How nations contained recent outbreaks during the recent epidemics that weren't

Epidemics that weren’t: How countries shut down recent outbreaks


In 2018, when Ebola infected eastern Congo, it was difficult to track cases. Public health official Dr. Billy Yumaine recalls steady flows of people crossing the Ugandan border, while others hid sick family members in their homes out of fear of the authorities. The results of the tests took at least a week to come back, and health officials had a hard time keeping sick people apart while they waited.

Over 2,300 people died as a result of that outbreak, which took the nation two years to contain.

Congo faced a similar catastrophe in September 2021. Individuals from a family in North Kivu territory became sick with fevers, spewing and loose bowels, in a steady progression. Then, at that point, their neighbors ended up being debilitated, as well.

But that sparked a series of actions that Congo took after the outbreak in 2018. The patients were tested, the cases were quickly identified as a new Ebola outbreak, and 50 family contacts were immediately identified by health care workers.

After that, they spread out to check on potential patients at health centers and screened people at the busy border posts, stopping anyone who had the hemorrhagic fever symptoms. More than 1,800 blood samples were examined by local labs established in response to the previous outbreak.

It had an impact: Ebola killed only 11 people this time.

Yumaine stated, "Those people died, but we kept it to 11 deaths, where we lost thousands in the past."

You presumably didn't hear that story. You probably did not hear about the deadly Nipah virus outbreak that a doctor and her colleagues encountered last year in southern India. or the outbreak of rabies that threatened to spread throughout Tanzania's nomadic Masai communities. After a few children died, quick-thinking public health officials put it under control.

Expansions all over the world have dominated the headlines and social media feeds in recent years. There was Coronavirus, obviously, yet in addition mpox (previously known as monkeypox), cholera and resurgent polio and measles. Be that as it may, twelve additional episodes gleamed, compromised — and afterward were snuffed out. Even though it doesn't seem like it, we've learned a few things about how to do this, and sometimes we succeed.

Six non-disasters were documented in a report by the global health strategy organization Resolve to Save Lives. All of them emerged in developing nations, including those with some of the world's most fragile health systems, like Congo.

During the Covid years, cutting-edge vaccine technology and genomic sequencing have received a lot of attention, but the actions that prevented these six pandemics were steadfastly under the radar: gaining community confidence in the local health system. educating local employees on how to effectively report a suspected problem. Having funds available to distribute quickly, deploy contact tracers, or rabies vaccine a village. Expanding lab limit in regions a long way from metropolitan focuses. preparing everyone to act quickly at the first sign of trouble.

"Outbreaks don't happen because of one mistake; they occur as a result of a series of missteps," stated Dr. Tom Frieden, CEO of Resolve and a former director of the United States Centers for Disease Control and Prevention. Furthermore, the pandemics that don't occur don't occur in light of the fact that there are a progression of hindrances that will keep them from occurring."

Yumaine informed me that providing health officials in each community with training in the response would be a crucial step in containing the Ebola outbreak in Congo in 2021. The population of the Kivu region is constantly threatened with displacement and has endured decades of armed conflict and unrest. When people were told they would have to be isolated due to Ebola exposure during previous public health emergencies, they feared it was a ruse to move them off their land.

"Previously, it was consistently individuals from Kinshasa who were accompanying these messages," he expressed, alluding to the nation's capital. But this time, people were more willing to listen and be tested because the instructions about lockdowns and isolation came from reliable sources.

He stated, "We were able to give local control to local people because they were trained."

People suspected of having Ebola could be tested in a day or two thanks to the establishment of labs in the area, as opposed to waiting a week or more for samples to be shipped over 1,600 miles to Kinshasa.

In 2018, an outbreak of Nipah, a virus carried by fruit bats, occurred in the southern Indian state of Kerala. Dr. Chandni Sajeevan, head of emergency medicine at the Kozhikode Government Medical College hospital, was in charge of the response. Seventeen of the 18 individuals tainted kicked the bucket, including a youthful learner nurture who really focused on the primary casualties.

Chandni stated, "It was something very frightening." By dressing in the "moon suits" that seemed so foreign in the pre-COVID era, the hospital staff received a crash course in intensive infection control. The loss of a colleague broke the nurses' hearts.

Chandni and her team were relieved when, in 2021, the bat breeding season enended without any infections. A 12-year-old boy with a high fever was brought to a clinic by his parents in May, during the worst COVID outbreak in India. He was sent to the next clinic because that one was full, and he tested negative for Covid at the third clinic.

However, an attentive doctor noticed that the child had encephalitis. He gave the national virology laboratory a sample. It quickly proved that this was a brand-new Nipah virus infection. The child may have exposed several hundred people, including dozens of medical professionals, by that time.

The procedure that Chandni and her coworkers had implemented following the outbreak in 2018: isolation facilities, moon suits, and Nipah and COVID testing for those with fevers. She held daily news briefings to dispel rumors, keep the public safe from bats and their droppings, which litter coconut groves where children play, and keep them away from people who might be sick. For surveillance purposes, teams were sent out to catch bats. 21 days of quarantine were imposed on everyone who had come into contact with the sick boy.

She stated, "This time, everyone, ambulance drivers, elevator operators, security guards — they knew about Nipah and how to behave not to spread it."
