STAMFORD, Conn. (WTNH) — More than 1 million people have fled Ukraine, and at least 160,000 have been displaced inside the country as fighting continues between Russian and Ukrainian forces in Europe’s largest ground war since World War II.

Americares, a global health-focused humanitarian organization headquartered in Stamford, said it has sent an emergency response team to Krakow, a Polish city near the Czech Republic border.

Americares Vice President of Emergency Programs Kate Dischino said the organization is focused on “meeting the health needs of families caught in the violence of those fleeing Ukraine.”

The United Nations issued an appeal this week for $1.7 billion to help with aid efforts, estimating that 12 million people in Ukraine and 4 million refugees could need relief and protection in the coming months.

Americares is working with the World Health Organization and other response organizations to ensure all needs are covered.

“We’re getting requests from wound care supplies, IV solutions, and antibiotics, and Americares is responding,” Dischino said.

The organization is currently asking for donations toward its Ukraine Crisis Fund.
