Connell School of Nursing Assistant Professor Nadia Abuelezam
In the wake of the first case of the coronavirus reported in Massachusetts earlier this month, Connell School of Nursing Assistant Professor Nadia Abuelezam compiled a concise list of facts about the virus for the school website in the wake of 鈥渁 barrage of news and social media posts full of data, terminology, and information that was difficult to understand.鈥�
Abuelezam, an epidemiologist, 聽said the summary was intended to provide a better understanding of the technical side of coronavirus, and how to reduce the risk of infection鈥攔egularly washing hands with soap and warm water, covering coughs and sneezes, staying home if you feel sick.
Abuelezam explained that the incubation period for the virus is estimated to be from two to 14 days, and that its latent period鈥攖he time from when a person is infected to when he or she can infect other people鈥攊s still largely unknown.
She also described the epidemiological terms prevalence鈥攁 figure, usually presented as a percentage, that can be understood as the proportion of the population with the disease of interest鈥攁nd incidence, a rate indicating the number of new cases occurring in a population over a certain period of time, which conveys the risk of contracting the disease. At present, she said, the low number of cases in the U.S. means the prevalence is currently negligible; incidence can only be calculated with more information on the total number of infections and the total population at risk.
聽Another important term, Abuelezam noted, is the basic reproductive number, or the number of new cases likely stemming from one infectious case: When the basic reproductive number is greater than 1, the disease is expected to spread.
鈥淚t鈥檚 important to note that the basic reproductive number is very context-specific, so it cannot be extrapolated across populations and countries,鈥� she said. 鈥淭he basic reproductive number in Wuhan, China, the epicenter of the epidemic, is currently estimated to be 2.68, meaning two to three people are infected from every infected person in this particular area.鈥�
For context, Abuelezam pointed out that the basic reproductive number for the flu is estimated at 1-2 and for measles 12-13.
Abuelezam urged readers to stay up to date on developments concerning the coronavirus by consulting reliable sources and to follow recommendations and guidelines from public health experts.
鈥淢ore than anything at the beginning of any epidemic, including this one, it鈥檚 important to stay calm and stay healthy.鈥�
