Both viruses stand out for being new in the Americas, coupled with their pathogenic potential and virulence. Being positive single-stranded RNA gives the viruses a higher replication rate, making them potentially pandemic. The viruses also share other characteristics such as the vertical transmission of which zika It was also teratogenic, which is unknown from 2019-nCoV. Influenza H1N1 has no such attribute and only contributes to premature deliveries in infected pregnant women without fetal involvement. Another characteristic of the viruses is the transmission from person to person, without mediating a vector or having sexual contact, which is attributed to the circulating viral load and physical contact in addition to flugge drops dispersed in the environment close to patients. This situation causes a contagion between family members and health workers. Finally, asymptomatic cases with Zika, feverish or afebrile cases, and asymptomatic carriers have been reported. These symptoms have also been recently reported in children with no typical symptoms of infection and with a pneumonia radiological picture, which suggests the asymptomatic condition of the new coronavirus
