Say “I love you” with flowers, chocolates or a greeting card, but be careful when you kiss this Valentine’s Day.“Mid-February is usually the peak season for infectious diseases, such as the seasonal and H1N1 flu, mononucleosis, colds and coughs,” says Jorge Parada, MD, medical director, infectious disease at Loyola University Health System. “And don’t rely on obvious signs of illness - such as sneezing or fever as a tip off. People with infectious diseases start shedding the virus before they experience the full effect of the illness.”Drink to me only with thine eyesDrinking from the same wine glass or sharing dessert with the same fork may seem romantic, but also may lead to infections.And keep your chopstick to yourself.“Someone can have a cold sore that hasn’t erupted yet and use lip balm which is then shared, and the cold sore virus – otherwise known as herpes - is transmitted,” said Parada. Albeit less frequently, shared linens also are transmitters of infections. “A shared pillowcase, napkin or towel can also actually be a conduit for disease, especially if someone has a sore or cut,” says Parada.Do’s and don’ts for safe displays of affection Do Give and Get a Flu Shot – “It’s the gift that keeps on giving – you protect yourself, your loved one and you stop the virus from spreading to others,” said Parada. “If that isn’t sexy, and say ‘I love you’ I don’t know what does.”Don’t Share Utensils – “Humans can transmit some infections through saliva. A glass, fork or napkin can act as a bridge and pass the bug along to another person when that shared object is used by one infected person and then used by another.”Don’t Kiss or Have Close Body Contact if You Feel Unwell – “Throwing up and blowing your nose is not fun; no one wants to be ill so being upfront and honest when you feel under the weather will be appreciated.”Give The Flu The Kiss-Off Parada says that it takes 10 – 14 days after injection for the flu shot to have full preventive effect. “Get that flu shot now to increase your odds for romance on Valentine’s Day,” says Parada. “Having a flu shot is definitely sexy. It beats the flu every time!”This article was first published at www.newswise.comChanging weather or temperatures are often blamed for winter’s coughs and sniffles. But in reality, colds, coughs and the flu are infectious diseases “caught” through transmission from one human to another.“Becoming too hot or too cold can cause stress to the body, weaken the defense in fighting off infections and thus make us more vulnerable,” said Parada, who is also a professor of preventive medicine at Stritch School of Medicine. “But a person has to be exposed to a virus or bacteria to catch it.” Dr. Parada feels that winter trends such as staying indoors in crowded arenas such as shopping malls or movie theaters may promote winter colds and flu.
