     Flirting is a fundamental fixture in the sexual behavior repertoire, a time-honored way of signaling interest and attraction. It is a kind of silent language spoken by men and women around the world. The ways people communicate interest are so deeply rooted in human nature that the signals are automatically understood by all: from ways of glancing to movements such as licking one's lips, to meet nature's most basic command—find a good mate and multiply.

Flirting is not a trivial activity; it requires many skills: intellect, body language, creativity, empathy. At its best, flirting can be high art, whether the flirter is vying for a soul mate, manipulating a potential customer, or just being playful.

The process of flirting allows the signaling of interest to another in small increments, which is especially appealing to a partner. Flirting is driven by emotions and instinct rather than logical thought. Yet the gestures and movements used in flirting also provide reliable clues to a person's biological and psychological health.

Flirting has many parallels in the animal world, seen in the behavioral displays many animals engage in to signal not only their availability but their suitability. For example, penguins search for small pebbles to deliver to their partner of interest. Seahorses lock their tails together for a romantic swim. Bower birds use leaves, grass, and twigs to construct elaborate nests.

Across the animal kingdom, such actions are closely tied to seasonal reproductive readiness and signal reproductive fitness by one creature to another. Among humans, the repertoire of flirting behaviors can be deployed at will and the exact meaning of any gesture is usually a matter of interpretation.

The Socialist Republic of Vietnam has stood out as one such example of how to effectively respond to the pandemic. Vietnam, which shares a border with China and is about 1,200 miles from where the outbreak was first reported in Wuhan, has overcome steep odds in the global fight against COVID-19. As of April 6, the Vietnamese government has reported 245 confirmed cases with 95 recoveries and no fatalities.

The country’s response to the outbreak has received international recognition, including from the World Health Organization and World Economic Forum, for its comprehensive, low-cost model of disease prevention. WHO representative in Vietnam, Dr. Ki Dong Park, attests the government “has always been proactive and prepared for necessary actions”.

The Communist Party of Vietnam has strengthened its anti-pandemic measures by implementing nationwide social distancing rules, such as banning outside gatherings of more than two people while keeping a distance of 6.5 feet, and temporary shutdowns of “non-essential” businesses, including restaurants, entertainment centers and tourist sites.

Supermarkets and other essential services remain open, but are instructed to safeguard customers’ health by checking their temperatures before entering the building and providing them with hand sanitizers. In addition, the government has warned against panic buying and has taken action against businesses engaged in price gouging. To ensure social security for affected workers, Vietnam has approved a 111.55 million dollar financial support package that includes covering all costs for workers in quarantine or are recovering from the disease.

Unlike the U.S. capitalist class and the Trump administration, the Vietnamese government took early measures to combat the current coronavirus epidemic. Officials began preparing strategies to combat the outbreak immediately after the first cases emerged in China.

On February 1, Prime Minister Nguyen Xuan Phuc signed Decision No.173.QD-TTG, categorizing the virus as a Class A contagious disease “that can transmit very rapidly and spread widely with high mortality rates.” This declaration of a national emergency came after the sixth case of coronavirus in the country was reported. In contrast, the Trump administration only declared a national emergency over the global pandemic on March 13, when there were at least 1,920 confirmed cases across 46 states.
