Having a higher number of sexual partners, being a woman in a partnership with an infected man and having frequent symptomatic recurrences after primary infection are included.
Though the primary infection heals completely, rarely leaving a scar, the virus that caused it remains in the body.
Since primary infections are more likely than non-primary infections to cause symptoms at birth and long-term disability, especially severe disability, there remains an urgent need for interventions that can prevent primary CMV infections among pregnant women.
These viruses cause a primary infection and can establish latent infection with reactivation if altered immunity develops.
In the west HCMV infects 2 to 4% of pregnant women for the first time as a primary infection during pregnancy, and it is transmitted to the foetus, resulting in a congenital infection in 40% of these pregnant women.5,8 However, in Pakistan the number of pregnant women infected during pregnancy is not known, but is most probably much higher.2 Congenital CMV in low-and middle-income countries and is mostly due to secondary maternal infections; whereas, in western settings with moderate levels of seroprevalence (70% in USA) 25% of congenital CMV are due to primary and 75% due to secondary maternal infections, in countries where seroprevalence is relatively low (50% European countries), primary and secondary infections contribute equally for occurrence of congenital CMV infection.9

(4) This is particularly important for detection of co-infections, which can remain undetected as they are masked behind symptoms of the dominant, or diagnosed, primary infection. These "silent" infections may prolong patients' exposure to pathogens and impede the efficacy of the treatment regime, affecting their recovery; therefore, diagnosis of all pathogens present is paramount for prescribing of optimal treatments, based on specific infection and reported resistance indications.
During maternal primary infection, and to a lesser extent during recurrent infection, CMV can translocate the placental barrier and can cause infection of the developing fetus [6, 7].
