What Is Already Known About This Topic?: After the initial coronavirus disease 2019 (COVID-19) outbreak in Wuhan, China, the outbreaks during the dynamic-zero policy period in the mainland of China have not been systematically documented.
What Is Added By This Report?: We summarized the characteristics of 74 imported COVID-19 outbreaks between March 19, 2020 and December 31, 2021. All outbreaks of early severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants were successfully contained with the aid of nucleic acid testing, modern communication technologies, and non-pharmacological interventions.
What Are The Implications For Public Health Practice?: These findings provide us with confidence for the containment of future emerging infectious diseases alike at early stages to prevent pandemics or to win time to gain experience, develop vaccines and drugs, vaccinate people, and wait for the possible lessening of the virus' pathogenicity.

The continual evolution of SARS-CoV-2 has significantly influenced the global response to the COVID-19 pandemic, with the emergence of highly transmissible and immune-evasive variants posing persistent challenges. The Omicron variant, first identified in November 2021, rapidly replaced the Delta variant, becoming the predominant strain worldwide. In Florida, Omicron was first detected in December 2021, leading to an unprecedented surge in cases that surpassed all prior waves, despite extensive vaccination efforts.

Background: This study analyzed the epidemiological trends of three significant respiratory infectious diseases in Taiwan: invasive pneumococcal disease (IPD), influenza with severe complications, and tuberculosis during post-COVID-19 pandemic period.
Methods: We utilized data from Taiwan's Centers for Disease Control and Prevention (CDC) website and classified the COVID-19 prevention policies into three phases for the year 2021, 2022, and 2023. We then performed a statistical analysis of reported case numbers for the three respiratory diseases during the 3-year period using the Kruskal-Wallis test, followed by joinpoint regression model for the identification of seasonal distribution and variation.

Pakistan has experienced a total of six COVID-19 waves throughout the pandemic, each driven by distinct SARS-CoV-2 lineages. This study explores the introduction of Omicron lineage BA.4 into Pakistan, which contributed to the sixth wave between June and September 2022.

Background: Several variants of SARS-CoV-2 have a demonstrated impact on public health, including high and increased transmissibility, severity of infection, and immune escape. Therefore, this study aimed to determine the SARS-CoV-2 lineages and better characterize the dynamics of the pandemic during the different waves in Guinea.
Methods: Whole genome sequencing of 363 samples with PCR cycle threshold (Ct) values under thirty was undertaken between May 2020 and May 2023.

This article seeks to highlight an aspect of the illegal pharmaceutical trade in the Caribbean. With the advent of COVID-19 there has been a shortage of a number of drugs in the formal sector. This is largely due to restrictions on foreign exchange, importation delays and sensationalized reporting of unrecommended drugs having a curative effect on COVID-19 patients.
