Influenza peaks around June and December in Singapore every year. Facing an ageing population, hospitals in Singapore have been constantly reaching maximum bed occupancy. The ability to be able to make early decisions during peak periods is important. Tan Tock Seng Hospital is the second largest adult acute care general hospital in Singapore. Pneumonia-related emergency department (ED) admissions are a huge burden to the hospital's resources. The number of cases vary year on year as it depends on seasonal vaccine effectiveness and the population's immunity to the circulating strain.

Rabies is a zoonotic, neglected viral disease. Every 10 minutes, the world loses a life, especially children, to dog-mediated rabies. Yet it is 100% preventable. Africa, including Nigeria, has major share of the disease. Eradication of human rabies relies majorly on control of rabies in animals and this cannot be achieved without good surveillance system of the disease in animal, especially dogs. There is little or no information as to whether the surveillance system in Nigeria is effective.

Approximately 100,000 New York City (NYC) residents are currently diagnosed with chronic hepatitis B virus (HBV) infection.1 Routine monitoring and treatment, where indicated, are necessary to reduce HBV disease progression. Using the 2017 European Association for the Study of the Liver (EASL) 2 guidelines on HBV infection management, we developed a surveillance-based definition for treatment eligibility.

Sequence-informed surveillance is now recognized as an important extension to the monitoring of rapidly evolving pathogens [2]. This includes phylogeography, a field that studies the geographical lineages of species including viruses [3] by using sequence data (and relevant metadata such as sampling location). This work relies on bioinformatics knowledge. For example, the user first needs to find a relevant sequence database, navigate through it, and use proper search parameters to obtain the desired data.
