Risk for Transportation of 2019 Novel Coronavirus Disease from Wuhan to Other Cities in China.
On January 23, 2020, China quarantined Wuhan to contain coronavirus disease (COVID-19). We estimated the probability of transportation of COVID-19 from Wuhan to 369 other cities in China before the quarantine. Expected COVID-19 risk is >50% in 130 (95% CI 89-190) cities and >99% in the 4 largest metropolitan areas.

The beginning of 2020 has seen the emergence of COVID-19, an outbreak caused by a novel coronavirus, SARS-CoV-2, an important pathogen for humans. There is an urgent need to better understand this new virus and to develop ways to control its spread. In Iran, the first case of the COVID-19 was reported after spread from China and other countries. ⋯ Laboratory evidence of clinical patients showed that a specific T-cell response against SARS-CoV-2 is important for the recognition and killing of infected cells, particularly in the lungs of infected individuals. At present, there is no specific antiviral therapy for COVID-19 and the main treatments are supportive. In this review, we investigated the innate and acquired immune responses in patients who recovered from COVID-19, which could inform the design of prophylactic vaccines and immunotherapy for the future.

Practice GuidelineCOVID-19 and ENT Pediatric otolaryngology during the COVID-19 pandemic. Guidelines of the French Association of Pediatric Otorhinolaryngology (AFOP) and French Society of Otorhinolaryngology (SFORL).
Joint guidelines of the French Pediatric Otolaryngology Society (AFOP) and of the French Society of otorhinolaryngology-head and neck surgery (SFORL) on the management of paediatric otolaryngology patients in the context of the COVID-19 pandemic. ⋯ In children, incidence of symptomatic COVID-19 (1-5%) is low and of good prognosis. The indications for nasal flexible endoscopy should be drastically limited. If undertaken, full Personal Protective Equipment (PPE) including FFP2 masks are required, as well as use of a sheath. Saline nose wash done by caregivers other than parents at home should require PPE. Unless foreign body tracheobronchial aspiration is clinically obvious, CT-scan should be performed to confirm indication of endoscopy. Surgical indications should be limited to emergencies and to cases that cannot be delayed beyond 2 months (especially endonasal, endopharyngeal laryngo-tracheobronchial procedures). Postponement should ideally be a group decision and recorded as such in the medical file. Surgical techniques should be adapted to limit the risk of viral dissemination in the air, avoiding the use of drills, microdebriders, monopolar cautery or lasers. Continuous suction should be placed near the operating field. In case of confirmed Covid-19 cases, or suspected cases (or in some centres systematically), PPE with FFP2 mask should be worn by all staff members present in the operating room.

Stepping up infection control measures in ophthalmology during the novel coronavirus outbreak: an experience from Hong Kong.
Coronavirus disease (COVID-19) has rapidly emerged as a global health threat. The purpose of this article is to share our local experience of stepping up infection control measures in ophthalmology to minimise COVID-19 infection of both healthcare workers and patients. ⋯ We hope our initial experience in stepping up infection control measures for COVID-19 infection in ophthalmology can help ophthalmologists globally to prepare for the potential community outbreak or pandemic. In order to minimise transmission of COVID-19, ophthalmologists should work closely with local infection control teams to implement infection control measures that are appropriate for their own clinical settings.

Predicting the angiotensin converting enzyme 2 (ACE2) utilizing capability as the receptor of SARS-CoV-2.
SARS-CoV-2, the newly identified human coronavirus causing severe pneumonia pandemic, was probably originated from Chinese horseshoe bats. However, direct transmission of the virus from bats to humans is unlikely due to lack of direct contact, implying the existence of unknown intermediate hosts. ⋯ As a result, we predicted that SARS-CoV-2 tends to utilize ACE2s of various mammals, except murines, and some birds, such as pigeon. This prediction may help to screen the intermediate hosts of SARS-CoV-2.
