugs.' Misuse and overuse of antibiotics are the main cause, and infection with them can be very hard to treat. Please take antibiotics only as prescribed by a doctor and for the prescribed length of time. If you have questions about antibiotic use, please consult your doctor.

Noise-Induced Hearing Loss

#noise-induced hearing loss, #earphones, #tinnitus, #cochlea, #hearing damage, #noise, #hearing, #headphones, #double vision, #overlapping images, #ringing in the ear, #noise in the ear, #cannot hear, #difficulty hearing

Noise-induced hearing loss is a condition in which hearing is damaged by loud, sustained sound exposure. It once occurred mainly in industrial workplaces, but it is now increasing among teenagers and young adults as the use of personal audio devices such as earphones grows. There is currently no treatment that restores hearing once it has been damaged, so prevention is most important. If your hearing declines or you develop tinnitus, please consult an ENT specialist.

Pneumonia in Older Adults

#pneumonia, #pneumonia in older adults, #pneumococcus, #flu, #aspiration pneumonia, #vaccination, #immunity, #respiratory tract, #chest ache, #chest pain, #chest tightness, #feeling of stuffiness in the chest, #feeling feverish, #body heat, #high fever, #low-grade fever, #body shaking, #feeling cold and shivering, #cold sensation, #dry cough, #persistent minor cough, #cough that will not stop, #hand tremor, #body tremor

Pneumonia in older adults generally refers to pneumonia that occurs at age 65 or older. Pneumonia is inflammation of the lungs caused by infection with bacteria, viruses, or other organisms. More than 50% of people with pneumonia and more than 90% of people who die of pneumonia are aged 65 or older. In older adults, symptoms are often not obvious, so diagnosis is easily delayed. If you have suspected symptoms, please consult a pulmonology and allergy specialist immediately.

Proper Use of Antibiotics

#antibiotics, #antibiotic misuse, #antibiotic resistance, #correct dosing, #antibiotics for colds, #prescription, #loose stools, #watery diarrhea, #frequent bowel movements

Antibiotics are essential medications for treating bacterial infections, but improper use can lead to antibiotic-resistant bacteria, making future infections harder to treat. Please take antibiotics correctly and only as prescribed by your doctor.

Prostatitis is inflammation of the prostate, and about 10% to 12% of all men experience symptoms of it at some point. It is the most common prostate condition in men under age 50. Because treatment differs depending on the type, an accurate diagnosis is important. If you have symptoms, please consult a urologist.

A young child who has a fever without cough or runny nose may have a urinary tract infection. If treatment is delayed, the kidneys may be damaged, so be sure to consult a pediatric specialist.

Urinary tract infection is known to be more common in women, but it also occurs frequently in men, and it is increasing, especially in older men along with diabetes and benign prostatic hyperplasia (enlarged prostate). If it is not treated appropriately at an early stage, it can become chronic or lead to sepsis, so prompt diagnosis and treatment are important.
