Respiratory Syncytial Virus Infection (RSV) : Respiratory syncytial virus, or RSV, is a respiratory virus that infects the lungs and breathing passages. Most otherwise healthy people recover from RSV infection in 1 to 2 weeks. However, infection can be severe in some people, such as certain infants, young children, and older adults.
Treatment is limited to supportive care which includes fluids and oxygen until the illness runs its course. Salbutamol may be used in an attempt to relieve any bronchospasm if present. Increased airflow, humidified and delivered via nasal cannula, may be supplied in order to reduce the effort required for respiration. Adrenaline, bronchodilators, steroids, antibiotics, and ribavirin are also used.
Urinary tract infection : A urinary tract infection, or UTI, is an infection of the urinary tract. The infection can occur at different points in the urinary tract including:
• Bladder -- an infection in the bladder is also called cystitis or a bladder infection.
• Kidneys -- an infection of one or both kidneys is called pyelonephritis or a kidney infection.
• Ureters -- the tubes that take urine from each kidney to the bladder are only rarely the site of infection.
• Urethra -- an infection of the tube that empties urine from the bladder to the outside is called urethritis.
Causes
Most urinary tract infections are caused by bacteria that enter the urethra and then the bladder. The infection most commonly develops in the bladder, but can spread to the kidneys. Women tend to get them more often because their urethra is shorter and closer to the anus than in men. Because of this, women are more likely to get an infection after sexual activity or when using a diaphragm for birth control. Menopause also increases the risk of a UTI.
The following also increase your chances of developing a UTI:
• Diabetes
• Advanced age and conditions that affect personal care habits (such as Alzheimer's disease and delirium)
• Problems emptying the bladder completely
• Having a urinary catheter
• Bowel incontinence
• Enlarged prostate, narrowed urethra, or anything that blocks the flow of urine
• Kidney stones
• Staying still (immobile) for a long period of time (for example, while you are recovering from a hip fracture)
• Pregnancy
• Surgery or other procedure involving the urinary tract
Symptoms
The symptoms of a bladder infection include:
• Cloudy or bloody urine, which may have a foul or strong odor
• Low fever in some people
• Pain or burning with urination
• Pressure or cramping in the lower abdomen or back
• Strong need to urinate often, even right after the bladder has been emptied
If the infection spreads to your kidneys, symptoms may include:
• Chills and shaking or night sweats
• Fatigue and a general ill feeling
• Fever above 101 degrees Fahrenheit
• Pain in the side, back, or groin
• Flushed, warm, or reddened skin
• Mental changes or confusion (in the elderly, these symptoms often are the only signs of a UTI)
• Nausea and vomiting
• Very bad abdominal pain (sometimes)
Treatment
• A simple UTI can be treated with a short course of oral antibiotics. You should also remember to drink plenty of liquids, especially around the time of a UTI.
• If the UTI is a complicated UTI, then a longer period of antibiotics is given and usually is started intravenously in the hospital. After a short period of intravenous antibiotics, then the antibiotics are given by mouth for a period up to several weeks. Kidney infections have usually been treated as a complicated UTI.
Chlamydia : Chlamydia is an infection caused by the bacteria Chlamydia trachomatis. It is most commonly sexually transmitted. Chlamydia infection is the most common sexually transmitted infection in the United States. Sexually active individuals and individuals with multiple partners are at highest risk.
Symptoms
As many as 25% of men with chlamydia have no symptoms. In men, chlamydia may produce symptoms similar to gonorrhea. Symptoms may include:
• Burning sensation during urination
• Discharge from the penis or rectum
• Testicular tenderness or pain
• Rectal discharge or pain
About 70% of women with chlamydia have no symptoms. Symptoms that may occur in women include:
• Burning sensation during urination
• Painful sexual intercourse
• Rectal pain or discharge
• Symptoms of PID, salpingitis, liver inflammation similar to hepatitis
• Vaginal discharge
Treatment
The usual treatment for chlamydia is antibiotics, including tetracyclines, azithromycin, or erythromycin.
