In sickle-cell anemia, osteomyelitis due to Salmonella infection is much more common than in the general population. Though Salmonella infection is frequently the cause of osteomyelitis in people with sickle-cell, it is not the most common cause, which is Staphylococcus infection.Those infected may become asymptomatic carriers, but this is relatively uncommon, with shedding observed in only 0.2 to 0.6% of cases after a year. Causes
Contaminated food, often having no unusual look or smell
Poor kitchen hygiene, especially problematic in institutional kitchens and restaurants because this can lead to a significant outbreak
Excretions from either sick or infected but apparently clinically healthy people and animals (especially dangerous are caregivers and animals)
Polluted surface water and standing water (such as in shower hoses or unused water dispensers)
Unhygienically thawed poultry (the meltwater contains many bacteria)
An association with reptiles (pet tortoises, snakes, iguanas, and aquatic turtles) is well described. Amphibians such as frogsSalmonella bacteria can survive for some time without a host; they are frequently found in polluted water, with contamination from the excrement of carrier animals being particularly important.The European Food Safety Authority  highly recommends that when handling raw turkey meat, consumers and people involved in the food supply chain should pay attention to personal and food hygiene.An estimated 142,000 Americans are infected each year with Salmonella Enteritidis from chicken eggs, and about 30 die.
They can include

Dry or sore throat
Coughing (both a causal factor and a symptom of laryngitis)
Frequent throat clearing
Increased saliva production
Dysphagia (difficulty swallowing)
Sensation of swelling in the area of the larynx (discomfort in the front of the neck)
Globus pharyngeus (feeling like there is a lump in the throat)
Cold or flu-like symptoms (which, like a cough, may also be a causal factor for laryngitis)
Swollen lymph nodes in the throat, chest, or face
Fever
General muscle pain (myalgia)
Shortness of breath, predominantly in children

Voice quality
Aside from a hoarse-sounding voice, changes to pitch and volume may occur with laryngitis. Speakers may experience a lower or higher pitch than normal, depending on whether their vocal folds are swollen or stiff. They may also have breathier voices, as more air flows through the space between the vocal folds (the glottis), quieter volume and a reduced range. Causes
Laryngitis can be infectious as well as noninfectious in origin. The resulting inflammation of the vocal folds results in a distortion of the sound produced there. It normally develops in response to either an infection, trauma to the vocal folds, or allergies. Chronic laryngitis may also be caused by more severe problems, such as nerve damage, sores, polyps, or hard and thick lumps (nodules) on the vocal cords. [4]

Acute
Viral
Most acute cases of laryngitis are caused by viral infections, the most common of which tend to be rhinovirus, influenza virus, parainfluenza virus, adenovirus, coronavirus, and RSV. In patients who have a compromised immune system, other viruses such as herpes, HIV may also be potential causes.
