Van Nunen, a specialist in allergies, is widely recognized for her work in 2007 identifying tick-induced mammalian meat allergy, which has increased in prevalence worldwide since then. In 2007 she was the first immunologist in the world to describe in a published paper the link between ticks and meat allergy. According to van Nunen, Australia has the highest rate of mammalian meat allergy and tick anaphylaxis in the world. In 2018, after four years in development, van Nunen, in collaboration with a pharmaceuticals company and northern Sydney hospital Emergency Department, released a world-first freeze spray designed to be topically applied to ticks that have attached to humans.

Bachelor Of Medicine, Bachelor Of Surgery
Bachelor of Medicine, Bachelor of Surgery ( la, Medicinae Baccalaureus, Baccalaureus Chirurgiae; abbreviated most commonly MBBS), is the primary medical degree awarded by medical schools in countries that follow the tradition of the United Kingdom. The historical degree nomenclature states that they are two separate undergraduate degrees. In practice, however, they are usually combined as one and conferred together, and may also be awarded at graduate-level medical schools. It usually takes five to six years to complete this degree. Bachelor of Medicine (MB, also BM, BMed) is the primary medical degree awarded by medical schools in China and some medical schools in Australia and UK. It usually takes five years to complete. These medical graduates with an MB degree can still practice surgery. Both medical degrees are considered MD-equivalent in US universities and medical institutions. In North America, the equivalent medical degree is awarded as Doctor of Medicine (MD) or Doc ...

Alpha-gal Allergy
Alpha-gal allergy — or mammalian meat allergy (MMA) — is a type of meat allergy characterized by a delayed onset of symptoms (3–8 hours) after ingesting mammalian meat and resulting from past exposure to tick bites. It was first reported in 2002. Symptoms of the allergy include rash, hives, nausea or vomiting, difficulty breathing, drop in blood pressure, dizziness or faintness and severe stomach pain. Alpha-gal allergy is a reaction to the carbohydrate galactose-alpha-1,3-galactose ("alpha-gal"), whereby the body is overloaded with immunoglobulin E (IgE) antibodies on contact with the carbohydrate. Anti-gal is a human natural antibody that interacts specifically with the mammalian carbohydrate structure gal alpha 1-3Gal beta 1-4GlcNAc-R (the alpha-galactosyl epitope). The alpha-gal molecule is found in all mammals except catarrhines (apes and Old World monkeys), the taxonomic branch that includes humans. Bites from certain ticks, such as the lone star tick (''Amblyomma amer ...

Allergic Rhinitis
Allergic rhinitis, of which the seasonal type is called hay fever, is a type of inflammation in the nose that occurs when the immune system overreacts to allergens in the air. Signs and symptoms include a runny or stuffy nose, sneezing, red, itchy, and watery eyes, and swelling around the eyes. The fluid from the nose is usually clear. Symptom onset is often within minutes following allergen exposure, and can affect sleep and the ability to work or study. Some people may develop symptoms only during specific times of the year, often as a result of pollen exposure. Many people with allergic rhinitis also have asthma, allergic conjunctivitis, or atopic dermatitis. Allergic rhinitis is typically triggered by environmental allergens such as pollen, pet hair, dust, or mold. Inherited genetics and environmental exposures contribute to the development of allergies. Growing up on a farm and having multiple siblings decreases this risk. The underlying mechanism involves IgE antibodies ...

Coronavirus Disease 2019
Coronavirus disease 2019 (COVID-19) is a contagious disease caused by a virus, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The first known case was identified in Wuhan, China, in December 2019. The disease quickly spread worldwide, resulting in the COVID-19 pandemic. The symptoms of COVID‑19 are variable but often include fever, cough, headache, fatigue, breathing difficulties, loss of smell, and loss of taste. Symptoms may begin one to fourteen days after exposure to the virus. At least a third of people who are infected do not develop noticeable symptoms. Of those who develop symptoms noticeable enough to be classified as patients, most (81%) develop mild to moderate symptoms (up to mild pneumonia), while 14% develop severe symptoms (dyspnea, hypoxia, or more than 50% lung involvement on imaging), and 5% develop critical symptoms (respiratory failure, shock, or multiorgan dysfunction). Older people are at a higher risk of developing seve ...

Year Of Birth Missing (living People)
A year or annus is the orbital period of a planetary body, for example, the Earth, moving in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are generally recognized: spring, summer, autumn and winter. In tropical and subtropical regions, several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do the Julian calendars. For the Gregorian calendar, the average length of the calendar year (the ...
