The woman has now given birth to her child, who does not appear to have caught the rash-causing virus from the mother.
CDC released limited information on the case, including where in the US the woman was based. It’s also unclear when the woman was infected, or exactly when she gave birth.
Health officials said both were ‘doing well’, but the nation’s top infectious diseases expert Dr Anthony Fauci warned Tuesday that pregnant woman may face a ‘profound risk’ from the virus.
A maternity doctor told DailyMail.com that women in the early stages of pregnancy faced the biggest risk from monkeypox. The mother may have been in the final stages of her pregnancy when infected, as she recently gave birth.
The newborn received immune globin, an infusion of antibodies capable of fighting diseases including monkeypox, officials said. It is not clear what treatment the mother received.
It is the first infection to be detected in a pregnant woman in the United States, and comes after America recorded its first two infections in children last week. The pediatric cases were unrelated and detected in California and Washington DC
There are currently 3,591 monkeypox infections confirmed in America — the second biggest outbreak in the world behind Spain’s 3,738 cases.

Dr. John Brooks, chief medical officer in the CDC’s monkeypox response, revealed the case during a webinar with the Infectious Diseases Society of America Saturday.
‘There has been a case of a pregnant woman who delivered,’ Brooks said.
‘The neonate received the IG prophylactically (immune globin given to prevent disease). Both mom and baby are doing well.’
CDC official confirmed the case to DailyMail.com. Their website warns pregnant women are ‘more likely to get seriously ill or die’ from monkeypox.
Timeline of monkeypox in the United States
1958: Monkeypox is discovered when an outbreak of pox-like disease occurred in monkeys kept for research.
1970: First human case of the disease is recorded in the Democratic Republic of Congo. It was later detected in a number of other central and western African countries.
2003: America’s former largest monkeypox outbreak occurs. A total of 47 people are infected after having contact with pet prairie dogs that picked up the disease at a farm.
July, 2021: Monkeypox case detected in the US in a citizen who had recently returned from Nigeria.
November, 2021: Monkeypox is detected in another US resident who recently returned from Nigeria.
May, 2022: A man in Massachusetts is diagnosed with monkeypox, becoming the first case in the current outbreak. There are now more than 3,000 cases nationwide.
July, 2022: Two children and a pregnant women test positive for monkeypox, as the disease spreads to other groups. The children were in California and traveling through Washington DC, it was not clear where the woman was.
Fauci — the top infectious diseases expert in the US — warned in an interview about yesterday that pregnant women were among those more at risk from monkeypox.
He told NPR: ‘We’ve got to understand the modality of transmission, the manifestations, also the risk for people like children and pregnant women. There’s really a profound risk.
‘Right now, thank goodness, we have a report of only two cases in children, but they’re all at risk populations.’
Dr Daniel Roshan, a maternal-fetal medicine expert at Rosh Maternal and Fetal Medicine in New York, told DailyMail.com that pregnant women and their babies faced the greatest risk from monkeypox early in pregnancy because the babies organs were still developing, raising the risk of birth defects.
In the later stages he said babies are more at risk of catching the virus because there is more blood flow to them, but less likely to suffer birth defects as most organs are already developed.
He told DailyMail.com: ‘If they catch the virus in the first ten weeks of pregnancy since the baby has just started to develop there is a greater risk of congenital abnormalities.
‘[But] in the third trimester there is more blood flow from placenta to the fetus and it’s easier to get the virus.’
Pregnant women who catch monkeypox can pass it on to their babies in the womb via the placenta. It can also be transmitted once a child is born through close contact — such as cuddles — and there may be a risk of it being passed on via the breastmilk.
Roshan said immune globin would be administered to a pregnant woman who caught monkeypox to help fight off the infection.
Asked how the parent became infected, Roshan said this was likely via close contact with an infected patient.
He advised pregnant women to observe ‘normal protocol’ to avoid becoming infected. ‘I would say they should just be careful with the contact,’ he said. ‘Stay away from people with rashes or fever, and follow personal hygiene.’
The CDC says that babies born to pregnant women should be washed immediately after birth with wipes and soapy water.
In guidance published this week, they add doctors should then decide whether to administer a vaccine to the child or antiviral.
Infants must then be monitored for 21 days — during which time they should be looked after by a carer or family member — to ensure they have not caught the virus.
Infected mothers should steer clear of their children until all the lesions triggered by monkeypox have scabbed over, and the scabs have fallen off.
Dr. John Brooks, chief medical officer in the CDC’s monkeypox response, revealed the case in a pregnant woman during a webinar on Saturday. Dr. Anthony Fauci, America’s leading infectious diseases expert, said pregnant women were at ‘profound risk’ from the virus
Medical literature shows monkeypox infections in pregnant women have previously led to miscarriage, stillbirth, early delivery and infection in the womb.
But it is not clear how often these occur, because so few pregnant women have previously been infected.
A 2017 study that tracked four pregnant women with the disease in the Democratic Republic of Congo found two miscarried there babies and there was one fetal death.
Smallpox, monkeypox’s now-eradicated cousin, was also more severe among pregnant women.
Last week the CDC revealed America’s first two cases of monkeypox had been detected in children as the virus spreads to other groups.
One is a toddler from California, while the other is an infant who was traveling through Washington DC when the case was detected. Neither had contact with each other.
It is thought both children likely caught the virus from ‘household contacts’, which includes people they live with and visitors to their home.
Dr Rochelle Walensky, the CDC’s director, said the children both had contact with gay or bisexual men — the community where most cases are being detected in the current outbreak.
They have received the antiviral TPOXX, which can help stop an infection in its tracks by interfering with the virus’s maturation.
Until now monkeypox infections have been almost exclusively among gay or bisexual men.
But a top expert has warned that the virus has likely already spread to other groups, but was not being detected among them yet due to a lack of testing.
The World Health Organization warns that pregnant women are more at risk from monkeypox.
Scientific studies suggest that between three and ten percent of children infected with monkeypox die from the disease, depending on the strain they catch.
