Five new cases of Ebola in DRC
The World Health Organization's (WHO's) online Ebola dashboard reflects 5 new cases of the viral disease over the weekend, including 3 cases reported today. The outbreak total now stands at 3,398, including 2,235 fatalities.
Officials are still investigating 410 suspected cases.
The DRC's Ebola technical committee (CMRE) said in a report yesterday that two new cases over the weekend were in Beni and Musienene. The case in Musienene marks the reappearance of the virus in that village, which had gone several weeks without Ebola detection.
The CMRE also said 264,682 people have been vaccinated as of Jan 12 with Merck's rVSV-ZEBOV, and 5,684 with Johnson & Johnson's Ebola vaccine.

Minnesota confirms CWD on Pine County deer farm, linked to other farm
The Minnesota Board of Animal Health (MBAH) late last week confirmed chronic wasting disease (CWD) on a deer farm in Pine County—the first case in the county—and the case is linked to CWD investigations into a Douglas County farm that began last month.
"We identified the Pine County herd as high priority early in our investigation because our records showed it provided deer to the Douglas County herd," said MBAH Assistant Director Linda Glaser, DVM, in a Jan 10 news release. "At this point in the investigation CWD has not been detected in any of the other herds connected to Douglas County."
CWD is a deadly neurologic prion disease that affects cervids such as deer, elk, and moose. Though the disease has not yet jumped to humans, some experts fear it could mimic bovine spongiform encephalopathy ("mad cow" disease). Pine County is in east-central Minnesota, whereas Douglas County is in west-central Minnesota.
MBAH officials reported CWD detection on the Douglas County farm on Dec 10, in an 8-year-old doe. The only other deer on the farm was euthanized to prevent further CWD spread, and the site cannot house deer or elk for 5 years. The finding prompted the Minnesota Department of Natural Resources on Dec 23 to announced a 30-day mandatory emergency temporary ban on the movement of farmed white-tail deer within the state.
Officials investigated the Pine County farm because it had provided animals to the other farm in the past, including the doe that tested positive last month. The CWD-positive Pine County deer is also a doe. The farm's owners will now cull the remaining animals on the farm and test them for the disease. It likewise cannot stock cervids for 5 years.

Mandatory vaccination tied to higher measles, pertussis vaccine uptake
A study published today in Pediatrics shows that mandating vaccination in some European countries was associated with an increase in immunization rates against measles and pertussis by 2 to 4 percentage points.
Researchers used data from the WHO and 29 European countries to establish country-level vaccination policies and the annual incidence of these two infectious diseases. They found that mandatory vaccination was associated 3.71 (95% confidence interval [CI]: 1.68 to 5.74) percentage point higher prevalence of measles vaccination and a 2.14 (95% CI: 0.13 to 4.15) percentage point higher prevalence of pertussis vaccination when compared with countries that did not have mandatory vaccination.
Only 7 of 29 European countries mandated vaccination.
"In 6 of the 7 countries that had mandatory vaccination policies in place, if parents failed to meet the requirements of their country's regulations and requirements, they faced a financial penalty," the authors wrote.
Every €500 ($557 US) increase in the maximum possible penalty was associated with an increase of 0.8 percentage points for measles vaccination coverage (95% CI, 0.50 to 1.15; P ≤ .0001) and an increase of 1.1 percentage points for pertussis vaccination coverage (95% CI, 0.95 to 1.30; P ≤ .0001).
In an accompanying commentary, Sean T. O'Leary, MD, MPH, of the Children's Hospital Colorado, and Yvonne A. Maldonado, MD, of Stanford University, write that the study has implications for US vaccine policy. Unlike Europe, the US has no countrywide mandatory vaccine policies or financial penalties.
"Perhaps, vaccine mandates and fines are 1 answer, but is it possible for us also to identify effective ways to address the growing distrust of evidence-based interventions, such as vaccination?" the two wrote. "We must strive to develop an effective national approach to prevent the resurgence of highly preventable infectious diseases, using tested, multipronged approaches that still seem to be lacking."

Hungary, Slovakia, and Taiwan report avian flu in poultry
In a sign of expanding highly pathogenic H5N8 avian flu activity in European poultry, Hungary and Slovakia have reported their first outbreaks of the winter, according to notifications from the World Organization for Animal Health (OIE).
Hungary's outbreak occurred in 13-week-old fattening turkeys at a farm in Komarom-Esztergom County in the northwest. The event began on Jan 9, killing 4,500 of 53,500 birds. The remaining turkeys were slated for culling. The source of the virus is listed as unknown but could be indirect contact with wild birds. The outbreak is Hungary's first from H5N8 since 2017.
Meanwhile, Slovakia reported an outbreak in backyard birds in Nitra region in the west. The outbreak also started on Jan 9, killing 3 of 22 birds. The surviving birds were culled as part of response measures. The country also reported its last H5N8 outbreak in 2017.

Elsewhere, Taiwan reported more outbreaks involving different strains, one caused by highly pathogenic H5N2 and three from highly pathogenic H5N5, which was first detected in the country in September 2019. The H5N2 outbreak began on Dec 28 at a farm housing native chickens in Yunlin County, killing 2,432 of 23,411 birds. The outbreak is part of ongoing H5N2 activity in Taiwan that has been under way since 2015.
The three H5N5 outbreaks were detected in native chickens in two slaughterhouses in Taipei City and at a poultry farm in Yunlin County. The outbreak start dates range from Dec 27 to Dec 31, 2019, with the virus killing 1,000 of 10,895 birds. The rest were slaughtered to curb the spread of the virus.
