Coronavirus Disease 2019 (COVID-19) outbreak in Wuhan, China, spread rapidly throughout China, and gradually to some countries abroad. How to control the development of the epidemic? Early diagnosis is one of the important contents in prevention and control. COVID-19 patients with early mild pneumonia often lack typical evidence to make a definitive diagnosis. Based on the analysis of the cases of 4 patients, this article finds that early diagnosis requires a combination of epidemiology, clinical manifestations, imaging, and etiology, with particular emphasis on epidemiology history and chest CT manifestations.
When it comes to coordinating the fight against contagious diseases, the WHO is the most important international actor. This article presents the International Health Regulations 2005; the WHO’s legal basis for coordinating the work to counter transboundary contagious diseases. Whereas in principle the International Health Regulations 2005 vest in the WHO the power to ensure a coordinated response against these diseases, in practice experiences show that, as a general rule, states only half-heartedly follow WHO recommendations. This article argues that there are three important reasons why the WHO’s fight against transboundary contagious diseases has not been successful and it puts forward proposals for ways of remedying these weaknesses.
Awareness and attentiveness have implications for the acceptance and adoption of disease prevention and control measures. Social media posts provide a record of the public’s attention to an outbreak. To measure the attention of Chinese netizens to COVID-19, a pre-established nationally representative cohort of Weibo users was searched for COVID-19-related keywords in their posts.
COVID-19-related posts (N=1101) were retrieved from a longitudinal cohort of 52,268 randomly sampled Weibo accounts (December 31, 2019 – February 12, 2020).
Attention to COVID-19 was limited prior to China openly acknowledging human-to-human transmission on January 20. Following this date, attention quickly increased and has remained high over time. Particularly high levels of social media traffic appeared around when Wuhan was first placed in quarantine (January 23-24, 8-9% of the overall posts), when a scandal associated with the Red Cross Society of China occurred (February 1, 8%), and following the death of Dr. Li Wenliang (February 6-7, 11%), one of the whistleblowers reprimanded by the Chinese police in early January for discussing this outbreak online.
Limited early warnings represent missed opportunities to engage citizens earlier in the outbreak. Governments should more proactively communicate early warnings to the public in a transparent manner.
The outbreak of coronavirus disease 2019 (COVID-19) caused by the virus SARS-CoV-2 is expanding globally. South Korea is one of the countries most affected by COVID-19 from the very early stages of this pandemic. Explosive outbreaks occurred across South Korea in the first two months, and efforts to control this new virus have involved everyone across the country. To curb the transmission of the virus, health care professionals, committees, and governments have combined many approaches, such as extensive COVID-19 screening, effective patient triage, the transparent provision of information, and the use of information technology. This experience could provide some valuable ideas and lessons to others who are fighting against COVID-19.
The COVID-19 outbreak is on-going in China. Here Boltzmann function-based analyses reveal the potential total numbers of COVID-19 deaths in China, Hubei Province, outside Hubei, Wuhan City and outside Wuhan, being 3260 (95% CI 3187, 3394), 110 (109, 112), 3174 (3095, 3270), 2550 (2494, 2621) and 617 (607, 632), respectively.
Italy is fighting against one of the worst medical emergency since the 1918 Spanish Flu. Pressure on the hospitals is tremendous as for official data on March 14th: 8372 admitted in hospitals, 1518 in ICU, 1441 deaths (175 more than the day before). Unfortunately hospitals are not prepared: even where a plan for massive influx of patients is present, it usually focuses on sudden onset disaster trauma victims (the most probable case scenario), and it has not been tested, validated or propagated to the staff. Despite this, the All Hazards Approach (AHA) for management of major incidents and disasters is still valid and the “4S” theory for surge capacity can guide to respond to this disaster.
