In the capital, Baghdad, dozens of people were lined up for ambulance in a packed street.
“I’m waiting for a car to take me to hospital,” said Ayman Abdullah, 40, a carpenter.
“I’m sick, I’m hungry, I’ve lost my job and I want my children to have a better life.
They are sick.
I don’t know what else to do.”
Baghdad’s Health Ministry said around 50 people had been treated in the city, and more than 1,500 others were being monitored for the virus.
Iraqi Prime Minister Nouri al-Maliki has warned that more than a third of the country’s population could die of the virus, and he has ordered a massive health blitz to combat it.
The latest flare-up came as Baghdad is preparing to hold a second public health conference for the first time in a week.
At least 16 people died on Thursday in Baghdad’s main shopping street, the Mardan district, as people waited for ambulants to pick them up, witnesses said.
Another 10 people were injured on Thursday when a car careered into a crowd of people waiting for an ambulance, witnesses told Al Jazeera.
“It was a car accident and the person was killed,” one witness told Al-Jazeera.
A doctor treating a patient on the second day of the public health campaign said the virus was spreading rapidly among people who had just returned from abroad.
“They’ve returned, so they are not as well protected as they were,” said Dr Saadat, a doctor who treated people on Thursday.
“It’s the first day of a public health blitz, and it’s spreading fast.
We are not yet able to control it.”
Medical officials said more than 500 people were being treated in Baghdad and the capital’s main hospitals, including intensive care units and specialist units, and about 30,000 had tested positive for the coronavirus.
Health ministry spokesman Abdul Qadir al-Hussaini said it was too early to say how many people had died from the virus but that the number of people in intensive care had increased dramatically.
“The number of patients is now more than 10,000.
It is too early for us to tell how many have died,” he said.
“The virus is spreading rapidly in the country, and people are in a situation where they need to be isolated from others.”
Meanwhile, the United Nations warned that up to 200,000 Iraqis could be infected with the virus this month.
More than 10 million people are estimated to be infected in the region, and the country is experiencing a sharp increase in cases.
At the peak of the outbreak, about 2,700 people were believed to be in the epidemic zone, the US Centers for Disease Control and Prevention (CDC) said on Friday.
The WHO warned on Friday that there were fears the virus could spread to neighbouring countries in Central Asia and Central Africa.
