Influenza in pigs is a respiratory disease similar to influenza in humans and is found worldwide. Asymptomatic infections are common. Symptoms typically appear 1–3 days after infection and include fever, lethargy, anorexia, weight loss, labored breathing, coughing, sneezing, and nasal discharge. In sows, pregnancy may be aborted.
An early morning temperature higher than 37.3 °C (99.1 °F) or a late afternoon temperature higher than 37.7 °C (99.9 °F) is normally considered a fever, assuming that the temperature is elevated due to a change in the hypothalamus's setpoint. [15] Lower thresholds are sometimes appropriate for elderly people. [15]
Eales disease is a type of obliterative vasculopathy, also known as angiopathia retinae juvenilis, periphlebitis retinae or primary perivasculitis of the retina.It was first described by the British ophthalmologist Henry Eales (1852–1913) in 1880 [1] and is a rare ocular disease characterized by inflammation and possible blockage of retinal blood vessels, abnormal growth of new blood vessels ...

Adult onset of Kawasaki disease is rare. [50] The presentation differs between adults and children: in particular, it seems that adults more often have cervical lymphadenopathy, hepatitis, and arthralgia. [32] [50] Some children, especially young infants, [51] have atypical presentations without the classic set of symptoms. [48]
The majority of the infected experienced only the typical flu symptoms of sore throat, headache, and fever, especially during the first wave. [205] However, during the second wave, the disease was much more serious, often complicated by bacterial pneumonia , which was often the cause of death. [ 205 ]
[324] [325] Children are likely to have milder symptoms and are at lower risk of severe disease than adults. [326] The CDC reports that in the US roughly a third of hospitalised children were admitted to the ICU, [ 327 ] while a European multinational study of hospitalised children from June 2020, found that about 8% of children admitted to a ...
COVID-19 symptoms range from asymptomatic to deadly, but most commonly include fever, sore throat, nocturnal cough, and fatigue. Transmission of the virus is often through airborne particles . Mutations have produced many strains (variants) with varying degrees of infectivity and virulence . [ 9 ]
