COVID-19 and Internet Hospital Development in China.

Since 2018, the access policy for Internet hospitals has been issued in China. So far, thousands of Internet hospitals have been approved to operate and have played a significant role during the COVID-19 pandemic. While front-line hospitals strive to treat patients, Internet hospitals take the responsibility to guide patients to seek appropriate medical treatment and meet the urgent needs of chronic patients through online medical follow-up, payment, and drug distribution.

Between Ambitious Strategies and Reality: The African Union Strategy on COVID-19 Vaccine.

A key learning lesson from country responses to COVID-19 pandemic was the impact of the strategies that are followed on combating the pandemic. Since the development of different vaccines and their supply globally, most countries have developed their own strategies to effectively provide sufficient doses for their population and start the vaccination process with the best outcomes. In this perspective, we review the African Union vaccination strategy by exploring the implementation of the strategy and its outcomes.

Geospatial model of COVID-19 spreading and vaccination with event Gillespie algorithm.

We have developed a mathematical model and stochastic numerical simulation for the transmission of COVID-19 and other similar infectious diseases that accounts for the geographic distribution of population density, detailed down to the level of location of individuals, and age-structured contact rates. Our analytical framework includes a surrogate model optimization process to rapidly fit the parameters of the model to the observed epidemic curves for cases, hospitalizations, and deaths. This toolkit (the model, the simulation code, and the optimizer) is a useful tool for policy makers and epidemic response teams, who can use it to forecast epidemic development scenarios in local settings (at the scale of cities to large countries) and design optimal response strategies.

COVID-19 Outbreak Management and Vaccination Strategy in The United States of America.

Four months after the first case of COVID-19 was reported in the United States, the SARS-CoV-2 virus had spread to more than 90% of all counties. Although the transmission of the virus can be grossly mitigated through non-pharmaceutical interventions and public health measures, risks of future outbreaks, emergence of more infectious variants, and disruptions to socio-economic life will probably remain until effective vaccines are administered to large portions of the global population. An exceptional collaboration between governments and the scientific community has led to the authorization of eight vaccines globally for full use, four of which were funded and developed in the United States.
