There are two types: anterior (the most common), and posterior (less common, more likely to require medical attention). Sometimes in more severe cases, the blood can come up the nasolacrimal duct and out from the eye. Fresh blood and clotted blood can also flow down into the stomach and cause nausea and vomiting. It is rarely fatal less

These dysfunctions can present in a variety of ways, such as the stimuli not activating the olfactory bulb, some odors being interpreted as other odors, or hallucinations of smells. These subsets are called anosmia, parosmia, and phantosmia respectively. Anosmia and hyposmia (a less severe form of anosmia with a decreased sensitivity to smell but not the complete lack of it) are more quantitative disabilities typified by degrees in which the odor is sensed. Parosmia and phantosmia are more qualitative disabilities that are denoted by the impromptu introduction of odors without the proper stimulus less

The condition is usually fatal and generally only affects immunocompromised people such as patients with leukemia, lymphoma or those that have had organ transplants or chemotherapy. The infectious agent is saprophytic fungi. less

Most cases are due to a viral infection and resolve over the course of 10 days. Sinusitis can be acute (going on less than four weeks), subacute (4–8 weeks) or chronic (going on for 8 weeks or more).All three types of sinusitis have similar symptoms, and are thus often difficult to distinguish. Acute sinusitis is very common. less

Common symptoms include a cough, sore throat, runny nose, and fever. There is currently no known treatment that shortens the duration; however, symptoms usually resolve spontaneously in 7 to 10 days, with some symptoms possibly lasting for up to three weeks.The common cold is the most frequent infectious disease in humans with the average adult contracting two to four infections a year and the average child contracting between 6–12.Collectively, colds, influenza, and other upper respiratory tract infections (URTI) with similar symptoms are included in the diagnosis of influenza-like illness. less
