Brazil’s Zika outbreak has killed more than 5,000 people and infected more than 3.7 million, including many children, according to official statistics.
It has also displaced thousands of people, including thousands of schoolchildren.
A lack of vaccine and treatment has fueled the surge in the country, which is currently battling the worst outbreak in history.
The Centers for Disease Control and Prevention announced Monday that there were nearly 1.2 million cases, more than any other year in its recorded history.
In total, the country has reported more than 10,000 deaths.
The death toll has been rising for months.
Last month, the World Health Organization said that the virus had killed more people than the Ebola outbreak in West Africa did in the same time period.
