It's no enjoyment being sick especially during pregnancy when you're likely to worry about your increasing baby's health as much as your own. Happily, you may already be immune to a number of contagious diseases. And thanks to a successful vaccination program, rubella– the most dangerous infection of all for a developing little one – is now very rare in this country.

You can also take comfort in the fact that most babies aren't injured if their mother gets an infection during pregnancy. However some infections can be transmitted to babies through the placenta or during birth and when that happens, it may have serious penalty for the baby. What's more, some infections can make you sicker if you get them when you're pregnant or may lead to complications like preterm labor.

You can't avoid all sources of infection even as you're pregnant. But you can take certain steps to make it less likely that you'll get sick and to reduce the risk of serious problems for you or your baby if you do get an infection.

Getting prenatal care is essential. For instance:  simple blood tests can tell you whether you're immune to certain infections for example rubella and chicken pox. You'll also be tested for infections you may not know you have including urinary tract infections, HIV, group B strep and hepatitis B. If you think you've been exposed to a serious infection or you become ill, getting care in a timely manner can often help prevent complications.

You be able to do a number of things on your own, too. Critical measures like washing your hands not sharing drinking glasses or utensils, not changing cat litter, using gloves when gardening and staying away from anyone with an infectious disease will decrease your risk of getting sick.

Practicing safe sex will help prevent many sexually transmitted infections and you can take measures to avoid food-borne infections too – such as not eating certain foods, washing fruits and vegetables and making sure that your eggs, fish and meat are well cooked and your work surfaces aren't contaminated.

Here's a list of several of the infections that can affect a pregnancy:

Chlamydia, Cytomegalovirus, Flu, Zika virus, Gonorrhea, Group B strep, Hepatitis B, Herpes, HIV, Dengue fever, Chikungunya, Bacterial vaginosis, Chicken pox, Sexually transmitted infections, Rubella (German measles), Toxoplasmosis, Trichomoniasis, Listeriosis, Urinary tract infections, Fifth disease (parvovirus), Syphilis
