NEW YORK -- Could this nasty flu season finally be winding down? U.S. health officials on Friday said fewer visits to the doctor last week were for fever, cough and other flu symptoms than during the previous two weeks. Flu-like illnesses accounted for 1 out of 16 doctor visits last week, while the number of states reporting high patient traffic for the flu also dropped, to 39 from 43. 
 
 Officials at the Centers for Disease Control and Prevention (CDC) said they're cautious about saying flu season has peaked but called the downturn encouraging. 
 
 "It does like the peak is behind us now," said Dr. Daniel Jernigan, director of the CDC's Influenza Division. Even so, he warned, "there is certainly a fair amount of influenza to go this season -- probably until mid-April." 
 
 Flu season usually peaks in February, but this season started early and surged for months. It has been driven by a formidable type of flu that tends to cause more hospitalizations and deaths. This year's flu vaccine is estimated to be only 25 percent effective against the H3N2 virus. 
 
 "H3N2 affects more older folks, with very high hospitalization and death rates," Jernigan said, while influenza B, which is now becoming more prevalent, tends to affect younger people. Overall, the flu vaccine has been more effective for children than adults this year, reducing illness by 59 percent among kids ages 6 months to 8 years old. 
 
 The CDC reports 13 more children died of the flu last week, bringing the number of pediatric flu deaths to 97 this season. 
 
 Even at this point in the season, health officials recommend people get a flu shot if they haven't already. 
 
 "There's still, potentially, eight weeks left of the flu season, and the CDC is saying, 'go and get the flu shot,'" CBS News' chief medical correspondent Dr. Jon LaPook said recently. "Overall, about a third of the people who got the flu vaccine were protected, but in kids under 9, almost two-thirds were protected against influenza." ||||| CLOSE The CDC reported dozens of children have died this flu season, the worst in a decade.

 The worst flu season in a decade continues to take a grim toll, with 22 more child deaths reported Friday, bringing the total to 84. 
 
 The latest update by the federal Centers for Disease Control and Prevention also shows that the flu remained widespread in 48 states. 
 
 The newly listed child deaths are the most reported in any week this harsh flu season, but they occurred over several weeks, the report said. The overall count of 84 child deaths nearly matches the 86 reported by this time in 2015, during a severe season that ended up killing 148 children, CDC spokeswoman Kristen Nordlund said. 
 
 An estimated 56,000 people, mostly older adults, died that year. The CDC does not keep exact counts of adult flu deaths, but said that nearly 10% of all newly reported deaths in the country were due to influenza and pneumonia. Flu hospitalization rates among adults over age 50 also remained high.

 Friday's report showed one inkling of hope: The rate at which people visited doctors for flu-like illness stopped rising, after reaching peaks not seen since the swine flu pandemic of 2009. Such visits made up 7.5% of trips to doctors, down slightly from 7.7% the week before. 
 
 "It would be too early to say that we’ve peaked," Nordlund said. "We need to see more data, but that is something we are definitely hopeful for." 
 
 In a press conference Thursday about flu vaccines, acting CDC director Anne Schuchat said this flu season is far from over, even after 12 weeks of unusually persistent coast-to-coast misery. 
 
 “This flu season continues to be extremely challenging and intense, with very high levels of office visits for flu and hospitalization rates, all indications that flu activity is high and likely to continue for several more weeks,” she said. 
 
 This year's flu vaccines are preventing about 36% of flu cases in vaccinated people but are working better, at a rate of about 59%, in young children, the CDC reported Thursday. The vaccines are less effective, about 25%, at preventing illnesses caused by the dominant virus behind this year's epidemic, the report said. 
 
 But most of the children who have died this year have not been vaccinated, the report said. That also has been true for children who died in previous years, according to a study published this week.

 The worst flu season in a decade is still not over, with 13 new children deaths reported after more than three months of unusually persistent misery across the U.S. 
 
 The numbers were "encouraging," especially the data showing a decline in visits to the doctor's office for anyone with flu-like symptoms, said CDC spokeswoman Kristin Nordlund. These visits made up 6.4% of trips to the doctor, down from 7.5% of visits the previous week. 
 
 "It looks like we may have reached the peak of flu season," says Nordlund. 
 
 The decrease in child deaths from 22 the week before by itself was not necessarily a sign the severe flu season was abating, however, as each week's total from the Centers for Disease Control and Prevention includes deaths from earlier in the season. 
 
 Even though there was a decrease in the number of states reporting high levels of flu, more than half of the country is still reporting high levels of activity. There was also an increase in reports of the less deadly B strain. 
 
 That leads Nordlund to note, "it looks like we still have many more weeks of flu season to go," adding that it could last until mid-April. 
 
 The flu remained widespread in 48 states, according to the CDC's latest report Friday. In the last severe flu season, during 2014-2015, 148 children died. The flu also killed an estimated 56,000 people, mostly older adults, that season. 
 
 Most of the children who have died this year, as in past years, have not been vaccinated. The CDC does not keep exact counts of adult flu deaths. 
 
 All 10 regions reported flu-like illness reports that were at or above baseline levels in the areas. New York City, Washington, D.C., Puerto Rico and 39 states experienced high flu-like visits. 
 
 It's definitely not too late to get a flu shot, which remains highly recommended. "As long as flu is circulating," you can catch the flu so the vaccine is recommended.

– "It does like the peak is behind us now," CBS News quotes Dr. Dan Jernigan as saying. But the director of the CDC's Influenza Division says that doesn't mean we're out of the woods yet, warning there's still "a fair amount of influenza to go." Jernigan says this flu season, which has been the worst in a decade, could continue until mid-April. And despite signs the flu is finally letting up, it's still doing plenty of damage. The share of doctor's visits related to the flu dropped from 7.5% last to week to 6.4% this week, USA Today reports. And the number of states with high patient traffic related to the flu dropped from 43 to 39. Another 13 children were reported dead from the flu this week—bringing the total this flu season to 97—but that's down from the 22 child deaths reported last week. While this year's flu vaccine is only 36% effective overall, it's 59% effective in children. Most the of children reported killed by the flu this week had not been vaccinated, and experts say parents should still be getting their children vaccinated even this far into the flu season. Meanwhile, NBC News looks at why experts believe next year's flu vaccine will be mediocre at best.
