While it seems that the outbreak is affecting nearly everyone in at least some way, it may be even more important for people with hypertension to stay informed. Infections with COVID-19 may be more severe in those with hypertension, and may also affect the action of antihypertensive medications.
Coronavirus Risks with Hypertension
Current data make it clear that people with underlying health conditions are at higher risk for developing more serious cases of COVID-19, including hospitalizations, the need for ventilation, or death. Overall, an estimate based on a study of 1,590 COVID-19 patients in China found that serious cases were 1.79 more likely for patients with one underlying health condition, such as hypertension, and 2.59 times more likely with 2 underlying health conditions. .

The World Health Organization (WHO) says people with hypertension are among the highest-risk groups for more serious cases of, and death from, COVID-19 . The death rate 8.4% among confirmed cases and 6.0% among all cases. In comparison, the death rate among those with no-preexisting conditions was 0.9%. In addition, ICU patients in one study were more than twice as likely to have hypertension (58.3% versus 21.6%). .*as of March 2020*

No prexeisting conditions
In addition, the increased risk of serious cases with at least two underlying conditions may be relevant, as more than half of individuals with hypertension have obesity, and nearly half have impaired fasting glucose . Prediabetes and diabetes not only raise risk for infections becoming more serious, but also for getting infected in the first place.
Why might individuals with hypertension get more serious cases of COVID-19? It is intuitive (more risk with more health conditions), but there seems to be a special link between COVID-19 and hypertension. The connection is related to angiotensin-converting enzyme 2 (ACE2) .
This enzyme acts on ACE2 receptors to increase blood pressure. The class of antihypertensives known as ACE inhibitors block this action to lower blood pressure. It appears, though, that COVID-19 and similar viruses bind ACE2. This has two main implications.
Implications of Hypertension and COVID-19
- Patients with hypertension and cardiovascular disease have higher levels of ACE2.
- Patients on ACE inhibitors and angiotensin-receptor blockers and their doctors may need to reevaluate their use of these medications if infected by COVID-19.
Standard Prevention Practices
The same things that can help prevent the spread of coronavirus in the general population can help lower your risk of getting sick. These are standard precautions for avoiding any contagious respiratory infection and are recommended by the CDC .
- Wash your hands frequently, including after using the bathroom, being in a public place, or coughing or sneezing, and before eating.
- Greet people with elbow bumps or bows instead of handshakes or hugs.
- Use a tissue or your sleeve to touch high-traffic surfaces in public areas, such as door knobs, elevator buttons, and stair banisters.
- Avoid touching your face, since germs can enter through the eyes, nose, and mouth.
- Clean your home and phone thoroughly with disinfectants.
The CDC also suggests avoiding crowds and indoor gatherings when you can. Some strategies can include:
- Watching sports events on TV instead of in person.
- Streaming religious services online instead of in your regular place of worship.
- Asking others to bring daily necessities, such as groceries and household items.
- Use video chats to keep in touch instead of going to large gatherings.

Other steps to take are to avoid contact with others however possible, such as driving yourself rather than taking public transportation and sneezing into an elbow.
