WORCESTER - During a media briefing on Friday, January 14, Worcester Medical Director Michael Hirsh said the Omicron variant now accounts for 96 percent of COVID-19 cases across Massachusetts and is the dominating cause of increasing stress on hospitals.
Over the last week, the UMass and Saint Vincent Hospital systems saw an increase of 91 admitted patients with COVID-19, which is now 349 current inpatients.
While 28 patients with COVID-19 died in the two hospital systems over the last week, the number of ICU patients still increased by three, to 60 total ICU patients. Meanwhile, around 45 percent of pediatric inpatients at UMass Memorial Hospital are COVID-19 positive, according to Hirsh.
Hirsh also discussed how COVID-19 positive patients can put strains on the available capacity of hospitals due to isolation requirements. Without a single-bed room available, a single patient can require isolation in a double-bed room, rendering the second bed unusable. He said the experience is especially difficult for pediatric patients, who are isolated with only one parent able to visit at a time. Pediatric patients also cannot make use of he resources available, such as play rooms, which can help alleviate the stress of hospitalization for children.
Hirsh also discussed statistics about those vaccinated who become infected, called breakthrough cases. Hirsh said the amount of viral load brought by the Omicron variant is delivering a greater number of breakthrough cases.
Viral load is the detectable amount of virus found in the body during infection.
During the Delta variant’s dominance, just 20 percent of those hospitalized were vaccinated. The Omicron variant, which carries a higher viral load, has seen that increase to 50 percent. However, of those breakthrough cases, only 10 percent received a booster shot.
Hirsh said the results show the booster is proving to be effective against serious illness.
Worcester City Manager Ed Augustus reported that the seven-day average of new daily cases increased to 683 cases per day, compared to 501 in the week prior. New confirmed positive cases in Worcester over the last week was 4,786. Four Worcester residents died from disease caused by the virus this week, bringing the total to 482.
The daily number of cases exceeds 300 in each of the last 11 days.
Augustus drew comparison to the surge period in December 2000 and January 2001, which saw a peak of 195 cases per day over a 7-day average.
On Friday alone, the number of cases reported was 413, which may be a sign of the surge fading. Earlier in the week, there were daily totals of up to 1,100 new cases in a single day.
Hirsh agreed there is a reason for cautious optimism, but said continued vigilance was necessary to support healthcare workers and relieve the intense stress on the hospital system. The history of the virus has shown that new hospital admissions continue for for weeks after the discovery of cases as infection becomes illness and a portion of the ill require hospitalization.
Hirsh said he expects to see cases start to come down, but the number of hospitalizations, ICU patients and deaths increase for another three or four weeks.
The peak of new cases may start to decrease over the weekend, but hospitals will see an increase of disease persist
Hirsh added that hundreds of workers are out of work in both the UMass and Saint Vincent hospital systems, causing double shifts, assignments below optimal ratios and long waiting time in the emergency department.
Augustus also reported that the Worcester Fire Department has 20 positive cases within its employees, with eight tests pending and another 20 in quarantine. The Fire Department is using rapid tests before a firefighter begins a shift to prevent further exposure. Fourteen tested positive before their shift. Over the last 30 days, 108 employees of the Fire Department, 28 percent of its total staff, tested positive.
The Worcester Police Department has 54 active cases with 16 percent of its staff testing positive in the last 30 days.
Augustus also reported that 120,847 residents in Worcester, 59 percent, are fully vaccinated and 44,533 residents received the booster, 36 percent.
Worcester lags behind both the statewide percentage for those boosted, 46 percent, and the nationwide rate of 37 percent.
