The danger of dual infection of Covid-19 and flu – VnExpress


Co-infection with flu and Covid-19 can aggravate lung damage, respiratory failure, sepsis, and double the risk of death.

RT television channel on January 3 reported that Rabin Medical Center in Petah Tikva, Israel received a pregnant female patient who was diagnosed with co-infection with influenza virus and Sars-CoV-2 immediately upon admission. Flu symptoms and Covid-19 both attack the patient’s upper respiratory tract.

According to BS.CKI Bach Thi Chinh, Medical Director of the VNVC Immunization System, the co-infection of influenza and Covid-19 among pregnant women in Israel is considered the first “double disease” case in the world clearly recorded by testing. Both flu and Covid-19 tests came back positive after multiple tests.

Both flu and Covid-19 are caused by viruses that attack the upper respiratory tract, concentrated in the pharynx and lungs, causing difficulty breathing. During pregnancy, a woman’s body changes in her immune system, lungs, and heart, making her more susceptible to serious illness and complications caused by viruses such as influenza virus or Sars-CoV-2.

“Pregnant women infected with Covid 19 will have an increased risk of premature delivery and stillbirth. On the other hand, if a pregnant woman is infected with the influenza virus, it can harm the development of the fetus. Thus, if co-infection is both Two diseases at the same time will definitely increase the risk of hospitalization and adverse complications for both mother and fetus,” warned Dr. Chinh.

In Vietnam, besides Covid-19, the current winter-spring season is also the peak flu season of the year, especially in the North. Influenza virus strains circulating in Vietnam are quite diverse, but mainly influenza A (H3N2, H1N1) and two strains of influenza B (Yamagata and Victoria). These are also strains of influenza that cause severe illness in humans.

“Co-infection with flu and Covid-19 can cause worsening of lung damage, respiratory failure, sepsis, heart damage, and even death. Flu and Covid-19 both have similar symptoms. So get vaccinated. Influenza not only plays a big role in avoiding the risk of co-infection, but also reduces the possibility of confusing symptoms, making it difficult to diagnose and treat,” added Dr.

Health organizations around the world warn that a dual pandemic of influenza and Covid-19 is likely to occur this winter, causing consequences that weaken the immune system. Research from experts at the University of California, USA, shows that people with flu and Covid-19 at the same time are twice as likely to die as people with Covid-19 alone. This is why this year the flu prevention work in many countries has been strengthened.

Bach Thi Chinh emphasized: “It is possible to simultaneously inject the Covid-19 vaccine and other preventive vaccines such as influenza, pneumococcal disease, measles, mumps, rubella, chickenpox… in the same vaccination session without needing to be vaccinated. Therefore, people should get vaccinated as soon as possible, fully and on time to avoid concurrent infection with Covid-19 and infectious diseases.”

Currently, Vietnam has new-generation quadrivalent influenza vaccines indicated to prevent seasonal influenza caused by 4 strains of influenza virus including two strains of influenza A (H1N1, H3N2) and two strains of influenza B (Yamagata, Victoria) ) for children and adults, especially the elderly, people with underlying medical conditions. Before becoming pregnant, women need to take the initiative to get vaccinated against flu and infectious diseases as soon as possible to protect the best health for themselves and their unborn baby.

In addition, according to Dr. Bach Thi Chinh, people are also at risk of co-infection with Covid-19 with other respiratory infectious diseases such as pertussis – diphtheria – tetanus, meningitis, measles – mumps – rubella , chickenpox, Japanese encephalitis… Therefore, in addition to the flu vaccine, children and adults need to be fully vaccinated with other vaccines to effectively prevent disease and “cross-immunity” with Covid-19. Improper injection schedule, insufficient dose will make the disease prevention incomplete and create an immune gap, the risk of disease overlap increases.
