Late last year, what is thought to be a bat-associated coronavirus infected humans in Wuhan, a city of 11 million in China, possibly after a stopover in illegally traded pangolins—setting off a global pandemic. This kind of thing has happened before—with AIDS, SARS, and MERS, for example. Much remains unknown about the biology of COVID-19, which is alarmingly communicable by people with few or no symptoms. But an epidemic is only part biology. It is also driven by cultural factors, and urbanization is a crucial aspect. As sites of large gatherings and dense living conditions, cities offer the perfect settings for the spread of infection, yet their role seems to have often gone unremarked in discussions of the pandemic.

On May 6, Médecins Sans Frontières (MSF) announced it had started to treat COVID-19 patients in Tijuana, in northwestern Mexico. Tijuana, which is on the border with San Diego, has the greatest number of cases in Mexico and one of the highest death rates.

“We will be providing support to health institutions [by] relieving the hospital burden in Tijuana,” said Maria Rodríguez Rado, MSF’s COVID-19 Emergency Response Coordinator in Mexico, according to the group’s website. “Through this support, we want to relieve the enormous workload of health workers who are responding to this pandemic and help alleviate the suffering of patients.”

The move is welcome. Across Central America, megacities such as Guatemala City, Tegucigalpa in Honduras, and Managua in Nicaragua are vulnerable to the rapid spread of COVID-19.

Weeks before most of the world began to take the spread of COVID-19 seriously, Africa was already threatened by another plague, the biggest locust outbreak in the last 70 years. Locusts swarmed into Ethiopia, Kenya, Somalia, Uganda, and South Sudan in January and February this year. Those hordes of voracious locusts laid eggs, and now the second wave, 20 times the size of the first group, is arriving. According to Locust Watch, “The current situation in East Africa remains extremely alarming as more swarms form and mature in northern and central Kenya, southern Ethiopia, and probably in Somalia.”

Former Vice President Biden’s recent Foreign Affairs article on his proposed presidential policies hit on all major hot spots of U.S. interest globally but one, said Mike Sfraga, director of the Wilson Center’s Global Risk and Resilience Program and Polar Institute, in a recent episode of Wilson Center NOW.

“The Arctic should be a part of the foreign policy dynamic of the United States,” said Sfraga. Global politics, economics, security, and the environment connect in countless ways throughout the region, only some of which show up in headlines.

Since the onset of the pandemic, nurses and midwives have been asked in some facilities to work without personal protective equipment. Nurses have been sent home and lost their jobs simply because they insisted on following evidence-based practices, such as wearing masks. Some question whether the masks, gloves, gowns, and other commodities in short supply are more important than nurses who question the ethics of showing up when essentials aren’t available.

“While COVID-19 has wreaked havoc the world over, history has proven, and recent data agrees that the hardest hit will be the world’s women and girls and populations already impacted by racism and discrimination,” said Sarah Barnes, Project Director of the Maternal Health Initiative and Women and Gender Advisor at the Wilson Center, at a recent event on the impact of COVID-19 on race and gender inequities. Coronavirus has hurt women and girls in many ways. Among them, women have been pushed back into the home.  And healthcare workers and caregivers who are mostly women are jeopardizing their own health, caring for others.

COVID-19 isn’t the only problem going viral. Economic insecurity is driving gold prices to record highs around $1,700 per ounce, causing levels of global mercury pollution to rise too. In the United States coal-fired power plants drive mercury pollution, but globally, the leading cause is small-scale ‘artisanal’ gold mining. Roughly 30 million men, women, and children in poor countries depend on mining for subsistence incomes. Unfortunately, the cheapest and easiest way to mine gold uses mercury, a highly toxic heavy metal the United Nations is striving to eliminate.
