Abstract

The novel coronavirus-infected pneumonia (NCIP) was first recognized in December 2019 in Wuhan, China and then spread successively around the world. The epidemic has spread rapidly and aroused widespread concern and panic in China with more than 80 thousand recorded infections and over 3 thousand deaths by March 2020. We have examined the effects of atmospheric conditions on the incidence of NCIP in Wuhan, Hubei province. Our results indicate a significant correlation between the new confirmed NCIP case and maximum wind velocity (r2=0.713). Both mean temperature (r2=-0.691) and air pressure (r2=-0.503) have negative associations with daily new cases. The regression equation y = 4590.899 − 1.239𝑥𝑡 − 0.442𝑥𝑝 + 0.579𝑥𝑤 was derived to define the optimal climatic conditions for the NCIP epidemic. To verify these results, further investigations in other regions are necessary.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Separation Anxiety

Separation anxiety is a type of anxiety disorder that involves excessive distress and anxiety with separation. This may include separation from places or people to which they have a strong emotional connection with. It often affects children more than adults.
