Flu that infects people around the globe almost every season is caused by two main types of Influenza virus – A and B. These viruses are quick to mutate, especially when they pass from animals to humans. These viruses have caused major outbreaks like the Bird flu and Swine flu.
Zika, a virus spread by mosquitos, is especially dangerous for pregnant women. The virus can pass from the mother to the fetus and cause birth defects.
SARS-1 is a virus responsible for the 2002-2004 outbreak. Spreading to more than a dozen countries, it transmitted from person-to-person inside droplets that infected people cough or sneezed out.
Ebola is caused by a deadly and highly contagious Ebola virus disease that infects humans and other non-human primates. It causes symptoms like fever, aches, fatigue, diarrhea, and vomiting.
COVID-19 is a disease caused by SARS-CoV-2 virus. It has an especially high transmission rate meaning that it easily infects new people, a long incubation period during which one has no symptoms and a high mortality rate. As of right now, there are several effective vaccines against COVID-19.
MERS-CoV was a virus first found in Saudi Arabia. Although it is not easily transmitted, 35% of people infected with MERS-CoV virus passed away.

We'd love to answer your questions about pandemic
- I passed the tests and it turned out that I am a carrier of the human papillomavirus. Does this mean I will get cancer?
In about 90% of cases, HPV leaves the body within 2 years without causing any health problems. You should consult with your doctor to decide when you will have check-ups and use barrier contraceptives.
- How common is HPV? Is there a chance of not getting sick?
According to the U.S. Centers for Disease Control and Prevention, the human papillomavirus is so common that virtually every sexually active person will at some point get an HPV infection, if not vaccinated, and be asymptomatic. But at the same time, most of the oncological diseases of the genital organs, anus and oropharynx are associated with the presence of a virus in the body.
- My little son has bronchitis. The doctor did not consider it necessary to prescribe antibiotics, and pharmacy staff refuses to sell them to me without a prescription. What to do?
In 80% of cases, bronchitis in children is not caused by bacteria, but by viruses. Antibiotics do not help in the fight against viral diseases and they are not used to prevent diseases of the respiratory system. It is worth listening to the doctor's opinion and not trying to treat your child with antibacterial drugs on your own.
- Why is zinc and vitamin D taken for covid?
Studies on the effect of high doses of dietary supplements with zinc and vitamin D on the course of coronavirus infection are very controversial. There is no evidence that vitamin D and zinc actually make you heal faster or get sick more easily.
However, both zinc and vitamin D are really important for our immune function. Considering that most of the city dwellers have a deficiency of these substances, it might be useful to take them additionally. But you need to remember that everything is good in moderation, and be sure to consult your doctor before you start taking additional vitamins and minerals.
